Ultra Violet Radiation

There is increasing scientific concern about the thinning of the ozone layer over Northern Europe. The reduction of this protective layer exposes us all to greater risks. The visual risk is that the crystalline lens of the eye may become prematurely aged by excessive exposure. The UV spectrum extends from around 400nm down to approximately 1nm where it overlaps with X radiation. The main concerns are UVB, which is responsible for sunburn and snow blindness, and UVA, which is possibly the most dangerous, capable of causing chronic eye damage, especially at low dose exposure over a long period of time. This is a particular concern for children who face many years of increasing exposure to UV radiation.

Harmful UV rays are present all year round. As with your skin your eyes need protection. Good quality ophthalmic tints and photochromic tints will absorb UV to 400nm. We are also able to apply an almost colourless UV 400 protective filter to most prescription lenses for a modest fee of £10 per pair.
