What are some of the common vision problems brought on by aging?

Some common problems include the need for assistance (eyeglasses) for close tasks and reading and an increased sensitivity to glare (such as oncoming headlights). Also eye focusing problems are much more prevalent as we grow older. Presbyopia a decline in the eye's focusing ability, is a common. condition associated with aging and causes nearly all of us to need bifocals or reading glasses by the age of 40 or 50. In fact, it is estimated that 94% of persons aged 65 and older require corrective lenses or other vision aids.

Other age-related vision conditions include cataracts, which are a clouding of the lens in your eye. Symptoms of cataracts may include blurred vision or distorted vision. In the early stages, cataracts can be managed with regular vision examinations by your eye doctor. More advanced staged cataracts can be effectively and safely treated through surgery. see section on Cataracts for more detail.

Glaucoma is a disease in which optic nerve damage occurs due to elevated fluid pressure within the eye. This damage can cause severe vision loss if untreated. Glaucoma can be treated with medications and in some cases, by surgery. However, any vision loss is permanent as nerve damage is irreversible. Since the majority of glaucoma patients do not have symptoms, regular eye examinations are important in detecting the condition in its early stages. See section on Glaucoma for more detail.

However, if they appear suddenly consult your eye doctor as they can be a sign of a more serious condition. See section on Floaters for more detail.
