I wear glasses, also called eyeglasses which are plastic lenses mounted in a frame and worn over the nose.
I used to wear them also. When were they invented?
They have been worn for hundreds of years. Mine are used for vision correction.
Oh wow. What type of doctor should I see to get glasses?
You should see an optomologist. Sunglasses allow better vision in bright sunlight.
I really should get a pair of sunglasses also.
While you are at it pick up a pair of safety glasses to protect against debris when working with tools.
There are so many different forms of glasses. They have so many uses.
The military uses ballistic eyewear to protect against projectiles and fragments.
