Everyone in my family has to wear glasses except for me. Do you wear them?
1_Wizard
Yes, but I only wear them for vision correction, reading glasses, and I wear sunglasses.

Seems like a good few reasons. What else do you know about them?
1_Wizard
They are traditionally known as eye glass or spectacles and they consist of glass of hard plastic which is mounted in a fame that holds them over a person's eyes, using the bride of the nose and the ears.

That's interesting! How long have they been around?
1_Wizard
I'm not sure when they were invented but some people wear safety glasses to provide eye protection against flying debris or for lab technicians. These glasses protect the sides of the eyes as well as the front.

Oh yeah, I've had to wear them in chemistry before. Aren't they closer to goggles?
1_Wizard
Yes, they are like goggles in that sense. They can also protect against visible and near visible light and radiation.

Oh wow, I thought they were just for debris!
1_Wizard
They are also worn for sports, for protection, such as squash.
