Is Blokz a regular lens with a special coating?

No. Blokz blue blocker lenses are made with a special blue-light blocking polymer from Mitsui Chemicals, a leading lens material manufacturer, that is directly incorporated into the lens materials. That means the blue- blocking technology won't chip or wear away. By absorbing blue light, this polymer prevents blue light from passing through the lens to your eye.

Does Blokz come with anti-reflective coating?

Yes. Blokz (regular and tinted) comes with a standard anti-reflective coating, and Blokz Trivex and Blokz Photochromic come with a super hydrophobic anti-reflective coating.

What does “virtually clear” mean?

Unlike typical blue blocker lenses which have a very noticeable yellow or orange tint, Blokz lenses are one of the clearest blue-light-blocking lenses on the market, with only a slight tint. However, some customers with a moderate to high prescription strength may notice a mild yellow tint as the lenses become noticeably thicker.

Is Blokz the same thing as computer glasses?

Yes and no. Zenni's Blokz blue blockers are blue-light blocking lenses that are designed for all-day wear and protection from blue light. Whether you're a heavy computer user or not, Blokz can be worn like regular glasses to protect your eyes from harmful blue light emitted from any digital device, as well as artificial fluorescent and LED light exposure. Blokz lenses are not like the yellow/orange-tinted specialty computer glasses designed specifically for computer and gaming use.

Can I order progressive or bifocal glasses with Blokz?

You can order progressive Blokz blue blocker lenses but not bifocals. However, Premium Sunglasses frames cannot be ordered with progressives at this time.

Should my child wear the Blokz lens?

Yes! Children are especially vulnerable to the effects of blue light because their eyes have not yet developed natural defenses against UV and blue light. Now that smartphones, computers, and tablets are a regular part of kids' lives, they need blue protection more than ever. We recommend Blokz Trivex® lenses for children due to their impact-resistant properties.

How does blue light affect the eyes?

Prolonged exposure to high-energy visible (HEV) blue light can lead to eye strain and blurred vision. Studies have shown that it may also damage the retinal cells which can lead to an increased risk of developing age-related macular degeneration. Macular degeneration leads to vision loss over time. The Blokz blue blocker lenses block blue light and provide maximum UV coverage to protect your eyes.
