    Your Sight As You Age!!!

    gradual falling off in sight used to be accepted as a normal part of ageing. This is true in some ways. For example, you will be less able to focus on close objects as you get older. Also it is normal to need reading glasses as you go past 35-40, especially if you are long-sighted to start with. However, most people should continue to have good eyesight into their 80's or 90's.

    If your sight seems to be failing, it is vital to see your doctor early on. This is very important with a sudden loss of vision. Often the problem affecting your vision will be curable as long as you seek help quickly.

    Common eye problems
    Floaters

    These small dark floating marks are usually harmless and so are more of a nuisance on bright days. However, if they change or you get bright flashing lights at the same time, seek help immediately, as these are warnings of serious problems.

    Cataracts

    Cataracts are a cloudiness of the lens in the eye. 65% of 50 year olds have them but you may not notice until the cataracts are quite severe. They occur as a result of ageing changes but are commoner in diabetics or after trauma, as well as in those on medication such as steroids.

    Once the cataracts get so bad as to affect your vision, you may want to visit your doctor to get his opinion. Cataracts cannot be managed by drugs, but surgery is now highly specialised and effective. This involves taking out the affected lens and possibly replacing it with an implant.

    Glaucoma

    Glaucoma causes an increase in the pressure in the eye. The retina and nerves are damaged and sight gets worse. You may notice pain and redness or just that you have difficulty seeing.

    There are various causes, some of which run in families, but it is manageable. Treatment includes drugs to lower the pressure in the eye and surgery to help decrease the fluids in the eye drain and relieve the pressure.

    Macular degeneration

    This is an ageing change in the centre of the eye and causes a slow loss of the central vision. It is not actually treatable, although complications, such as the retina detaching, are.

    Vascular disease

    As with the rest of the body, damage to the fine blood vessels in the eye can cause sight loss. Certain conditions, such as diabetes or high blood pressure, make this damage more likely. It is important to keep chronic diseases well managed in order to protect your vision. This may be difficult, especially if you may have no symptoms from a long-standing disease.


    Medication

    Some medicines may affect your vision. For example, malarial treatments and steroids can cause problems. You need to check whether the medication you have been prescribed has any side effects. Smoking, high alcohol intake and drug abuse are known to speed up several disorders of the eye.

    What can you do?
    If you notice your vision worsening, it is important to go to your doctor or the local eye hospital. The eye is a very sensitive organ and prolonged problems can cause severe visual loss, if not blindness.

    How to improve visual problems
    Good lighting is vital for you to get the best of what vision is left. Generally, you need brighter lighting as you get older and normal light bulbs are better than tubes.
    Low vision aids, such as a magnifying glass, large print books, talking books and Braille stickers all help with your day-to-day living.
    Mobility training and guide dogs are a valuable source of help to many with sight problems.
