I have started wearing eye glasses and I am having problems using them while photographing. I have lost or broke two pairs of glasses already by constantly taking them off to look through the view finder. If you have my problem, how do you deal with it in the easiest way? I have seen ads for the Hoodman flip up eyeglasses for photographers, but have never seen a pair. They are expensive. Has anyone used these and can you give me your opinion of the quality and the ease of use. Thanks, John
