Re: [aus-soaring] Best sunglasses for gliding ?

Mandy,   You do not mention that wrap-around dark glasses are required to prevent pterygium formation because of the focussing effect of the cornea of light that comes from the side.  Certainly, dust aggravates pterygium (is plural pterygia?) but the primary cause is side- UV-light.   I read somewhere medical that blue eyed people are more prone to pterygium.  This could possibly be due to the blue iris reflecting more side-light off it's surface and onto the corneal/scleral junction (where the pterygium originates) whilst dark irises absorb the light.   PeterS Medico ----- Original Message ----- From: Peter and Mandy Temple To: 'Discussion of issues relating to Soaring in Australia.'

So wear a hat, and sunglasses and if you get dust in your eye rinse it out. I do not recall seeing anything suggesting that eye colour is a risk factor. If you blue eyed people want something to worry about you should worry about Age Related Macular Degeneration (especially if you smoke).
