Pupillary Distance
 

Use the PD filter to show only glasses that will work for your PD.

The PD or Pupillary Distance is the distance between the pupils of the eyes, center to center, in millimeters. Most people have a PD between 54mm and 74mm.  If you received two values, such as 31/31.5, then the values are the distance from the center of your nose to each pupil center.  A  PD should be provided as part of your prescription.

If you received two values, click on Dual PD and select your values - Note the RIGHT is on the left side, and LEFT is on the right.  

If you received a single value, then click on Single and select this value.

You may have received two PD numbers that differ by a value of 3mm (such as 62/59).  The larger value represents the distance PD, which is what you will normally need for our site.  The smaller value is used only for ordering single-vision reading glasses.

If your most recent eye exam did not include the PD value, but a previous one did, you can use the previous value. It does not change over time (except for children, of course).

While an optometrist's PD value is always recommended, you can determine the measurement with a friend or family member's help. Have your assistant hold a ruler just below your eyes and measure the distance in mm from pupil center to pupil center. Focus straight ahead at a distant object, and keep your eyes steady. Take a few measurements for consistency.

Do not guess your PD value or your glasses will not work for you. Likewise, do not try to measure anything on your current glasses, as there is no way to measure your PD from them.

BIFOCAL

A lens with two fields of vision separated by a line. Generally the top is designated for distance-vision or computer-distance and the bottom for near-vision work such as reading.

The total lens height for a Bifocal lens must be 30mm or greater. We recommend a taller lens for more comfortable wear, but 30 mm is the minimum height for a bifocal lens. If the frame chosen has a lens height smaller than 30mm, a different frame must be chosen for Bifocal lenses.

In a Bifocal lens, the two fields of vision are specifically differentiated by a visible line. The bottom reading area is 28mm wide and is positioned just below the centerline of the lens. The physical position of the bi-focal area will be affected by the physical height of the lens chosen.

Progressive

This refers to the lens design which includes three fields of vision, without lines, and is sometimes referred to as a "no-line bifocal".

The lens height for a progressive lens must be 30mm or greater. We recommend a taller lens for more comfortable wear, but the minimum lens height is 30 mm. If this frame has a lens height smaller than 30mm, a different frame must be chosen for progressive lenses.

In a progressive lens, the shape of the corrected part of the lens is approximately that of a funnel or a mushroom, with the top portion for distance-vision, narrowing to the lower middle for mid-range, finally to the bottom portion for the near-vision or reading. The reading area is approximately the lower quarter, central third of the lens.

It is a good design, without lines, for general use. People sometimes prefer a single-vision lens for extended reading or up-close work.

Anti-Reflective Coating

Anti-Reflective (AR) coatings improve both the vision and the appearance of your glasses.  AR coatings significantly reduce reflections while driving or from overhead light.  They also make your glasses less reflective in photographs, so your eyes shine through rather a reflection.  AR coatings signficantly improve night driving by reducing glare, reflections and halos around lights.

For a technical explanation, an AR coating is a layered metal oxide coating applied to both sides of the lens that greatly reduces both the internal and external the reflections on the lens surface while allowing more light through the lens.

Super Hydrophobic (water-resistant) Anti-Reflective Coating (Select lenses only):

This has all the properties of a regular AR coating, plus the added benefit of a water resistant coating that repels dirt and water, and is easier to clean.

OD-SPH

SPH, for Spherical, refers to the refractive correction in the prescription.  The Spherical correction is for near (-) or far (+) sightedness.  If "PL" or "Plano" is written for the OD-SPH on your prescription, the value to be entered is 0.00.

OD-SPH is spherical correction for your right eye.

OS-SPH

SPH, for Spherical, refers to the refractive correction in the prescription.  The Spherical correction is for near (-) or far (+) sightedness.  If "PL" or "Plano" is written for the OS-SPH on your prescription, the value to be entered is 0.00.

OS-SPH is spherical correction for your left eye.

OD-CYL

CYL, for Cylinder, refers to the strength of the correction for the astigmatism in the eye.  It can be either positive or negative.  If there is an OD CCYL value, there must be an OD Axis value.

If "DS" or "SPH" or "spherical" is noted in this space on your prescription, you have no astigmatism in that eye and the value to be entered is 0.00.

OD-CYL is cylinder correction for your right eye.

OS-CYL

CYL, for Cylinder, refers to the strength of the correction for the astigmatism in the eye.  It can be either positive or negative.  If there is an OS CYL value, there must be an OD Axis value.

If "DS" or "SPH" or "spherical" is noted in this space on your prescription, you have no astigmatism in that eye and the value to be entered is 0.00.

OS-CYL is cylinder correction for your left eye.

OD AXS

AXS, or Axis, refers to the angle of the correction for the astigmatism in the eye (if one exists) from 1 to 180.  If there is an OD Axis value, there must be an OD CYL (Cylinder) value.  If there is no OD Cylinder value, or if the OD Cylinder value is Zero, then the OD Axis value is Zero.

The Axis value is usually written as 3 digits, which means if your Axis value is 5, it is often written as 005. This Axis value is still 5, regardless of how it is displayed.

OD Axis is Axis correction for your right eye,

OS AXS

AXS, or Axis, refers to the angle of the correction for the astigmatism in the eye (if one exists) from 1 to 180.  If there is an OS Axis value, there must be an OS CYL (Cylinder) value.  If there is no OS Cylinder value, or if the OS Cylinder value is Zero, then the OS Axis value is Zero.

The Axis value is usually written as 3 digits, which means if your Axis value is 5, it is often written as 005. This Axis value is still 5, regardless of how it is displayed.

OS Axis is Axis correction for your left eye,

Clip-on Sunglasses - Gray

These are lightweight, polarized, 80% gray clip-on sunglasses.

All clip-ons are custom cut to closely match the glasses you are ordering . These are not the common heavy, non polarized, generic drug-store Flip-Up clip-ons you might find elsewhere. Ours is not a flip-up type, but has small rubberized clips that will go over and blend into the eyeglass frame.

The drop-down menu below allows for the order of multiple clip-ons

Another option for clip-on sunglasses are the Sunshade frames. These have an exact matching magnetic snap-on polarized sunlens with no "clips" at all.

Example Gray Clip-on Sunglasses:

Tint


Permanent Lens Tint Colors:

This is a permanent tint on the lens, not to be confused with the Photochromic lens which changes shade according to the amount of sunlight.

An 80% tint is a dark sunglass tint for bright outdoor conditions. We recommend the 80% Gray tint for most sunglass applications.

A 50% tint is a medium-light sunglass tint that is not too dark to make it unusable indoors, while giving some medium/light sunshade protection outdoors.

A 10% tint is a very light cosmetic/fashion tint barely noticeable to the wearer, but provides a slight hint of color to people looking at the wearer.

All of our eyeglass lenses, tinted or clear, have full 100% UV protection built-in to protect the eyes from harmful sunrays.

Since the brightness and tint density displayed can vary on each monitor for the identical image, even on those hooked up to the same computer, the color examples displayed above may not be an exact match to the tint you will receive. Nevertheless, the color chart above should give you a good indication of how they will look.

Prescription Type
 

Select your prescription type to show only compatible frames. 

Prescription type descriptions:

• Single Vision lenses are the standard eyeglass prescription. These glasses are for one field of vision across the entire lens, whether specifically for distance vision, near-vision reading glasses or somewhere in-between such as computer-distance glasses.  There are no lens height requirements for single vision prescriptions.

 

• Bifocals are lenses with two fields of vision separated by a line.   Usually the top is designated for distance-vision or computer-distance and the bottom for near-vision work such as reading.  The bottom reading area is 28mm wide and is positioned just below the centerline of the lens. The position of the bi-focal area will be affected by the height of the lens chosen.  The lens height for a Bifocal lens must be 30mm or greater.




• Progressive lens design includes three fields of vision, without lines, and is sometimes referred to as a "no-line bifocal".  In a Progressive lens, the shape of the corrected part of the lens is approximately that of a funnel or a mushroom, with the top portion for distance-vision, narrowing to the lower middle for mid-range (corridor), finally to the bottom portion for the near-vision or reading. The reading area is approximately the lower quarter, central third of the lens. The height of the progressive corridor can be short, medium or long, and is dependent on the height of the lens: the taller the lens, the longer the corridor. The corridor begins just above the centerline of the lens.  The lens height for any Progressive lens must be 30mm or greater.

Lens Information

Lenses are chosen by their index, material, and tint.

Index:

The Index value refers to the refractive quality of the lens, or the degree to which the lens bends light passing through it. Generally, the higher the index, the thinner the lens.

For normal, single vision prescription values Zenni Optical recommends a lens with a mid-index of 1.57. It is thin and light, and is included for no extra cost with your glasses. For prescriptions less than -4/+3 a higher index lens will not produce a noticeably thinner lens.

Lenses with index values of 1.61 and 1.67 are appropriate for stronger prescriptions beyond -4 or +3. Lenses with index values of 1.74 are best suited for prescriptions beyond -5.

Material:

Unless otherwise specified, most lenses are made from advanced resin plastic.  The exception to this is Polycarbonate lenses.  No lenses we sell are made from old fashioned glass.

A "PC" lens, or PolyCarbonate, is extremely impact resistant, as well as very thin and light with an index of 1.59. We highly recommend Anti-Reflective (AR) coating with PC lenses to reduce glare and improve night-vision. 

Tint:

Most clear lenses are able to take one of our solid or gradient tints.  These tints are available in variety of colors and strengths.

Photochromic change their tint according to how much UV sunlight they receive.  The shade of the lenses is slightly lighter than regular sunglasses.  They take a minute or two to darken, or to become clear when moved out of the sun. Automobile windows block UV so these lenses would darken less in a car.  Our photochromic lenses come pretinted in a variety of colors, but cannot be tinted other colors.  Zenni Optical also offers Transitions® brand photochromic lenses, which contain patented photochromic dyes.

We also offer pre-tinted polarized lenses with an 80% sunglass tint.  These are available in a choice of materials.

Other tint options include our sunglass clip-ons, or magnetic sunglass snap-on models.

Frame Fit Upload

Use the Zenni Frame Fit™ upload tool to see eyeglass frames displayed on your face.

To use:

• Have a clear photo of just your face, facing straight ahead, without glasses.  It is best to have good lighting.  The sample faces are good examples.
• Have your PD (Pupillary Distance) handy.  Without this measurement, your picture will not be accurate!
• Slightly tilted pictures will be corrected, but rotated 90 degrees or upside down will not work.
• The system will try to identify your pupils automatically, but you can manually choose them for the most accurate display.
• You can upload more than one face - including family members and friends!
• Zenni Frame Fit™ works for young and old - great for finding frames for your children while they're at school!

NV-ADD

Sometimes seen on your prescription as just "NV" or "ADD".  "NV" stands for "Near-Vision."  This is the reading portion of a lens in a multi-focal prescription, and this number indicates the strength of the overlay on the lens, for reading. It is typically the same positive number, for both eyes, although it may be written only once on your prescription.  It may also be written as a large, positive number, across both the OD and OS lines of your prescription. 

This will clear all prescription values from this page.  It will also clear previously imported prescription values.

Import Prescription

You can import prescriptions you have saved in your account, or from previous orders.  You can also go to the "my prescriptions" section of your account to enter or edit a prescription in your account.

Accessories

For non-prescription items, such as sunglasses, cases, and more, select the item you are looking for below.

Personalize

Click on the box to show your choices for personalizing your frame.  These options include putting text on the inside or outside of the temple, as well as choosing a putting a picture on the frame temples.

Frame Pictures

Add a picture to the temple arms of your glasses.  Choose from our library of artwork and select a color that works best with your frame.  We suggest choosing a contrasting color - not black artwork for a black frame.

If you choose custom text and a picture, the picture will always be at the front of the temple arms, closest to the lens.

Help tip is coming soon!

Gender

Click to select men's or women's frames.  Choosing children's frames will display frame results with a smaller physical size. 

Uncheck all boxes for unfiltered results that will display all frames.

Frame Personalization

Add a picture to the temple arms of your frames, or add your own custom text to make them your own.

Custom Frame Text

Add your own text to the inside and out of the frame temple arms.  Type your text, select the text color, and choose your font.  You can write text for both the inside and outside of the temple arms.  There is a limit for how many letters will fit.

A good suggestion for the inside is to put your phone number, in case you lose your frames.

Note: Inside text will be only on one temple arm.  Outside text is on both temple arms.  Please select a text color that works best with your frame - if you have a black frame do not select a black text color.  If you choose frame text and a frame picture, the picture will always be at the front part of the temple arms, closest to the lens.

We cannot accept copyrighted works for frame text, such as brand names.

Clip-on Sunglasses - Amber

These are lightweight,  polarized, 80% amber clip-on sunglasses.

All clip-ons are custom cut to closely match the glasses you are ordering . These are not the common heavy, non polarized, generic drug-store flip-up clip-ons you might find elsewhere. Ours is not a flip-up type, but has small rubberized clips that will go over and blend into the eyeglass frame.

The drop-down menu below allows for the order of multiple clip-ons

Another option for clip-on sunglasses are the Sunshade frames. These have an exact matching magnetic snap-on polarized sunlens with no "clips" at all.

Example Amber Clip-on Sunglasses:

Frame Material

Select the material for your eyeglass frames.  You may select more than one material type, or clear all checkboxes to show all material types.

SPH SPHERE

SPH, for Spherical, refers to the refractive correction in the prescription.  Minus (-) are for near sightedness, and Plus (+) values are for far sightedness.   If "PL" or "Plano" is written for the either SPH value on your prescription, you should select a value of 0.00.

OD-SPH is spherical correction for your RIGHT eye.

OS-SPH is spherical correction for your LEFT eye.

Please note: It is rare to have one eye have a + SPH and the other eye have a - SPH.  Please double check your prescription to make sure it is correct.

Also, please check that you are selecting - values for near sightedness, and + value for far sightedness.

CYL CYLNDER

CYL, for Cylinder, refers to the strength of the correction for the astigmatism in the eye.  It can be either positive or negative.  If there is an OD CYL value, there must be an OD Axis value.

If "DS" or "SPH" or "spherical" is noted in the CYL space on your prescription, you have no astigmatism in that eye.  In that case, enter 0.00..

OD-CYL is cylinder correction for your right eye.

OS-CYL is cylinder correction for your left eye.

AXS AXIS

AXS, or Axis, refers to the angle of the correction for the astigmatism in the eye (if one exists) from 1 to 180.  If there is an OD Axis value, there must be an OD CYL (Cylinder) value.  If there is no OD Cylinder value, or if the OD Cylinder value is Zero, then the OD Axis value is Zero.

The Axis value is usually written as 3 digits, which means if your Axis value is 5, it is often written as 005. This Axis value is still 5, regardless of how it is displayed.

OD Axis is Axis correction for your right eye.

OS Axis is Axis correction for your left eye.

NV-ADD

Sometimes seen on your prescription as "NV, ADD, Near, Reading, or Reading Addition."  "NV" stands for "Near-Vision."  This is the reading portion of a lens in a multi-focal prescription, and this number indicates the strength of the reading portion of the lens.  We display this inbetween OD (Right) and OS (Left) since it is almost always the same value for both eyes.

PRISM

Prism is the prismatic power used to correct vision displacement, like double vision.  Most eyeglass prescriptions do not have prism correction.

Prism is measure in prism diopters, or p.d., not to be confused with PD for Pupillary Distance.

A prescription with prism prescription will have two values per eye.  The Prism Value are the prism diopters, and the Base Direction.  Base Direction is usually written as BU for Base Up, BD for Base Down, BI for Base In, and BO for Base Out.

If you do not have prism correction in your prescription, do not include prism values since it will negatively affect your vision.

Lens Information

Lenses are chosen by their index, material, and tint.

The lenses are divided into standard clear lenses, and lenses which contain a built in polarized tint or photochromic lenses, which can change from clear to dark with sunlight.  Most clear lenses can have af tint added to them.

Based on the values in your prescription, we try to recommend the lens that will give you the optimum vision correction and thinness of lens.  We do not recommend more expensive high index lenses if we do not think it will result in a noticeably thinner lens, though you are free to choose any lens available.  The recommended lens will always be clear.  If you wish to have a polarized or photochromic lens, you should select a lens with the same index (or higher).

Index:

The Index value refers to the refractive quality of the lens, or the degree to which the lens bends light passing through it. Generally, the higher the index, the thinner the lens.

For normal, single vision prescription values Zenni Optical recommends a lens with a mid-index of 1.57. It is thin and light, and is included for no extra cost with your glasses. For prescriptions less than -4/+3 a higher index lens will not produce a noticeably thinner lens.

Lenses with index values of 1.61 and 1.67 are appropriate for stronger prescriptions beyond -4 or +3. Lenses with index values of 1.74 are best suited for prescriptions beyond -5.

Material:

Unless otherwise specified, most lenses are made from advanced resin plastic.  The exception to this is Polycarbonate lenses.  No lenses we sell are made from old fashioned glass.

A "PC" lens, or PolyCarbonate, is extremely impact resistant, as well as very thin and light with an index of 1.59. We highly recommend Anti-Reflective (AR) coating with PC lenses to reduce glare and improve night-vision. 

Tint:

Most clear lenses are able to take one of our solid or gradient tints.  These tints are available in variety of colors and strengths.

Photochromic:

Photochromic lenses change their tint according to how much UV sunlight they receive.  The shade of the lenses is slightly lighter than regular sunglasses.  They take a minute or two to darken, or to become clear when moved out of the sun. Automobile windows block UV so these lenses would darken less in a car.  Our photochromic lenses come pretinted in a variety of colors, but cannot be tinted other colors.  Zenni Optical also offers Transitions® brand photochromic lenses, which contain patented photochromic dyes.

Polarized:

We also offer pre-tinted polarized lenses with an 80% sunglass tint.  These are available in a choice of materials.  Polarized lenses block light from certain angles, and are very effecting at cutting glare and harsh reflections.

Other tint options include our sunglass clip-ons, or magnetic sunglass snap-on models.

Recommended lenses

Based on the values in your prescription, we try to recommend the lens that will give you the optimum vision correction and thinness of lens.  We do not recommend more expensive high index lenses if we do not think it will result in a noticeably thinner lens, though you are free to choose any lens available. 

The recommended lens will always be clear.  If you wish to have a polarized or photochromic lens, you should select a lens with the same index (or higher).

Standard Solid Lens Tint

A lens tint will color and darken your lenses, either for fashion or for use as sunglasses.

This is a solid lens tint, meaning that the color and strength of the tint will be the same from the top to the bottom of the lens.  Gradient tints are darker at the top than at the bottom of the lens.

This is a permanent tint on the lens, not to be confused with the Photochromic lens which changes shade according to the amount of sunlight.


Permanent Lens Tint Colors:

An 80% tint is a dark sunglass tint for bright outdoor conditions. We recommend the 80% Gray tint for most sunglass applications.

A 50% tint is a medium-light sunglass tint that is not too dark to make it unusable indoors, while giving some medium/light sunshade protection outdoors.

A 10% tint is a very light cosmetic/fashion tint barely noticeable to the wearer, but provides a slight hint of color to people looking at the wearer.

Gradient Lens Tint

A lens tint will color and darken your lenses, for use as sunglasses.  Gradient tints are darker at the top than at the bottom of the lens.  They will have an 80% sunglass level tint at the top.  If you wish to have a lighter tint, or a uniform color from top to bottom, please select from the Solid Tints.

This is a permanent tint on the lens, not to be confused with the Photochromic lens which changes shade according to the amount of sunlight.

All of our eyeglass lenses, tinted or clear, have full 100% UV protection built-in to protect the eyes from harmful sunrays.

Since the brightness and tint density displayed can vary on each monitor for the identical image, even on those hooked up to the same computer, the color examples displayed above may not be an exact match to the tint you will receive. Nevertheless, the color chart above should give you a good indication of how they will look.

Options and Accessories

Here you can choose from lens coatings and add-on products.

Lens Coatings

Lens Coatings consist of anti-reflective coatings and mirror finish.  Anti-reflective coatings reduce glare, and are especially useful for improving problems from reflections due to overhead lights, or oncoming headlights when driving at night.

Hydrophobic means water resistant, and is helpful at keeping the lenses fog, dirt, and dust free.  It also helps in making the lenses easier to clean - dirt comes off much quicker when wiped.

Olephobic means oil resistant.  It has all the advantages of dirt and easy clean advantages of hyrdrophobic, plus extra resistance for fingerprints and sweat.

Mirror finish adds a reflective coating on the front side of the lens with a very slight coloring.  They are often best combined with lens tints for sunglass use.  They are not recommended for extended use indoors, especially with computers and overhead lights, since there will be some visible reflections.

Accessories

Clip-on sunglasses are custom made polarized lenses with 80% sunglass tint, available in a choice of colors.  These are not the common heavy, non polarized, generic drug-store Flip-Up clip-ons you might find elsewhere. Ours is not a flip-up type, but has small rubberized clips and a very light and narrow bridge wire between the lenses that will go over and blend into the eyeglass frame.

Clip-on sunglasses should not be used with tinted lenses.  They can be useful with photochromic lenses for use when driving, since the windshield glass will block the UV light need to trigger the phtochromic darkening.

Anti-Reflective Coating

Anti-Reflective (AR) coatings improve both the vision and the appearance of your glasses.  AR coatings significantly reduce reflections while driving or from overhead light.  They also make your glasses less reflective in photographs, so your eyes shine through rather a reflection.  AR coatings signficantly improve night driving by reducing glare, reflections and halos around lights.

An AR coating is a layered metal oxide coating applied to both sides of the lens that greatly reduces both the internal and external the reflections on the lens surface while allowing more light through the lens.

Super Hydrophobic (water-resistant) Anti-Reflective Coating (Select lenses only):

Oleophobic coatings come highly recommended, and are the newest generation of AR coatings.   The Oleophobic coating has all the benefits of regular and super-hydrophobic (water resistant) AR coatings, and adds oil resistance, which repels dirt, sweat, and fingerprints.  The lenses stay clearer, and are easier to clean than ever before.

1.50 Bifocal (with a line)

A low-index lightweight lens, commonly used for the majority of glasses made. "Index" refers to the refractive quality of the lens, or the degree to which the lens bends light passing through it. The 1.50 index lens has good impact-resistance and is appropriate for most prescriptions.

Bifocal lenses contain two fields of vision separated by a line, generally with the top for distance or computer-distance, and the bottom for near-vision work such as reading. The reading area is 28mm wide and is positioned just below the centerline of the lens. The physical height of the bifocal area will be affected by the height of the lens chosen.

The total lens height for a Bifocal lens must be 30mm or greater. We recommend a taller lens for more comfortable wear, but 30 mm is the minimum height for a bifocal lens. If the frame chosen has a lens height smaller than 30mm, a different frame must be chosen for bifocal lenses.

1.50 Transitions® Photochromic + Progressive – Gray

A low-index lightweight lens, commonly used for the majority of glasses made. "Index" refers to the refractive quality of the lens, or the degree to which the lens bends light passing through it. The 1.50 index lens has good impact-resistance and is appropriate for most prescriptions.

Transitions® lenses contain patented photochromic dyes which cause the lens to activate - or darken - when exposed to ultraviolet (UV) rays from sunlight. When the UV light diminishes, the lenses fade back to clear. As outdoor light conditions change, the level of darkness adjusts, creating just the right level of tint and allowing just the right amount of light to enter the eyes at any given time. This action allows Transitions® lenses to help protect your eyes from the light you can see - reducing glare, diminishing eye strain and fatigue and enabling you to distinguish contrast more easily.

Progressive lens design includes three fields of vision, without lines, and is sometimes referred to as a "no-line bifocal".

In a Progressive lens, the shape of the corrected part of the lens is approximately that of a funnel or a mushroom, with the top portion for distance-vision, narrowing to the lower middle for mid-range (corridor), finally to the bottom portion for the near-vision or reading. The reading area is approximately the lower quarter, central third of the lens. The height of the progressive corridor is dependent on the height of the lens, and begins just below the centerline of the lens.

1.57 Progressive (No-line bifocal)

The height of the progressive corridor is dependent on the height of the lens, and begins just below the centerline of the lens.

1.57 Mid Index Progressive (no-line bifocal) - Photochromic Lens - Gray

A mid-index lens is thinner and lighter than the commonly used 1.50 low-index lens and is appropriate for most low and mid strength prescriptions. "Index" refers to the refractive quality of the lens, or the degree to which the lens bends light passing through it.

Photochromic lenses gradually darken outside in sunlight to become sunglasses. The shade in the lenses is determined by the amount of sunlight hitting the lens, and when moved indoors out of the sunlight, the lens returns to clear.

Progressive lens design includes three fields of vision, without lines, and is sometimes referred to as a "no-line bifocal".

Mirror Finish - Blue

Our mirror finish adds a reflective coating on the front side of the lens.  From the outside, there is a slight blue color reflected.  The color is not the same as a tint.  It does not darken the lens.  The blue coloring is helpful at reflecting harmful blue light, and reduces heat that can hit the eye.  When used without a tint, there is a amber cast when looking through the lenses.

The mirror finish coating is often best combined with lens tints for sunglass use. 

The mirror finish has an oleophobic coating to repel oil from sweat and fingerprints, and to help keep the lenses clean and easy to clean.  On the back side of mirror finish lenses is an anti-reflective coating, to reduce reflections seen from light entering the sides.

They are not recommended for extended use indoors, especially with computers and overhead lights.

Clip-on Sunglasses - Gray Gradient

These are polarized clip-on sunglasses with a gradient tint.  Gradient tints are darker at the top than at the bottom.

Each pair of clip-on sunglasses is custom made to match the shape of the lenses . These are not the common heavy, non-polarized, generic drug-store flip-up clip-ons you might find elsewhere. Ours is not a flip-up type, but have small rubberized clips between the lenses that will go over and blend into the eyeglass frame.

The drop-down menu below allows for the order of multiple clip-ons

Another option for clip-on sunglasses are the Sunshade frames. These have an exact matching magnetic snap-on polarized sunlens with no "clips" at all.
