When shooting a hand gun my wife who wears Bifocals is having a terrible time holding a sight picture while being able to see a 25 yard target. The top of her glasses are for distance the lower for her close up vision. At reading distances around 18" she does not use her glasses at all. It has been some time since she has been active in shooting and she was very disappointed to find this out last visit with me to the range I just joined. She used to be a VERY active in blackpowder shooting competing in trail walk and bench rest competitions almost twice a month. Has anyone here any experiance with a similar problem and know of a way to correct this. Without her glasses she can not pickup the sights or the target.
