These clip on sunglasses will not win you any beauty contests, but if you measure your lenses and have a narrow bridge on your glasses they should work as described.  I bought these and&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Clip-On-Sunglasses-52Mm-Grey-Low-Rectangular-Frames-Affordable-Gift-for-your-Loved-One-Item-IA4L-SGC-161920000/dp/B0051POR6W/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Clip On Sunglasses - 52Mm, Grey, Low Rectangular Frames -Affordable Gift for your Loved One! Item #IA4L-SGC-161920000</a>, and the second set does not flip up, but look better on.  I've included photos of both.  Even though the second say they are 1 mm larger than the first set, the bridge is wider so they don't actually fit the lenses of MY glasses as well.  There is a gap on both lenses on the inside near the bridge.  It would be nice if when these companies were giving measurements they gave the length of the lens AND the length of the bridge.  Keep in mind the purpose is to keep the sun out of your eyes when buying a cheap clip-on... it would be nice if more fashionable glasses came with customized clips, but no such luck for me this time.  Oh, the second ones have a nicer case if that matters to you, but it creaks when it opens.
