Keep Clean and Beautiful!

Friday, November 5th, 2010

When we talk about eye health we are of course mostly concerned with the inner workings of the eye, and our visual system. Regular eye tests, eating a varied and multi-coloured diet, and giving up smoking can all have a positive effect on your sight and lessening your chances of serious eye disease. But what about the all important, delicate area that surrounds the eye itself? Let’s take a moment to check that we’re doing all we can to keep this healthy too.

The first and most obvious topic for discussion is cleanliness, which contributes hugely to eye health. The eye lids and lashes require lots of glandular secretions to keep them moist and working at their optimum. So this area needs to be kept clean to avoid blockages of the glands, which can lead to styes and other forms of infection. Always remove make up at night, however tired you are, using a gentle eye-make up remover lotion. Note the use by dates on cosmetics and discard them if you get an eye infection. Keep make up brushes clean by washing regularly in mild shampoo. Treat the delicate lid area very gently, using your ring finger to apply moisturisers, and don’t drag the skin. This is a health and beauty tip which will help to stave off the dreading wrinkles for as long as possible!

Our tears, combined with the blinking action, keep the surface of the eye ball lubricated and sterilised. If you’re in a dry atmosphere, blink as often as possible to keep the eye clean and comfortable. At the very first sign of an eye infection, take contact lenses out, and consult your pharmacist or GP for advice. If the lid area is sore, red, hot, or uncomfortable, then you may have a condition called Blepharitis, an inflammation of the lid margins, or a stye. These need treatment, so talk to your optician or GP.

So a little extra time and care, and good hygiene regimes can help you to avoid these problems, and stay more beautiful – always worthwhile!

VDU Specs for You

Sunday, May 23rd, 2010

We’ve often written about VDU regulations in relation to eye tests and eye wear, and we do communicate with Employers about this issue too. Unfortunately there does seem to a great deal of confusion in the UK about this whole subject.

A recent survey suggested that under half of the employees in this country are properly cared for by their employers in this area. It’s also reported that this is mostly due to the vague regulations and the fact that employers find it difficult to pin down exactly what their obligations are. Of those surveyed, only 69% of employers thought that the regulations were clear and that they were confident in their policies.

Further questioning showed that only 17% of those employers surveyed knew that they must pay for eye exams and VDU specs for employees who use VDUS. The problem lies in the fact that the regulations are not clear on the amount of time eligible employees are at their computers, and for which categories employers have to pay for glasses.

The rules state:  if the employee sends a significant part of the day at the screen, then the employers must pay for the test. If glasses are required specifically for the VDU, then the employed must pay for them. A prescription just for the VDU only arises in people over the age of approximately fifty, who have been using reading specs but then find they need a different power at middle distance, which covers the VDU screen.

If you’re not sure if you’re eligible, talk to your HR department, who can find the answers online – direct them to this article for a start! It makes complete sense for employers to avoid sick leave by looking after their staff and providing this inexpensive and basic service to improve the wellbeing of their team.

Keep it in the Family

Friday, May 14th, 2010

Within families it’s interesting to see what lovely traits get passed on from generation to generation. Knobbly knees? An obsession with train spotting? Freckles? We can look back at family photos and spot the likenesses, which can be a bonding moment and at the very least, quite interesting. But what if knowing about your family history could save your sight?

Like any other physical trait, eye conditions can be inherited. There are two important things to do here. Firstly, know your family history, and ask questions about any eye health issues. Patients come in and vaguely say that Great Grandma had funny specs, but it doesn’t help us in monitoring your eye health. Secondly, make sure you tell your optician what you find out! Pass on any information, and check if you need more regular eye tests. For instance, if you’re over forty and a close relative has Glaucoma, then you should have a test every year, which is free under the NHS.

Some eye problems are down to anatomy, so this could be an inherited trait just like eye or hair colour. Long or short sightedness, lazy eye, Glaucoma are just some of the problems that Mum or Dad may have kindly passed onto you! Age Related Macular Degeneration is more likely to occur if you have every light coloured eyes, so wear good quality sunglasses, have regular Retinal Imaging to check for early signs, and take an eye health supplement.

While your Optician is always on the look out for early signs of eye disease, knowing your family history gives you an extra advantage in knowing about early symptoms and preventative measures. Take your children for regular sight tests and pass on medical history. Don’t forget to tell your siblings if any problems arise – they’ll appreciate the advance warning too.

So even though you don’t want to keep health problems in the family, keeping the information there might just save someone’s sight.

Reducing the Risk

Monday, April 19th, 2010

Glaucoma is a common eye disease which can wreak havoc in a sufferer’s life. Production and drainage of fluid within the eye becomes unbalanced for various reasons, raising pressure within the eye and ultimately damaging the optic nerve. Although it’s easily detected and treated too many patients slip through the net, due to not having their eyes checked regularly. So the first piece of advice is to keep up with your eye tests, especially if you are over the age of forty, and if you have a family history of Glaucoma. But can you do anything else to reduce your risk?

Watch what you drink – We’re told to drink plenty of water for our general health, but there is some evidence to support the fact that excessive water consumption can raise the production of aqueous fluid in the eye. This will increase pressure within the eye, an early sign of Glaucoma. If you are susceptible to the disease, and your regulation of the fluid you produce is not good, then this may increase your risk. So drink plenty, but not vast amounts at any one time. Caffeine, particularly coffee can raise pressure, so drink in moderation, or switch to tea!

Stay Fit – Keeping active and regularly taking moderate exercise can reduce the internal pressure of the eye, just a modest 20 minutes of brisk walking about five times a week will help. Your good work will wear off about a month after you stop, so keep at it! Strenuous activities however, such as weight lifting, will temporarily affect pressure, so it’s best avoided if you are at risk.

Think about supplements – Selenium is a mineral which many people are aware of as a healthy supplement to eye health. Excessive amounts will actually cause Glaucoma, so eat a varied diet, including plenty of cereal, nuts, seafood and dairy products to get your Selenium, but avoid over consumption via supplements if you have other risk factors. Gingko Bilboa, used to enhance brain function and aid memory loss, also has many positive effects on the eye. So a supplement of Gingko can be beneficial

Smoking – of course this is an obvious one! It has such a disastrous affect on the body that of course it’s implicated as a risk factor with Glaucoma too – another incentive to quit!

Testing Times

Saturday, March 27th, 2010

It has been reported this week that paying for eye tests is becoming a thing of the past as so many opticians do the examination for free. This is a surprising development as the eye exam should involve many separate tests and thorough checking by a qualified professional. It should cover all the guidelines set out by the Government as well as individual investigation if problems are evident. How do you know if you’ve been checked properly?

The optician should take plenty of time to get to know you and your specific history and current symptoms, worries and problems. They need to know about optical problems in your family, medication you are using, and any odd optical effects or pain you are suffering. They also need to check the strength of your present glasses or contact lenses.

Pre-screening tests should cover your field of vision, the internal pressure of the eye, and Retinal Imaging or Ocular Coherance Tomography. All of these tests cover every aspect of your sight and eye health, so check that your optician can do them and has the training to interpret the results. Optical support staff may do the pre-screening tests for you, but your optician should be the one who looks at the results with you.

The optician will then check your sight, and the health of your eyes. They may need to refer you on for further treatment, or suggest a visit to your GP for problems such as high blood pressure. They will also discuss your needs with regard to spectacle or contact lenses.

Some opticians are also trained in specific areas such as sports vision, therapeutic contact lens wear, behavioural optometry and treatment for Dyslexic patients. As in every aspect of life you get what you pay for – so what are getting if the service is free?!! Scour the web and find an optician who will do the job properly, and don’t be afraid to phone ahead for advice.

All About Eye Tests

Friday, July 17th, 2009

If your eye sight is not up to the driving standard then you might be more dangerous than a drunk driver when out on the road. An eye test will detect eye diseases and pick up general health problems too. 89% of people fear the loss of their sight over any other sense, yet many do not have regular eye tests.

In the UK your eyes will be tested by an Optometrist – also called an ophthalmic optician. They are fully qualified, and are governed by the General Optical Council, who insist upon a specified list of tests, and control other issues such as the confidentiality of your appointment. The GOC suggest that eye exams are necessary every two years, although you may be recalled earlier if anything needs monitoring. The opticians will fully check the health of your eyes, and test your vision.

Eye Examination Routine

The optician will talk to you about any medication you are taking, your general health, and any symptoms you are concerned about. They will ask about your job, hobbies and sports activities, as these may affect the glasses they prescribe. They will assess the glasses you currently wear. You will then be tested in the following ways.

Intraocular Pressure

High pressure of the fluid inside the eye could mean Glaucoma, an eye disease that can lead to blindness. Nowadays most Opticians use a puff of air to read the pressure.

Visual Fields

A symptom of Glaucoma is a reduced field of view. The optician will check your peripheral vision, and your all-round vision.

Retinal Imaging

The optician uses a camera to take a picture of the retina, the light sensitive layer that lines the back of the eye. This can detect early signs of eye disease. During the rest of the test the optician sees small areas of the retina, with imagining they can see all of it and store the image for future reference.

Refraction

This tests your need for corrective lenses. You are checked for close work, intermediate – ie the VDU, and far distance. The optician uses a trial frame, into which he puts a series of test lenses, or a mechanised version called a phoropter. He may also use a hand held light to double check your prescription.

Pupil Reflex

This checks that your pupils react normally to light. Abnormal responses may be a sign of a neurological problem. The optician shines a light into your eyes to make sure your pupils dilate and contract as they should.

Oculomotor Balance

Muscles controlling eye movements have to co-ordinate, to give you comfortable vision and no double vision. There are several different ways of checking this.

Ophthalmoscopy – This is very important as it can detect eye health problems and general health issues such as high blood pressure, diabetes and macular degeneration. The optician uses a hand held instrument to examine the internal structures of the eye.

The optician will explain your results, and give you a copy of your spectacle prescription. In the event of finding any general or eye health problems that need treatment or investigation they will go through this with you and refer you to your GP.

Eye Health For Computer Users

Saturday, March 28th, 2009

In the years since we exchanged our slide rules for calculators, more and more of us use computers for longer periods each day. This raises questions about eye health and the VDU screen, so if you are worried about the hours you spend slaving over your keyboard, read on…..

Problems can arise because of the amount of time we spend in front of our computers. To counteract this you need to do a spot of eye exercise and remember to blink often, which moistens the surface of the eye, and try to get into the habit of looking away from the screen at regular intervals. This alters your focus and helps to prevent eye strain and fatigue.

You may need prescription glasses for the computer, and if so, an anti-reflection coating will help to reduce the effects of glare. You should also make sure that the glasses you are wearing are at the correct focal length. Tell your optician how far away the screen is when you work.

Have regular eye tests with a qualified optician and make sure your prescription glasses are up to date. If you spend most of your working day on a computer your employer will pay for the test, and the cost of the spectacle lenses. Buy glasses online and you can afford a few pairs, so you’re never straining to see the screen without them.
