Can dry eyes decrease my vision?

When my eyes get really dry I get more ghosting, blurry and overall poorer vision. No doctor said I had severe dry eye but I do kinda have a "rough cornea." Lubricant drops do not stop the bad vision but may help prevent it from getting drier. If I were to totally eliminate my dry eye would that likely fix my vision problems? It seems like I could have "Abberations" on my cornea but its kind of odd that it has gotten a lot worse over the past few years. I have updated my glasses recently so I know it has nothing to do with that. Also I notice when I just get new glasses that are a little strong on me I see a lot better than if its just right. BTW I'm planning on getting RGP contacts and hope that will help a bit but I'm worried that dry eye could be the cause of my ghosting vision. I never remember having these vision problems before high school of course I might not have payed attention either.

Sister Siter Dee- Yes I do have astigmatism and myopia and yes I have been prescribed eye drops. I told the doctor it did not work and he hasn't been helping me out since he is too far away for me to really check up. Eye drops don't do a lot.

Dryness can definitely decrease your visual acuity.

Well, RGP lenses can definitely help if you have an irregular cornea. You don't have Keratoconus, do you?

The dry eye though--is that a guess or you've been told you have dry eye by your doctor? If you have been told to use artificial tears and they don't help a lot, make sure you let your eye doctor know--there are other things that can be done for dryness.

I assumed by some things you say that you are nearsighted with astigmatism, is that right?

Yes it can. Aslo can cause infections. Use artifical tears if necessary.

yes -try Systane and follow up with an opthalmologist.
