My eyes are getting older and I need to use readers. So, I needed some shooting glasses that had either a prescription or magnifier in them. Ended up purchasing some top focal glasses from SSP. I have to say, these are awesome. The magnifier is in the upper portion of the glass and so when you bring your head down on sight, now I can see the sights in focus. Gives the target just a minimal blur at handgun ranges. Great product.
