I bough a similar one from China which just come with one pair of shade lenses. Then I found this, 5 pairs with the similar price. I am really happy with them. They are really stylish and convenient. The edge of the frame has two small piece of magnet, you just need to clip-on.
I put it in my car because I only use it when driving. It works and blocks sunshine as I expected. It's light weight and fits my prescription glasses well!
I like how it is interchangeable to 5 different shades, the clip on is magnetic and much nicer then regular clip on lenses.
This pair of glasses is exactly what I was looking for, it has a light weight with a sturdy quality.
I really enjoy these glasses, they look really great on me and all five of the different glasses are high quality material that do not break or scratch easily!
