TAKE CARE! SPOT THE EMERGENCY SIGNS
If you develop any of these problems, seek help immediately, if necessary by going to the Accident and Emergency department of a hospital or calling an ambulance.
As well as becoming less flexible, your lenses become yellower and more opaque as you get older. Clouding of the lens may develop into a cataract. At the same time, your pupils gradually shrink, so less light can get into your eye, and light tends to scatter more, increasing the effect of glare. What does this mean? Well, generally speaking, you need a lot more light to see clearly than you did when you were younger – and it needs to be uniform lighting rather than sharp pools of light contrasting with deep shadows, such as from a spotlight (this is fine for doing tasks but shouldn’t be your only light source).
Changes to the eye also reduce your peripheral vision, perception of colour and depth, and your ability to tell where one surface ends and another begins (contrast discrimination). It’s harder to see in dim light and to adapt to sudden changes in light levels. And if you are finding it harder to drive in the dark, you are not alone: night vision gets poorer with age. Here are some other changes to expect:
AMD – AND HOW TO TACKEL IT
Age-related macular degeneration (AMD) is a leading cause of sight problems as you get older. In one study in Bristol, UK, of 934 men aged 65 to 83, 9.2 per cent developed early macular changes, and 0.5 per cent developed full-blown AMD, over 17 years.
AMD occurs when the macula, the central area of your retina responsible for detailed vision, is damaged, causing blurring in the centre of your visual field and eventually a central blind spot. There are two forms. In dry AMD, yellow deposits called drusen build up in the retina and blood vessels become brittle, damaging the macula. in wet AMD, new blood vessels grow and leak beneath the macula, causing scar tissue. Wet AMD - which accounts for about 10 percent of cases - is more serious and progresses more quickly.
Once vision is lost in AMD, it cannot be regained, but as it affects only the central vision it never causes complete sight loss. People with AMD may have difficulty reading, driving or recognising faces , but can carry on with many day to day activities.
you’re more likely to get AMD if you smoke, are long-sighted or have a family history of it, but there’s much you can do to reduce risk:
If you spot the symptoms of AMD early, prompt action – mainly through dietary changes and stopping smoking – can help to slow any loss of vision. These are the most common signs:
Treatment of wet AMD may involve medications such as Lucentis to prevent new vessels forming or photodynamic therapy, in which a light-activated drug is injected to destroy the vessels.
OTHER SIGHT RISKS
your risk of serious eye condition increases as you age. but the damage is often limited by early treatment always seek medical attention for eye symptoms
DID YOU KNOW?
Smoking increase the likelihood of many eye-related diseases. It may treble your risk of macular degeneration a painless condition that eventually leads to loss of vision in the centre of the visual field – according to scientists Meanwhile, researchers at the University of found that smoking doubles the risk of uveitis (eye inflammation). Quitting can halt or even reverse the damage.
DID YOU KNOW?
Tears of emotion are chemically different from those produced when you get a speck of dust in your eye or if you peel an onion. Experts think emotional tears help to rid the body of stress chemicals.
ECCENTRIC VIEWING FOR AMD Losing your central vision due to macular damage forces you to use your peripheral vision. Eccentric vision is a technique that teaches you to use this residual vision more effectively to make everyday activities easier, including walking, reading, recognising faces and watching television. It is often combined with another technique called ‘steady eye’ for reading, in which you learn to keep your head and eyes still but move the page through the areas where your sight is clearest. Anyone with AMD or other major visual disabilities should ask their doctor for referral to a Low Vision Clinic. There they can be helped to make the best of their failing vision with eccentric viewing training and the most effective visual and reading aids.
