What are Polycarbonate Lenses?

Polycarbonate is a type of thermoplastic polymer that is exceptionally durable and lightweight. Initially developed for aerospace applications, polycarbonate found its way into the eyewear industry due to its high impact resistance.

Advantages of Polycarbonate Lenses

Polycarbonate lenses offer several advantages over traditional lens materials like plastic.

  • Impact Resistant: Polycarbonate lenses are impact-resistant, making them ideal for individuals with an active lifestyle or those who work in environments where eye protection is crucial.
  • Thin Profile: Polycarbonate lenses can be made thinner than conventional plastic lenses, improving the aesthetic appeal of your eyeglasses without compromising their strength.
  • UV Protection: Polycarbonate lenses come with built-in ultraviolet (UV) protection, shielding your eyes from harmful UV rays.
  • Lightweight: Despite their durability, polycarbonate lenses are significantly lighter than glass lenses. This lightweight nature contributes to greater comfort, especially during extended wear.
  • Prescription Compatibility: These lenses can accommodate a wide range of prescriptions, making them suitable for individuals with varying vision needs, including those with stronger prescriptions.

Considerations When Choosing Polycarbonate Lenses

While polycarbonate lenses offer numerous benefits, there are a few considerations to keep in mind.

  • Scratch Resistance: While inherently durable, polycarbonate lenses can still scratch. Opting for scratch-resistant coatings can enhance their longevity.
  • Cost: Polycarbonate lenses may be slightly more expensive than standard plastic lenses, but their durability and safety features often justify the investment.

Who Should Consider Polycarbonate Lenses?

  • Active Individuals: Athletes, outdoor enthusiasts, and those with physically demanding jobs can benefit from the impact resistance of polycarbonate lenses.
  • Children: Due to their durability and lightweight nature, polycarbonate lenses are often recommended for children’s eyewear.
  • Safety Concerns: Anyone prioritizing safety and eye protection should consider polycarbonate lenses, especially in environments where eye hazards are prevalent.
