Thanks folks - lots of interesting comments here - and no clear (sorry!) answer!!
>From my reading and gleaning these things seem important: 1. a light brown tint is frequently deemed best for gliding 2. dark tints are very bad - causing the eye to shorten their depth of field (being wide open) and suffer greatly from any flashes of light that manage to get in during thermalling, etc. 3. those who can use polarised sunnies swear by them (but usually folks who don't need a prescription - most people think that "you can't get polarised prescription sunnies"). Checks should be made with a borrowed pair to ascertain if you have canopy or instrument incompatibility. 4. cleaning is a certain way to introduce fine scratches 8-( 5. glass is the hardest to damage, but not if it is coated as is often the case in sunnies 6. a large lens is vital to reduce light hitting the eye 7. keeping light flashes from the side is important (Mike's wrap around tints should allow peripheral vision to keep working) Ol' Eagle Eyes are the first sunnies that I've seen that claim to address most of these points, especially being big, light brown, polarized and prescription. I am very reluctant to introduce an extra layer to look after, clean, and of course look through. Anyone happily using polarized prescription sunnies out there?? I, too, have mild astigmatism to contend with. Also detest that attitude amongst optometrists that you'll get used to anything! If anyone knows of an optometrist in Melbourne who is "aviation aware" I would gladly change to him/her! Thanks for all of your thoughts - most appreciated!

The optometrist suggested I try off-the-shelf polarised sunnies to see how I liked polarisation - fine. So he had some prescription polarised lenses made, and IMO they were unusable. They put uneven stains and colours across my field of view. The opto compared them to several other prescription polarised sunnies nearby, they all had what looked like stress marks... purplish tinted areas that became very obvious when crossed against another polarised lens. It seemed obvious to me that any glasses for flying should be optically uniform. The opto didn't agree and kept saying "you'll adjust to it". Just what the old brain doesn't need, one more thing to do while looking out! I didn't like the idea enough to fly with them... now I have the same thing with tint but without polarisation - no problem. Jason's answer of adding polarised clip-ons to prescription glasses sounds like a plan. -- Pete Siddall various GC _______________________________________________ Aus-soaring mailing list [EMAIL PROTECTED] To check or change subscription details, visit: http://lists.internode.on.net/mailman/listinfo/aus-soaring _______________________________________________ Aus-soaring mailing list [EMAIL PROTECTED] To check or change subscription details, visit: http://lists.internode.on.net/mailman/listinfo/aus-soaring
