Glasses aren't for people that are blind. There's no cure for blindness. It's simply for people who have poor eyesight. And yes, people would go blind if they did not cure their vision problems.
Well, if reading glasses were not made we could not see in life it would be a blur.
Nothing important occur.

Blahblahblah
We would not have a nice pool to Swim in
New technology would be invented.

No trade and commerce would have been possible.
A lot of things woodent have been invented. A lot of things wouldn't have been invented. A lot of things would not have been invented.
