I switched from my regular glasses to contact lenses, so I no longer need big frames to fit over existing eyeglasses.
As I have gotten older, I now find it useful to have magnifiers incorporated into my safety glasses, for closeup inspection.
www.mcmaster.com has these, in a type that I really like. They are part number 2882T15 (for magnification of 2 diopters), which is in their online catalog on page 1685. These are probably like the ones mentioned above by solomon63.
Also, lower on that page are some frames that fit over existing glasses, for those who wear them.
Bob, for clarity, I think you will have better luck ordering glasses that are designated as "scratch resistant." This is because the scratch resistant coating also has some anti-reflection properties, so you can see through them more clearly. At least, that is my impression of the ones I have ordered.
McMaster has great illustrations in their catalog, so you can get a good idea of what you will be buying. Also, on page 1687, they have some add-on magnifiers, if you don't already have bifocals (part number 53635T305), and want them.
