They're cheap fashion glasses. Comparable in price to sunglasses purchased at a discount store.
The one downside is upon dropping them a lense popped out. In fact- both of them popped out at some point. I was able to push them back in, but I know I will need to superglue them in the future.
I know some people inquired if they fit an adult- well- they fit me and I'm an adult. However, we all have different sized heads. I was able to take the measurements from my daily use glasses and compare them to the measurements provided by the seller to determine if they would fit.
