Vital Statistics

Friday, July 9th, 2010

As professionals we take serious notice of all of our trade journals and the press to give us up to date information about every aspect of our working life. We need to know about new trends, advances in technology and health, and items that may appear in the National press and we’ll be asked about. Surveys are always of particular interest to us, because it’s fascinating to know what the General public are thinking!

A cause for concern was a survey which claimed that 90% of the public are not aware that UV rays are as dangerous to the eyes as they are to the skin. The raised incidence of skin cancers has led to a vast amount of publicity regarding the dangers of unprotected UV exposure, but the message does not seem to have filtered through that several eye diseases can be triggered by UV. 42% of people surveyed did not know there was anything they could do to protect their eyes – so if you’re one of them here’s some information – wear kite marked sunglasses whenever you’re out in the sun, making sure they offer 100% protection against all forms of UV. This can protect your eyes against developing Cataracts, Macular Degeneration and Pinguecula. If you’re ordering new specs you can add a UV filter, even to clear lenses, for maximum protection.

We were surprised to read that although 79% of people know that they should have an eye exam every two years, only 60% actually do have examinations that regularly. For many patients the test is free, and it’s an opportunity to check your eye health and many aspects of your general health as well as sight. When 90% of us fear losing our sight over any other sense, it makes sense to keep up to date with this quick and simple part of your wellbeing and good health routine.

The next worry was a survey saying 18% of people under age twenty do not wear their prescribed glasses. While this won’t cause damage long term, it will cause eye strain short term, and at a time when exams and studying will be causing stress even with perfect sight. So make sure your children choose fashionable frames that they will enjoy wearing! Only 3% of under 18s wear contact lenses, which should be a viable alternative to specs wear. In other age groups the uptake of contact lenses is 26%, so try not to let constraints of time and money prevent your teenager from trying contact lenses – a few appointments will sort their sight correction out, for less than that new pair of trainers that they think they can’t live without!

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!

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!
