I ordered two pair of the polarized glasses, one for myself, the other for my sister. We both think the glasses are very good; my sister, however, requires prescription glasses, (something I'd forgotten during the first order) so I ordered these inserts for her. I've not spoken with her since she ordered the lenses from her optometrist, but as pleased as she was with the sunglasses themselves, I'm sure the inserts will work well for her.
