In this case, is it better to wear the glasses or not?

I recently found out I have astigmatism, my vision becomes a little bit blur at far distances. The doctor told me that as I stay too much time in front of a computer reading in a close distance, probably the contraction and relaxation of the eye muscle bended it in a plastic way.

I’m studying optics. So my understanding of this is that the lens in my eyes have a variable power, or a variable focus. At very far distances the muscles are relaxed and the lens have their smallest power. In close distances the muscle contracts and the lens get their greatest power. I assume my eyes muscle got used to contract so much that the lens got plastically bent and the power when they are relaxed increased. So I’m using divergent cilindrical? (I don’t know how it works for the astigmatism) glasses that will make the combination of glasses +eye curvature get back to what it was before and make me seeing far objects again.

My only concern is: What about reading things close to you? Is it better to use the glasses or not? Because in my understanding if they are really divergent glasses I would have to contract even more my eyes muscles to get the lens to focus in a close object.

PF really does not and can not give medical advice. Please get help from an ophthalmologist/optician. So we are closing the thread.

I believe your understanding about what is going on could profit viewing:
