I agree with Frank myself, when I was younger I hated wearing sunglass most of the time,
really cant rember why, the sun started bothering my eyes one day so i got a pair of good polarized ones and a whole new underwater world opend up to me, I saw fish and cover that I never seen before, on all waters, ponds, lakes, and rivers. Right now I wear a pair of Serengeti sunglass that cost me 500.00 (prescription), but my wife bought a pair of cacoons and I love them, thye slip over your glasses with out makeing you look like a dork lol. Thats my next pair, so I dont have to compltely switch glasses every time I need a view with out sunglass on.
P.S. make sure for the best underwater veiw to get a pair that wrap around your face
