The doctor is recommending that you see an MD eye doctor; the MD eye doctor will tell you what is going on with your eyes. It is very hard for anyone to give you a diagnosis, without examining your eyes.
Good luck to you.
You are correct I saw an optometrist. What might be the causes of this problem?
It means you need to see a MD physician ophthalmologist for an evaluation. Find one at www.aao.org I suspect you saw a non-physician optometrist.
