How do I know if my eyeglasses Rx is correct?

[Yahir]

If there is something wrong with my prescription, how do I know? Every time when I look through my lenses everything distorted and sometimes I suffer headaches after several hours of wearing. Is it because my prescription is wrong?

An adjustment may solve the problem. You should not be noticing that drop, so take your glasses back to where you purchased it so it can be adjusted properly. If you have a plastic frame and it cannot be adjusted then the lenses should be replaced.

Go back to the places where you bought it and ask your doctor to check your glasses to see if they made correctly to your prescription.
