Ultra violet (UV) radiation in sunlight is commonly divided into UVA and UVB and your sunglasses should block both forms.
People who spend long hours outdoors without adequate eye protection can develop photokeratitis, reversible sunburn of the cornea. This is painful condition can result in temporary loss of vision. When sunlight reflects off of snow, sand and water, it further increases exposure to ultraviolet radiation. These invisible high-energy rays lie just beyond the violet end of the visible light spectrum. The same harmful rays that damage the skin, can also increase your risk of developing eye problems such as cataracts- a clouding of the eye's lens that develops over years.
