LENSES & LENS CLEANERS

Flat plastic Fresnel lens. This flexible magnifier is 7-1/4" x 10-1/4" and only about a millimeter thick. It is great when you need to scan a list, read a book, start a camp fire or just want to embiggen something. You can see most of the page without moving the magnifier which makes it great for reading. Only about 1.5 power, but that can make a huge visual difference. Nice piece at a very nice price.

Thick, but very desirable, like a nice fat slice of salami, these negative meniscus glass lenses are 55mm dia with a focal length of -169mm (think: reduction). Great for artists and crafters. Edges might have some slight chips, but that's surplus for you.

These white microfiber cloths are larger, at 6" x 7-1/2",  and thicker than usual. Made for medical equipment (so you know the quality is excellent), they're dandy for eyeglasses, lenses, computer screens and other electronic equipment. White with a dark blue edge (with a small logo in one corner) they're actually attractive and could double as pocket squares. Bundled by the pair so you'll get (6) cloths in our Pkg(3), or try our super low 20-pair price.

These standard-size 2” x 2” slides in tan plastic frames are polarized despite not having an opinion on anything. It’s the polarizing filter in the lens that makes them polarized.
