Our eyes are the most incredible pieces of equipment and
they enable us to enjoy the world around us.
We have only two eyes so it’s vital that we take good care
of them because the passage of time, the ageing process and the
increased risk of medical conditions affecting them mean that they
may become less likely to satisfy our visual needs.
TAKE THE TEST
An eye test at least every two years (unless advised otherwise)
is very important. This helps to identify whether they need a
little help from glasses or contact lenses. For example, presbyopia
(loss of focusing power of the lens) usually starts in middle age
and most people notice that reading or focusing on objects close up
is not as easy as it was. It’s considered a normal part of
ageing and occurs when the eye lens becomes stiffer, larger and
less able to change its shape to focus. It is easily improved with
reading glasses.
A test also allows problems which can damage the eyes to be
detected and treated early. An example is glaucoma, a condition
whereby fluid pressure builds up and if left untreated can cause
blindness. The problem often goes unnoticed until permanent damage
has occurred. However, during an eye test, it can be identified so
treatment can be given and vision protected. Magnesium may help
improve blood flow and consequently vision in those with glaucoma
or at risk of it. Other medical conditions that can be detected
during a test, and which may cause visual loss, include diabetes
and hypertension.
EATING FOR EYE HEALTH
Diet plays a very important role in good vision. One rich in
antioxidants - vitamins A, C and E, beta-carotene, zinc, selenium
and flavonoids (found in red wine, green tea and dark chocolate) -
can help to counteract the effects of time and the environment on
the eyes. In fact, recent research from the Netherlands found those
people whose diet contains high levels of C and E, beta-carotene
and zinc are much less likely to develop age-related macular
degeneration - the most common cause of permanent blindness in the
developed world which affects around one in ten people over the age
of forty. It develops when the central part of the retina (the
macula) becomes damaged. Studies have also highlighted how two
specific carotenoids called lutein and zeaxanthin are needed to
help keep the macula healthy. Smoking increases the risk of
age-related macular degeneration and so is best avoided.
CLOUDING THE ISSUE
Cataracts are cloudy areas in the lens that are very common and
make vision unclear. Nowadays they can be easily treated by
surgical removal. Low calcium, smoking, excess UV radiation and
diabetes make cataracts more likely so the eyes need to be
protected from these. Lutein and zeaxanthin may help to reduce the
risk of them forming, as may vitamins A and B.
GIVE THEM A BREAK
Like any part of the body, the eyes need rest too. Whether
it’s close work or time spent in front of a computer screen,
if you are to avoid straining, then regular breaks are needed.
Don’t forget that like the skin, the eyes can be damaged by
UV radiation, so protect them by wearing sunglasses. Think about
protective glasses or goggles if there’s a risk of particles
of debris entering your eyes whilst you work or participate in
sports and hobbies.
