If I Wear other peoples eye glasses can it mess my eye vision up.?

For example my friend lets me borrow his glasses during the class because they help me see can his glasses mess up my vision up worse

over a period of time - yes you will damage the muscles that focus the lense in your eye

duhh..

I have heard that this is not good but more so I have just heard of the headaches it can cause especially in the case of a prescription being too strong I would be careful anyway you only have one set of eyes!

Well, if you wear them long enough, your eyes will adjust to it, which will alter your vision dramtically.
UNLESS you have the same type of glasses.

Yes if you wear them enough.. How bad it can harm your eyesight depends on how different his prescription is from the one you need.

I'd just go and get my own. If his glasses are helping you see, then you definitely need some of your own with the right prescription.

if you have healthy eyes you will be ok.

if u need glasses u should see ur eye doctor so u can get fixated glasses....ur eyes hurt and u have a headache beacause ur eyes are trying to adjust....its like reading in the dark, ur eyes try to adjust witch makes them hurt and u eventually have bad eyesight.....so ya....

Umm let me think about this........ YEA DUH!!!

Not likely. You might experience headaches or eye strain, but if the glasses help, you should go see an eye doctor and get your own.

No. The worst thing that can happen is that you get a headache. But if you find them helpful, why not get some of your own? Then you'll be able to see perfectly.

Please ignore this nonsense about minus lenses causing more myopia. If it were true then we could cure hyperopia with minus lenses. It's not possible.

If you can see better with your friends glasses, that is a sign that you can be helped by a correct examination and prescription of your own.
Disregard advice given by unlicensed people.

Yes it will strain/damage the muscles that control your eyes!
you wouldn't take someone else's heart medicine! Please do not self diagnosis or self-prescribe!
