Polycarbonate lenses are impact‑resistant lenses made from a durable thermoplastic material originally developed for aerospace and bulletproof applications. They are significantly thinner and lighter than traditional glass or standard plastic lenses. In short: Polycarbonate = tough, light, and safe.
How polycarbonate is different from regular lens materials
Most standard prescription lenses are made from CR‑39 plastic (a traditional optical polymer). Polycarbonate is a completely different material. It was invented in the 1970s for jet fighter canopies and space helmet visors. The material is naturally shatter‑proof and flexible, which makes it ideal for safety glasses, children’s eyewear, sports sunglasses and goggles, etc.
The key benefits of polycarbonate lenses
- Extreme impact resistance: Polycarbonate is 10 times more impact‑resistant than standard plastic lenses. It won’t shatter on impact – a critical safety feature.
- Thinner and lighter: Up to 30% thinner than standard plastic lenses, and noticeably lighter.
- Built-in UV protection: Blocks 100% of UVA and UVB rays - no coating needed.
- Scratch‑resistant coating included: Raw polycarbonate is soft and scratches easily, so quality lenses always come with a hard coating.
- Compatible with most frame types: Works with rimless, semi‑rimless, and full frames.
Who should choose polycarbonate lenses?
✅ Children and teenagers: They are active, rough on eyewear, and need shatter‑proof safety.
✅ Adults with active lifestyles: Sports, outdoor work, or any activity where glasses might get hit.
✅ Safety glasses and protective eyewear: Required by OSHA for many jobs.
✅ People who want lighter glasses: Especially helpful for higher prescriptions where standard plastic would be thick and heavy.
✅ Anyone concerned about eye safety: One unexpected impact can save your vision.
❌ Less ideal for: People who demand absolute best optical clarity (e.g., professional photographers) or those on a very tight budget.
Are polycarbonate lenses safe for sports?
Yes – polycarbonate is the #1 choice for sports eyewear. It meets or exceeds ANSI Z87.1 impact standards for safety glasses. It will not shatter on impact - it may scratch or dent, but it will not break into sharp shards.
Sports that require polycarbonate lenses:
- Baseball and softball
- Basketball
- Soccer
- Cycling
- Skiing and snowboarding
- Racquetball and squash
- Paintball and airsoft
Polycarbonate lenses are the default recommendation for children, athletes, safety glasses, and anyone who values impact protection over absolute optical perfection. For a typical adult wearing single‑vision glasses for daily life, polycarbonate offers an excellent balance of safety, weight, and cost.
