UV rays and your eyes
Posted on June 22nd, 2009 10 commentsExtended exposure to the sun’s UV rays has been linked to eye damage, including cataracts, macular degeneration. Over exposure to UVB rays can cause photokeratitis, commonly known as ’snow blindness’ which causes temporary vision loss for up to 48 hours – the risk for this condition is greater at high altitudes due to the increased levels of UVB, but can occur anywhere there is snow. You must therefore ensure that the sunglasses you use in such conditions have adequate UVB protection, in the same way as you should ensure you are using an adequate sunblocking cream for your skin. Surprisingly, cloud cover doesn’t affect UV levels significantly. Your risk of UV exposure can be quite high even on hazy or overcast days.

Fishing with polarized lenses.
Posted on June 22nd, 2009 10 commentsPolarized sunglasses take the glare off the water surface allowing you to see below the water line. SEE THE FISH BEFORE THEY ARE HOOKED. Fishing sunglasses also protect and rest your eyes from the extra ultraviolet radiation that’s reflected off the water surface, making your eyes feel less tried at the end of the day.
