Adjustable Headband Optical Glass Binocular Magnifier with 4 Sets of Intercheangeble Lens(1.8x-3.5x)

Thought it might help my Grandfather a bit more. He says he loves it, but does not make up for new eyes lol.

I was suppose to give this to my grandpa as a birthday present and it turns out you can't see through them. Bad product!
