Hello, dear naco. You said you can not distinguish the anti prescription sunglasses. let me help you. It is very important that before you purchase prescription sunglasses, you will need a prescription. After this, you should know that the cost of different coating like anti-scratch, uv etc. can nevertheless increase the price of the pair. But some of the online stores offer these coating for free. You could have a try.
