UV protection is any measure taken to safeguard the eyes and skin from the harmful effects of ultraviolet (UV) radiation from the sun. In terms of eyewear, this means lenses that are manufactured or coated to block 100% of both UVA and UVB light, preventing these high-energy rays from damaging the eye's internal structures.
read more about uv protection ...The eye is highly susceptible to cumulative sun damage. Over a lifetime, unprotected exposure significantly increases the risk of serious, vision-impairing conditions like cataracts (clouding of the lens) and pterygium (a growth on the eye's surface). Consistent, 100% UV protection is crucial because this damage is permanent and irreversible.
For full protection, you need two things:
2. UV-Blocking Contact Lenses: These provide a constant layer of protection over the cornea and lens, regardless of whether you're wearing sunglasses. Using both forms together offers the strongest defense.
While UV protection is mainly focused on radiation damage, the comfort it provides is a secondary benefit. By reducing the invisible stressors from UV light, high-quality protection reduces eye fatigue, squinting, and strain, making it much easier to enjoy the outdoors comfortably.

What is the difference between UVA and UVB protection?
UVA rays penetrate deeply, causing long-term, cumulative damage. UVB rays affect the surface of the eye, leading to immediate issues like corneal sunburn (photokeratitis). Full UV protection must block 100% of both types.
Do all contact lenses offer UV protection?
No. Only contact lenses that are specifically manufactured with UV-blocking additives offer protection. Always check the box or product description to confirm it has a Class 1 or Class 2 UV rating.
Is UV protection needed on cloudy days?
Absolutely. Up to 80% of UV rays can penetrate cloud cover. It's important to treat UV protection as a year-round, daily requirement, just like a prescription.
