They just don't see very well. There are millions in the world who need glasses, but can't get them. You can donate frames to help get glasses to people who aren't able to have them.
Eyeglasses changed history because now people could see better.
it changed the world by helping people improve/help their eyesight, so they can see better. also, because of how many people use them & how popular they are today. they have grown into a giant thing. Katherine Blodgett made the eyeglasses that we use today; it is more modern than others. The eyeglasses she made were non-reflective! So, it didn't glare. Which was a good thing. And, plus, without them, half of the people on this Earth wouldn't see as clearly as other people. :)

The best type of cloth to use for cleaning eyeglasses is a microfiber towel. These towels allow the glasses to be cleaned without it scratching the surface of the glass.
The best place for inexpensive quality eyeglasses is over the internet. I was stunned at the prices compared to any Optical retailer.
