Whatever the cause, visual changes should never be ignored.
Decreased vision is a significant threat to the quality of life.
Professional help is always indicated, but which professional to see is often a question. An optometrist is a doctor of optometry that specializes in evaluating the need for glasses and deciding on what prescription lens will provide the best vision. An optometrist can diagnose and treat many vision problems, although in some states, they can also diagnose and treat other medical problems. An ophthalmologist is a physician that specializes in eye disorders and is the appropriate person to consult for diseases of the eye. This list is not all inclusive, and the causes are not presented in order of likelihood.
