Magna-flip Clip on Flip up Magnifiers, +3.00 Power Converts Distance Glasses and Into Reading and Computer Glasses

I get a few hours a month to pretend to be a machinist. Much of that depends on reading old-school dials and verniers. And much of that means metal chips flying through the air.The metal chips dictate a good pair of safety glasses. The dials and verniers, for my old eyes, dictate some sort of magnification.These work just about perfectly over my safety glasses. The alternative is keeping a set of small magnifying glasses in a pocket, then swapping glasses every time I need to take a measurement or make a setting.As noted in other reviews, though, they ARE heavy. So, they could be better if each clip on came with cheap "croakies." Once I put the eyeglass holders on, these were PERFECT. I got to spend most of my couple hours machining, rather than switching glasses.

These clip-on magnifier glasses are larger and heavier than any I or my husband have ever owned. I don't know if it is because of the relatively large 3.0 magnification. I am going to look for a smaller and lighter pair.

They work well and are large to see thru but on the heavy side so pull my glasses down

The clip ons work well although they are a bit on the heavy side.I needed them for registration of printed products and these fit the bill.

Others have pointed out that these are bulky and heavy...all the better to magnify with! I love these!! I find these to be a much better alternative to the things you have to keep moving around to find the 'sweet' spot for reading. The ones that I received are very sturdy and fit my glasses fine, I don't have the thin wire frames. I can see where the weight could be a problem for those kinds of glasses. For me...these are great!

I was disapointed in this product and returned it. The lenses and very large and heavy. The lense shape is as large as any aviator type sunglasses I have seen and fairly thick glass. Once clipped on your glasses and if you move your head. your glasses will fall off. Maybe you could use a strap around your head to hold them on, but I was not interested in doing that.

I can’t use them because they are too heavy.

This items works OK, but the lenses are significantly larger than stated in the description or pictured and fairly heavy as well. They require a fairly stout pair of glasses to attach to, preferably a set with large lenses. If you need something light and compact, these are not your best choice.
