...So my concern is this, is wearing sun glasses potentially damaging my eyes worse buy making my eyes think it is safe, but if the glasses don't block all the harmful rays, then my dilated pupils and wide open eyes will actually receive a worse dose?Even thought maybe I should be wearing clear glasses with a UV filter and some polarization.I need more wind and less time to thing about stuff like this.
I think the cancer council of Australia took this into account when looking at sunglasses. They rate poorly the style that are open on the sides that let in might when the pupil thinks its darker due to the lense.
The CCA sunnies tend to be wrap-around to try and prevent this.
