“Another black mark against glasses purchased online is that, according to the journal Optometry, almost half of them don’t meet impact testing standards. This is an important requirement since the Food and Drug Administration considers all prescription glasses as medical devices. If the lenses shatter or crack easily, they can cause serious damage to your eyes.
Since most glasses have to be replaced every two or three years, it’s understandable why people are looking for cheaper ways to buy them. However, protecting and prolonging your eyesight is a worthy investment. If you’re thinking about buying your glasses online, consult first with trusted eye doctors in Durham, NC like those from the North Carolina Eye, Ear, Nose & Throat.”
