There is a difference in the lense quality of glasses.The first one is glass which is the most scratch-resistant material but it is heavy and easy to break.The second is plastic which is lighter and hard to break.The third one is high index which is lighter and thinner.This kind of lens making eyeglasses more fashionable and comfortable.

Yes. There are several kinds of lens materials. One is glass lens which is the most scratch-resistant and provides the clearest vision. But it is the heaviest of all the lenses. The second one is plastic lens which is lighter and more shatter-resistant than glass. The third one is polycarbonate Lens which is also a light material. And it is more durable than plastic and glass. The last one is high index lens. If you have strong prescription, the high index will make your lens much thinner, lighter. But it is more expensive.
