There are several things that could cause this type of vision
change, and there may be things the ophthalmologist can do to improve your vision
depending on what is happening.
I can't think of a better option for you than making an ophthalmologist appointment now for an exam. Be sure to tell the doctor when your symptoms began, what vision problems you have, and bring a list of any other health problems as well as all medications, vitamins and supplements you take.
