If you find somebody saying that his or her prescription glasses are scratchproof, please don’t believe him or her. Mostly in these cases, it is only a marketing gimmick implemented by the company or the retail store.
However, one thing should be remembered that this coating would not protect the glasses from a scratch if the glasses fall on a hard surface, but they will surely minimize the small scratches that may occur in the daily use, so that your glasses remain clearer for longer. But it depends on how carefully they are used.
Most of the online glasses stores buy branded glasses directly from the companies. No doubt, some of them sell the fake models. But those who really buy from the companies can give them at low cost because they ignore the middlemen. Moreover, the online stores don’t have to pay for the expensive high street properties to sell the designer glasses.
