I actually bought them to wear over my regular glasses for use out in the sun and night time driving. Unfortunatly, they're not designed for that kind of wearing. But, they are made well and the magnets are strong enough to keep the lenses on the frame. If you wanted you can even put one over the other.

The clip on sunglasses are actually magnetic and will attach to your existing glasses as long as they are metal and have a curve to them. If you don't need to wear glasses at the same time then these are great and will work.

I decided to give this as a gift to my Girlfriend. I think it's important for people to have it if they have any type of vision issues especially at night. So the glasses are able to come together magnetically so that you can look stylish at the same time. The yellow glasses helps a lot with his night driving because he does work late nights as a security guard and I want to make sure that he's safe while driving and while at his post. I asked him if he liked it he said yes he really likes funky gadgets such as these things. I may even get another pair for myself because I do have a little problem seeing certain things at night I have to really concentrate when I'm driving

its worth buying this product for this Price. polarized and night vision Frame works great i Loved it. I used it through a day there was no discomfort for me…. For this price its a great product to buy.
