What you should know about Eye Care when you turn 40

Consider your world should you lose your eye sight or even have your vision compromised? Too ghastly to contemplate! Trauma can of course result in the sudden loss of vision, although it is generally not a common cause of blindness. Several of the ocular diseases that can cause vision loss can be successfully treated, provided they are diagnosed at an early stage. It is important to note that the incidence of ocular disorders increase as we get older, but also that some of the serious ones are asymptomatic – you won’t know it’s there.
What is Keratoconus and what can be done?

Keratoconus is a progressive eye disease in which the normally round cornea thins and begins to bulge into a cone-like shape. This cone shape causes distorted vision. As the disease progresses, vision will progressively deteriorate. Keratoconus usually begins during late teens or early 20s and can occur in one or both eyes. Keratoconus signs and […]
Ageing – what it does to your eyes

For the past thirty years the improvements in hygiene conditions and medical progress have led to an impressive reduction in morbidity amongst elderly people, many of whom now live without any major incapacity to over 80 years and beyond. Why do we age? The important question that we all ask ourselves still remains. As we age, our past abilities are substituted by new and increasing inabilities that mark every stage on our final journey. Our various organs age in their own specific ways: blood vessels lose their suppleness, the heart is invaded by fibrosis, the brain by neurofibrillar degeneration and the appearance of a senile plate, the kidney function declines, immune defences are down and the frequency of cancer increases with age.
Advantages of prescription sunglasses

Your spectacles may give you excellent vision indoors and at night. But they can’t provide optimum vision outdoors on a sunny day. For that, you need prescription sunglasses. If you require vision correction, there’s no substitute for prescription sunglasses outdoors. Only prescription sunglasses can give you the best possible vision correction and a wide variety of tints to provide you with the most comfortable vision possible in bright conditions. Most high-fashion sunglass frames can take prescription lenses.
Office Eye Problems

Two main eye-related problems occur regularly in an office setting. They are dry eye and neck and shoulder pain related to posture. Apart from making you miserable, they can seriously transform productivity. It’s hard to do your best when suffering discomfort. A differentiating factor that comes into play is age. Different age groups require different types of visual corrections, which will impact on how the work station should be set up. You should also not underestimate the atmosphere in the office because heating and air-conditioning systems put a strain on your eyes. So make sure you have a pleasant indoor climate by ventilating sufficiently in summer and increasing the humidity in the room in winter with the aid of water bowls placed on the radiators.
What is strabismus and what can be done?

Strabismus, commonly known as squint is a group of conditions in which one or both eyes are not aligned or pointed in the same direction. The condition is important since if one eye is not aimed at the same target as the other eye, then two images (double vision) will result. Although strabismus usually shows up in infancy or early childhood, adults can develop strabismus as well.
Child Vision

Many young kids have started their school careers this year. For the first time, demands will be placed on their visual systems like never before. Since it is unknown territory to them, it is unrealistic to expect them to report on any shortcomings as far as visual function is concerned. It is the parents’ responsibility to ensure their child has a comprehensive visual examination before being sent off to school.
Colour Blindness

A general consensus is, if you suffer from colour blindness you cannot see any colours at all apart from black, white, and shades of gray. Wrong! This form of complete colour blindness is a very rare subtype of colour vision deficiency. A much more common type is red-green colour blindness. Generally speaking, colour deficiency would be more appropriate than colour blindness. Colour Blindness begins when you have only a very light change of colour perception and it ends with complete colour blindness combined under the umbrella term monochromacy.
What’s the difference between vision screening and comprehensive eye exam?

Vision screenings are general eye tests that are meant to help identify people who are at risk for vision problems. Screenings include brief vision tests performed by a school nurse, paediatrician or volunteers. The eye test you take when you get your driver’s license renewed is another example of a vision screening.
Refraction and Refractive Errors

We have to go fetch the story in 1672 when that clever guy, Sir Isaac Newton, first published his experiments on the refraction of light. He was the one that discovered it, and just like two plus two will always be four, his principle is still as steadfast as ever. What we know is, that […]
