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.

Forget watchmaking, you could write "A Tale of Two Cities" on a piece of tortellini with this triple magnifier visor. Magnifies from 1.8X to 4.8X. Has a flip-down 1.9X lens and a flip-down 4.5X loupe, plus dual white LEDs in a pivoting mount, powered by (2) "AAA" batteries each, not included. The whole thing is in a black plastic visor, 7-3/4" wide x 5-1/4" deep with a flexible plastic strap and adjustable dial control. Opens to 9" max dia, and has coated acrylic lenses. Now then: It was the best of times, it was the worst of times....

This very good-optical-quality 3X magnifier has a 3” dia glass lens set in a 7-1/2” long traditional Sherlockian-looking rubberized handle. In black with French blue accents for stylish sleuthing. Plastic and rubber body is shock resistant.

Steampunk alert! Also…model and jewelry maker alert! This pair of 10X acrylic doublet loupes is mounted on black eyeglass frames and flanked by LED lights powered by (2) included CR1620 button cell batteries. These are for close work only, from 1" to 1-1/2", and can focus only one lens at a time (not both on the same object) so if you’re a steampunker looking for a new accessory, plan on perching this rig on your pate or chapeau.

This XL magnifier measures 3-3/8" dia with a 5" long handle, all rubber coated. Glass lens is 1.5X and surrounded by (3) bright white energy efficient COB LED strips that run on (2) included "AA" batteries. Tap-on, tap-off switch. Good for everything from reading to looking at bugs and such.

Excellent quality 1-3/4" dia magnifier on a gold- or silver-colored, thin 36" chain with clasp. Package calls it 5X but our magnification guru says less than that at optimum focal length. Perfect for wearing to formal antique shows.

Just let me whip out my LED Double-Multiple Jewelry Identifying Magnifier with 11mm and 22mm acrylic lenses, at 10X and 20X magnification. (Don’t believe its claim of 30X and 60X. The mismarking is why you’re getting it cheap.) Has (2) super-bright white LEDs that run on (3) button cell batteries (included, with a spare). Use it for home, office, hobby, finely detailed work, model or jewelry making, watch repair, crafting, and yes, for looking at someone’s diamond. Comes in a sturdy oval case.

This folding magnifier has (2) glass lenses that can be used solo or in tandem. Each is 1” dia and 7.5X magnification, and together they’re 15X (which you just did in your head). The hinged lenses slide into a black plastic teardrop case that measures 2-1/4” x 1-1/2”. Like a giant jeweler’s loupe. Super-handy, powerful and as portable as they come.

A nice 3X loupe, 2-3/8" dia, that folds into its own 3-3/8" x 2-5/8" tear-drop-shaped plastic case, and it's only 5/8" thick, just right for sliding into your pocket. Pay no attention the "6X" markings on the package-if mistakes didn't happen, we wouldn't be in business.

This 10X folding loupe in black plastic and aluminum has a pair of very bright white LEDs next to the 25mm lens. Runs on (3) button-cell batteries, included, and has a tiny wrench to help you replace them. Loupe and wrench stow snuggly in a foam lined plastic case. When folded, it looks like a standard coach's whistle, or a really big apostrophe.
