I don't know if this will work for you, but this is what I did. I found this on another forum, looking for a solution of having to use bifocals.
(Bifocal/front sight problem solved!
I wear bifocals. But I take them off when shooting; otherwise, I've got to tilt my head way back to bring the front sight into focus through the bi-focal part of the lens of my glasses. Bummer. Then I came across an interesting product: stick-on bifocals. I bought a set (paid about $16, but since learned they are available for much less). The kind I found are called "OPTIX Stick-on Bifocals". I'm not associated with this company; there may be others.
Here's what I did.
1. I went to the big ChinaMart and put on pairs of their reading glasses right over my glasses, until I found a pair that let me read comfortably through the upper part of my lens, figuring if I could read print, I would also be able to see the front sight. I noted the magnifying power for that pair of glasses. That comes as a + 1, or +1.5, or +2 etc.
2. Back home I ordered the magnifying bi-focal lenses, in my case a +2.50. They are the familiar half-moon shape.
3. When the lenses arrived, I carefully scissored out a piece about 3/8" wide and 5/8" tall and shaped it as best I could to conform to the curve of the frame in the upper-left corner of my right-eye lens. It is not a perfect fit, but it turned out not to be critical.
The garage is where I dry-fire--no ammo available there. My firing stance is 30 degrees off-center and to the right, so I naturally tend to look through the left side of my glasses. As I brought up the weapon the first time, my right eye found that magnifying piece immediately; there was the front sight clear as could be (and the target fuzzy as it should be!). Wow!
Problem solved.
Oh, and that little piece of lens is no more intrusive when you're looking straight on, for example as in driving, than the bifocal at the bottom; I got used to it immediately. And so far nobody, including She Who Must Be Obeyed, has noticed it.
Hope this is helpful. )
These stick-on bifocals have worked great, if all you wear are reading glasses, you can use these on your regular shooting glasses, they are hard to find though, everywhere I looked they were sold out, I ended up finding them on ebay, they were $24. I am still trying to figure the perfect spot for them. The good thing is that you can take them off and reapply them and cut them into the shape that works best for you. With the two lenses that I got, I figure that I can get about 10 pieces out of them. Thats alot of replacements and should last a long time. This is what they look like,
I just used one and cut a small portion and put it on the inner portion of my glasses of my shooting eye, I am trying different positions. I read that some have glasses made with the bifocal on top. That is where I will try them next. I have a backup pair of old glasses that I am using them on. These will be my range glasses. I hope this can help you or anyone reading this
