UV400 protection is non-negotiable for eye health, as it blocks all harmful UVA and UVB rays that cause long-term damage. When shopping for sunglasses or prescription eyewear, prioritize lenses with clear UV400 certification and avoid products with vague labeling.

Many people use a pair of sunglasses for many years. In fact, sunglasses also have a shelf life, which is related to the wearing time, lens material, wearing habits, regional sunlight, and so on. Generally speaking, the best usage period for sunglasses is about two years, and it is best to replace them with a new pair after that.
