I was tired of buying dollar store glasses that would break after a month of use.  So I saw the Foster Grants and thought that, for $34.99, I would get decent use from them.  I was wrong.  About a week after I started wearing mine to work (retail manager, not very strenuous) the right lens fell out.  I popped it back in, it held for a day, then popped out again.  It would only stay put at most a few days.  I still continued to wear them, as I despise returning items.  Then, five days after my return window closes, the arm breaks right off.  I was carrying them in my shirt pocket at the time.  The lens are nice.  I like the multifocus feature, but they just did not hold up at all.  Very disappointed.  I will not re-purchase another pair.  At least $1 glasses are expected to not hold up.
