I have been wearing eyeglassses for about 30 years and I have terrible vision. (-9 Diopters) I researched many sunglasses and thought Rudy Projects may be the sunglasses that I needed. When I ordered them, I allowed them limited flexibility in prescription. However, without permission, they severely downgraded my prescription so low that I could not even read signs 3 feet in front of me. The doctor gave a lecture me that I was asking for too much so I asked for my money back and, humiliated, I left.‎
