UV And Your Eye Health
Daylight exposes us to a lot of UV radiation daily, whether it’s sunny or cloudy. Even on cloudy days, UV irradiance can reach 70-75% of a clear sky day at ground level.
UV radiation has several beneficial effects for us including vitamin D production via skin exposure. It also stimulates the production of melanin, your body’s own protection against sunburn that causes a tanned complexion.
However, if your unprotected skin is exposed to UV radiation for a prolonged period, it can cause damage such as photo ageing, wrinkles, and in severe cases, skin cancer. To protect the skin, we wear sunscreen, but we really don’t have a lot of options when it comes to protecting our eyes against harmful UV rays.
It is often forgotten that UV rays are also harmful to our long-term eye health and that it can cause damage to the area around the eyes. Unfortunately, only 1 out of 5 lenses fully block UV radiation up to 400nm. That means the other 4 out of the 5 lenses don’t block or only marginally block UV radiation. As a result, UV rays are transmitted through the lens and can potentially harm both your eyes and skin, leading to detrimental eye conditions such as:
Protect your eyes with ZEISS Lenses that come with UVProtect technology, which offers full UV protection in all clear plastic lenses – all day, every day. These lenses block harmful UV rays up to 400nm, which is the same standard of UV protection premium sunglasses provide.
Blurry Vision Explained
Blurry or distorted vision is most often caused by refractive errors which prevent the eye from focusing light directly on the retina. Your ZEISS lenses redirect light entering the eye to ensure the clearest possible view.
