What different lense types have you found to be good on hazy or dark cloudy days?
It seems that regular sunglasses are usually too dark, and some colors on the plane tend to disappear. I'm blessed with somewhat less than perfect eyesight, so I'm looking for something that is available in a prescription lense.

Has anybody had any luck with the yellow lense used in shooting glasses? I'm not certain if they would offer any uv protection staring at the sky, so I'm a little hesitant there. Maybe driving glasses?

Any suggestions?

Thanks,
Larry Caldwell
