They are great until they break
I revised my review and added a second paragraph.<br />These are great in that they don't fall off when you lean over/look down. I've tried many different reading glasses. These are my favorites. The elastic frames have enough spring to them to grip your head. It's not enough grip to cause me any discomfort. I have purchased 1.5, 2.0 and 3.0 for use in various situations (computer, reading a book, working on electronics). Highly recommended.<br /><br />The problem: Where the lenses attach to the nose piece and the ear pieces is not strong enough. I have 3 pair of these now that have broken where the two little pieces go into the lens, either on the ear piece side or the nose piece side. Just a little too much force on them and they come apart. This needs to be improved.
