I don't..bifocals..use the reading lower to 'see' the sights and then 'estimate' the target..not ideal but whatareyagonna do?You guys with bifocals, how do sight in on the front and rear sight and target all at once? I have to have one or the other blurry. terry
The Merit Aperture surely is a good device for sharpening the target up for precision shooting. I have owned several over the years and they worked to very good effect. However, they do not correct visual problems that are from aberrations within the eye. Before you buy one, simply take a piece of paper and poke a pin hole in it and look through the pin hole. Does the target/object you're looking at "sharpen" up by looking through it? Is so, it will help. If not, you have other problems that this device won't fix. It costs nothing to do the experiment, so try it before spending the money. There are many other things that can change due to age. You can start to get defects in the inner lens that every one gets with age....the lens loses its ability to flex/bend. You can also get pre-cataract clouding and defects within the lens due to pre-cataract conditions. Aging eyes happens to everyone and there are several things that can be done to assist with the resulting problems. Try the pinhole paper trick and if a Merit helps....great. If not, see an experienced eye doctor and see what they suggest. Getting a medical evaluation is reasonably inexpensive, about the same price as the Merit Aperture. Good luck with this.yes I realize you cannot focus on all three, I just wanted to know which was best to focus on first, that thing that goes on your glasses looks to be quite the help on focusing on your target. terry
