Do all GP lenses have identical UV protection levels?

Do all GP lenses have identical UV protection levels?

• A. True
• B. False
• C. Only some have UV blockers
• D. It varies by brand and design

Answer: (B)

UV protection in gas-permeable lenses is not standardized. Depending on the material and design, a GP lens may include UV-blocking additives that reduce UV-A and UV-B transmission, or it may offer little to no UV protection. Because the edge of the lens and surrounding eye tissues can still be exposed to UV light, even lenses with blockers don’t guarantee full protection. So there isn’t a single identical UV protection level across all GP lenses; it varies by brand and design. If UV protection is a priority, use sunglasses with complete UV coverage in addition to wearing the lenses.
