4.0 out of 5 stars
pay attention to the difference between diopter and magnification,
Amazon Verified Purchase(What's this?)
This review is from: Carson Optical Clip and Flip Magnifier (Tools & Home Improvement)
Note these are 1.5x. That is magnification, not diopter.
If you go to Walmart and look at their reading glasses, the values given there are in diopters. I knew I needed +1.50, but didn't know the difference between magnification and diopter, so got these. These are 1.5x, which is +2.25 diopter (a little too strong for me). Now I've learned. A magnification number has an "x" at the end of it. A diopter number has a "+" in front of it. Reading glasses are usually given in diopters. Magnification = (diopter / 4) + 1 So these are actually 1.5625 magnification, to be precise. But again, for reading glasses, the magnification is a distraction from what most people are looking for: diopters.

Excellent clip ons for work,

I have tried bifocals, but they gave me a headache every time. These are perfect for close work in the shop.
And to make some clarification, the 2.25 stamped on the bridge of the clip-ons is the diopter of the lens which is equal to 1.5x magnification.

Using clipons in addition to my regular eye glasses, while on the computer, works great!
