Aged Eye Problems
There are many elder people who have crossed their 80s, have no problem with their eyes.But some physical changes that occur naturally often cause some problems such as cataracts and glaucoma with age.The older you get you need brighter light for everyday tasks such as reading, cooking, mending. Also driving a car can become a difficult task at night.
Following are some common problems
This usually occurs after 40/45 years of age due to a change in the eye muscles and lens caused by loss of elasticity, making reading more difficult. We can read only if the material is holded at arm's length. This can be rectified by having reading glasses with a convex lens. Every few years you will require slightly stronger lens to allow for the decreasing ability to focus.
A common complaint is of seeing tiny spots or specks that float across the eye, especially in bright light. They are normal and usually harmless but may be a warning of impending eye problems. If they become more noticeable or cause flashes of light, consult the physician.
Excessive tears are usually a sign of increased sensitivity of the eyes to wind, light or temperature changes. This complaint is very common in a cold wind. It can be minimised by wearing glasses, especially sunglasses. It could indicate blocked tear ducts (lacrimal ducts) or an eye infection.
This is caused by a reduced production of tears by the tear glands. It can cause problems such as blurred vision, itching or burning. It is easily corrected by using artificial tears.
Common eye diseases
Too much fluid pressure in the eye causes glaucoma and can lead to blindness. The rarer acute form (which causes sudden pain and visual problems) and the common chronic form (which slowly develops without early symptoms). All elderly patients should have eye tests on a regular basis, maybe every 2 years, but it is more important to have any unusual eye symptoms checked, it can be treated and blindness prevented.
The lens in our eye is clear and allows light to pass through it. A cataract is occured when the clear lens becomes cloudy or opaque and cuts down the light entering the back of the eye. Apart from deterioration of vision, there are no other symptoms. Cataract can occur at any age, it is more common in diabetics and those taking cortisone tablets. It is also hereditry. A modern lens implant (an artificial lens) can give excellent results.
Disorders of the retina, which is the photosensitive area of the eye can lead to varying degrees of blindness. Diabetes and other diseases can cause retinal problems. Sometimes the retina can become detached and seriously affect the eyesight. If this condition is detected early, it can be treated successfully.
