In the backs of old comics they used to sell amazing devices, the X-Ray Specs were one of them. The magic glasses supposedly let you "See the bones in your hand, see through clothes!"
Not really an X-ray system these were a diffraction grating that blurred the outline of the viewed object (the transparent flesh) and created a darker inner region (the bones)
In the real world similar, but much bulkier and much more expensive systems include:
To make people see better.
Eyeglasses changed history because now people could see better.
Eyeglasses are made to correct the vision of people who can't see well. They work by changing the way light enters our eyes so that we can see better.
I don't see why not... most people do tan naked.....
UltraViolet. It's an invisible light that can't be seen with the naked eye. Even with glasses.
Eyeglasses help people see more clearly, however they are not for everyone. Only people with vision problems wear eyeglasses, such as myself. Because people have all kinds of different vision problems different prescriptions are assigned to the persons specific needs. If you wear glasses that don't belong to you are are the wrong prescription you will damage your own eyes and you yourself will require glasses.
There is the belief of how you can see another person naked if they are family or in a relationship. It mostly all depends on how old the person is, and who it's with.
so people know they cant see, also they cant see so they dont know where to move their eyes
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. :)
they will see things more clearly, not mistaken stuff , or if you HAD bad eyes not run into things.
Well there is but you do not see any part of the body
Eyeglasses work by bending light rays in the eyes of those who can't see well so that they reach the back of the eye properly (called the retina). When the light rays reach the appropriate part of your eyes you see better.
