These work well for those of us who need prescription lenses - just pop them over the glasses. They work well because of their simplicity. They are light enough that one barely notices them after a few minutes and they are straightforward, no complications that come along with 'flip ups'.
Not too big
Just what I hoped for.
purchased as a gift
and what a fantastic gift!! Came with a box, a case a cloth and as a bonus, a really nice pair of clip on sunglasses!!! Overall, i'm very pleased with this item.. and the recipient of the gift was as well!!
Decent for the price, but polarizing could be better.
Fairly decent clip-on sunglasses for the price. I didn't find the polarizing to be as good as the $180 pair of sunglasses I bought twenty years ago, but can't wear because I have to wear actual glasses now even when I drive. The clip-on is sturdy and they do flip up easily. I have rather large lenses, which these almost completely cover. They are quite thin, which is both good and potentially bad. I don't feel as though I have a second pair of glasses on face face, so that's good, but I am concerned about their durability long term.
