You know, DMC, there's this new invention that might be of use to you... they're two pieces of glass or plastic or polycarbonate, and they're set in frames that sit on the bridge of your nose, so they're right in front of your eyes.

Now here comes the remarkable part. These pieces of glass, plastic, or polycarbonate (called "lenses") are actually specifically made to make up for what you cannot see!!

There's another type called "contact lenses," but it might be too soon to talk about that. We'll save that for the next lesson. (I don't want to scare you!)
