My girlfriend recently found out she has a genetic condition called Stargardt's Disease, which is a problem with the macula, in the retina of her eyes, and cannot be corrected with glasses. The doctor told her that she will be legally blind (20/200) or worse (up to 20/400) within 10 - 20 years. She absolutely loves target shooting, but the last time we went to the range, she had a very hard time lining up the sights with the target at 5 - 10 yards. Usually she's as good, if not sometimes better then me, but I've noticed her aiming has started to degrade over the past few months. I was thinking of buying a laser sight for my Walther P22 that I bought especially for her to try and help her with her aiming. I can buy one relatively cheap. I was wondering if anyone else here is, or knows anyone who is, visually impaired and what tips/tricks worked for them?
