Firstly, if you want to take the reflections off the water, they have to be polarised! Photochromic are good because they lighten in low light situations,(early morning, you still want to see under the surface without reducing the available light) Then darken as the UV increases.But as far as I know, are only sucessful in glass! Glass lenses don't scratch as earily as CR39(plastic)But they do break and are much heavier. Although Polarised glass is laminated and much safer. Brown lenses have better haze penetration than grey, and being "Yellow" have good shape definition also. Polaroid lenses are polarised, mass produced,and inexpensive. They do the job! Bolle' on the other hand are optical quality lenses and much clearer with no distortion!!! The brand is a personal choice!! The higher the price, the better the Quality. To a point. Brand name comes into it!!!!!!!
Perscription Polarised lenses have been around for decades,both in brown and grey, take your Rx to any dispensing outlet or optometrist and talk to them, These are also the best place for advice no non prescription sunnies also!
