I have to wear my glasses when I ride. This season I wore glasses under a pair of Oakley O Frame goggles. Frequently the lenses of my glasses fogged due to low air circulation. I like the goggles but would like to use prescription inserts. I have talked with local optometrists and nobody seems to have an insert available for the Oakleys. I have e mailed Oakley and have had no luck with a response. Does anyone know of a company that makes inserts for the Oakley O frames or for a comparable goggle?
