Eat Your Greens!

Thursday, July 23rd, 2009

You might think that unless you want muscles like Popeye, it’s not worth eating spinach, but let’s have a rethink on gorgeous greens, because there’s more to them than meets the eye…..

Various institutions, including Manchester University, have been looking into the effects of diet on eye diseases. Prevention is obviously better than cure, and researchers have been trying to find ways to protect the structures in the eye, as presently there are no cures for diseases such as macular degeneration.

Age-related macular degeneration or AMD is the leading cause of blindness in the developed world,  it is a disease that adversely affects the macular, the portion of the retina responsible for central vision, and our ability to see fine detail. In the over 75 age group 12% of men and 29% of women are sufferers. The cause is presently unknown, but we do know that smoking is a factor – so give up now! Never think it’s too late – you’ll halt the disease as soon as you stop.

Green veg such as Kale, spinach and broccoli contain Lutein, a substance that helps to form macular pigment, a pigment that stops the development of AMD. You can take supplements to protect the eyes, look for those that contain Lutein and zeaxanthin, and preferably zinc, which is also necessary for visual pigments. The retina contains one of the highest concentrations of zinc.

As we’re all living longer, and living that life to the full, it makes sense to look after one of our most precious senses. Your Mum was right – eat your greens, and you might also get the muscles to match your super sight!

See Your Hundredth Birthday!

Even if you’re a fitness freak or a gym bunny, the one aspect of health you may not have thought about is looking after your eyes. We all focus on a balanced diet, moderate exercise, and looking after ourselves, but do we pay attention to one of the most important organs in our bodies?

Keeping your eyes healthy is really a matter of prevention, and a few simple steps can go a long way towards preserving your sight and general ocular (eye) health. A vital step is to have regular check ups with a qualified Optician, also called an Optometrist. They recommend tests every two years to check your eye health, tell you if you need glasses, and will even pick up some general health issues too.

If you smoke – give up! Smoking is a factor in the eye disease Macular Degeneration, and as soon as you stop you are halting any damage. Macular Degeneration causes loss of central vision, which means you won’t be able to see to read or drive. It may also be a factor in formation of cataracts.

A good balanced diet will obviously help your general health, but can also maintain healthy eyes and vision too. Natural carteniods, found in green leafy vegetables have a positive effect on the retina and therefore protect against Macular problems. If you don’t eat a wide variety of fruit and vegetables you might consider taking a supplement to maintain eye health.

There are many supplements on the market. Ingredients to look for are antioxidants, zinc, selenium, Vitamins A, B, C, and E, Lutein and Zeaxanthin. Antioxidants and zinc reduce the risk of Macular Degeneration. Selenium and the Antioxidant vitamins A C and E encourage mucus production, which keeps the soft tissue around the eye – the conjunctiva healthy. Vitamin C may also protect the eyes against cataract formation. Vitamin B complex is vital to healthy function of the Optic nerve. Lutein and Zeaxanthin occur naturally in the retina, the light sensitive layer that lines the back of the eye. These nutrients protect the retina by absorbing blue light, which can damage the Retina.

You may not have realised that keeping your body fit keeps eyes fit too. It improves oxygen levels in the eyes, and a recent study has shown that children who play outside and therefore focus at long distances are less likely to become myopic (short sighted) They also benefit from being out in natural light too.

If you wear prescription glasses then take good care of them and ensure that they are kept clean and up to date. Talk to the Dispensing Optician when you visit your Optician’s practice to make sure that you have UV protection if necessary, and the correct tints for your needs. They will also help you with protective glasses for sport or at work.

Looking after your eyes takes very little but reaps huge rewards. We’re all living for longer – won’t it be nice to actually see the cake at your hundredth birthday party?!

Sun Block For The Eyes!

Saturday, May 2nd, 2009

Summer’s definitely on the way, hopefully we’ve seen the last of the Winter snows. As you’re slapping on the factor twenty and enjoying the Spring sunshine, are you thinking about your eyes too? Few people know that exposure to the UV rays in sunshine can increase your risk of eye diseases like cataracts and age-related macular degeneration.

The amount of UV that reaches you can vary at different times of the day, with the height of the sun, altitude and cloud levels. You’re more at risk in hotter climates, and near water where rays are intensified by reflection, but even on a cloudless sunny day in a UK city maximum exposure time should be no more than fifteen minutes.

The best protection for your eyes is a pair of good quality tinted lenses, whether prescription glasses or non prescription sunglasses. Make sure they have a 100% filter to stop UVA and UVB. Wearing lenses that don’t offer this puts you in more danger than not wearing glasses. A dark lens will make your pupils open up, allowing even more UV to pour in.

A hat with a big brim and keeping to the shade will shield your eyes further, and the fit of sunglasses is important too. A shape that hugs your face will stop the sun from getting in, and go as large as you dare for maximum protection. At last – a fashion that’s both cool and sensible!
