Find the Right Reading Glasses

Long time ago reading glasses were made only of glass.

And, as far as eyesight is concerned, glass is great. However, it’s heavy, and reading glasses of glass can break.

So, mid-century, along came plastic. Plastic doesn’t break and plastic is lighter. Plastic became popular and fast.

Progress being what it is, we have added a third contender – High Index. They are thinner, more expensive and easily scratched or broken.

Which is best for you?
