Why is UV protection important in eyewear?

UV protection is essential in eyewear because it helps shield the eyes from harmful ultraviolet (UV) rays produced by the sun. Prolonged exposure to these rays can lead to various eye issues, including cataracts, macular degeneration, and photokeratitis (a sunburn of the eye). By having UV protection in lenses, wearers can significantly reduce their risk of developing these serious eye conditions.

While enhancing visual acuity, reducing glare during nighttime driving, and improving the durability of the lenses can be valuable features of eyewear, they do not specifically address the harmful impacts of UV radiation on eye health. Therefore, the focus on protecting the eyes from UV rays highlights the primary health-related benefit of UV protection in eyewear.
