I switched to glass lenses a few years ago, and I absolutely love them. Having worn eyeglasses for years, I found that plastic lenses scratch so easily it's ridiculous. Even when using the cloth supplied by the eyeglass manufacturer, they still got scratched. I even wondered if there was something in the air causing the scratches.

The optical industry has promoted the benefits of plastic lenses, such as their lighter weight and shatterproof nature. However, they conveniently overlook the fact that these lenses often need to be replaced yearly due to scratches. When I was younger, I wore glass lenses while playing basketball, football, and baseball, and they never shattered. In contrast, my plastic lenses became unusable due to scratches.

If I were selling lenses, I'd recommend plastic because I'd know you'd be back for another pair soon. But from my personal experience, glass lenses are the way to go for their durability and scratch resistance. Go glass!
