As we reach age 65, many of us will have some degree of cataract owing to age related changes in the chemical composition of the eye crystalline lens. As a result, the normally transparent lens becomes cloudy and vision becomes blurry. As much as the symptom is associated with cataract, blurred vision should not always be assumed that a clouded lens is the cause. Blurred vision may also result from other eye conditions and diseases, which, if not properly treated in time, can cause irreversible loss of vision. Proper diagnosis of any vision related symptom can only result from a visit to an ophthalmologist or optometrist, who can make a proper diagnosis a the first sign of a problem.
