There have been more than a few posts that address poor eyesight and the resultant front sight focusing problems. Here is my "economical" method of resolving the problem for anyone who may be interested. I bought two sets of stick-on lenses and placed them on a pair of safety glasses as shown.
The top pair are "upside down" to make the transition from the center section of the glasses to the "shooting lens" section quickly and without any of the distortion that would occur if they were mounted with the round edge facing down. The lower pair are used for normal bifocal purposes.
Note that the lens power required for the "shooting lens" is weaker than your normal bifocal lens. The reason being is due to the fact that you are focusing on your front sight which is now more than two feet (depending on your combined arm length, barrel length, and stance) further away from where your eyes focus when viewing things at your normal bifocal distance. If you use a "shooting lens" with the same power as your regular bifocal lens the front sight will appear blurred.
You can determine what power of stick-on lens you'll need by simply making a trip to the dime store and trying out different pairs of reading glasses. Find some object to focus on that is about the same distance away as your combined arm and front sight length. Close your weak side eye and keep trying various power glasses until you find one that allows you to focus your dominant eye clearly on the selected object at that distance. (By the way, I found the 1.0 power stick-on lenses that I needed on Amazon.com.)
Personally, I place aiming lenses in both sides of the glasses because I shoot using either eye. I am naturally right handed / left eye dominant but have learned to shoot using the same hand that corresponds to whichever eye I am aiming with. If you want, you can just put one lens on the dominant eye side and leave the weak side alone (this automatically provides you with the desired "blur" in your weak side eye to help promote "both eyes open" shooting). Another nice feature of these stick-on lenses is that they can be easily transferred between sides and between different pairs of glasses.
