I have a 1degree Pentax Spot Meter. I bought it new many years ago and haven’t used it for auite a while. Using it indoors or in the shade and everything is fine. But using it in bright sunlight I cannot read the numbers in the black box. I’ve put in new batteries bit no change. I don’t know of it is my eyes, I’m 82 with slight macular degeneration, or something else. I’m wondering if a foam eyepiece sould help like the ones that are used on professional film and video camers?
