I give it four stars because three people (with presbyopia) wore them and got dizzy. The quality is very good. I thought there might be an issue with me. However, it was also present in two other people.

Very good protective glasses at an excellent price! Comparable and dare I say even better than other famous brands that cost 3-7 times more. The cost is such that you don't need to worry about where you put them in case they get scratched. Adjustable arms and they fit perfectly on my face. So good that I often forget to take them off!
