TECHNOLOGY IN FOCUS


Advances in Eyewear Technology is touching nearly every aspect of our lives - how we see is no exception, with eyewear lenses becoming more comfortable, more attractive, and more effective in providing better vision. Thanks to technological advances and a growing demand from optometrists and patients alike, spectacles and contact lenses are now more sophisticated than ever before. By minimising lens thickness, thinner lenses made of a variety of high-index materials improve your appearance, reduce magnification of your eyes, and are lighter to wear than thicker lenses. When choosing these lenses, the type of frame and strength of the prescription needs to be considered. Applying an anti-reflective coating to lenses lets up to 10 percent more light through for better vision, while reducing glare, reflections and halos around lights. This is particularly useful for night driving, when reflections and oncoming headlights can be distracting. Polarised lenses perform a similar function, reducing reflections, filtering glare from wet roads or sun-baked sand, and improving visual clarity. Advanced coatings can even repel water and dirt, with obvious benefits to anyone who regularly works outdoors. Scratch resistant coatings offer considerable advantages for people whose jobs or hobbies involve dusty environments or regular lens abrasions. Photochromic or transition lenses have chemical coatings or special internal changes, allowing them to change from light to dark and back again, depending on their exposure to ultraviolet light. They darken quickly in bright conditions, offering 100% ultraviolet light protection. Patients requiring multifocal correction have seen some of the biggest improvements...

ARE WE MAKING A BIGGER SPECTACLE OF OURSELVES?


Is the number of people wearing glasses increasing? Or is this simply our perception? Does it seem that more people than before are wearing glasses? Or is this in fact true? According to statistics worldwide, this perception is reality; the incidence of people needing to wear glasses has increased significantly over the last few decades, and it is predicted that this trend will continue. Why is this so? Some experts have commented that we notice that more people are wearing glasses because we are living longer and populations of older people who need glasses have grown. Although this may be partly true, it does not account for the increasing numbers of younger people and children who are wearing glasses. Lifestyle has been cited as one of the reasons that more people are wearing glasses. As more and more people have moved from rural to urban environments, their visual needs have changed. Whereas for most jobs in rural areas people go about their daily tasks quite comfortably without realising they may need glasses, jobs in the cities usually require better clarity of vision.Some studies comparing visual requirements for rural and urban populations argue that people who don’t live and work in cities don’t develop myopia (shortsightedness), and that most people who wear glasses wouldn’t need them if they had grown up farming and never learnt to read. This is an over-simplification which doesn’t take into account that genetic factors have an important role to play in refractive errors such as myopia and...

FUN WITH EYE COLOURS!


The eyes are the windows to the soul and the eye colours are thought by some to have personality defining meaning as well. Brown eyes are all about the Earth qualities of a person, including energy, fertility, endurance, creativity, courage and grounding. Brown-eyed people love nature, are spiritual and are strong and independent. Black eyes imply mystery, witchcraft, secrets and darkness. The heroes in romantic always have “smouldering black eyes”! Hazel eyes speak of independence and courage. People with hazel eyes are thought to be sensible and empathic. Blue eyes remind us of the energy of the sky and water. Blue-eyed people are thought to be psychic, able to see into the future and the past! Green eyes are all about nature, healthy living and freshness. These people are compassionate and spiritual. Grey eyes - These people are wise, sensitive, and have an inner strength that not many others possess.

THE POWER OF COLOUR


Without us being consciously aware of it, colour exerts a huge influence on our lives. Colour is simply light of different wavelengths and frequencies, which is picked up by specific cells in the retina at the back of the eye. A message is sent to the brain which then interprets the colour. But it doesn’t end there! Colour is not simply a physiological reaction resulting from different wavelengths of light. The interpretation of colour is dependent on, and influences, personal preferences, emotions, mood, past experience, and even cultural and religious factors. It affects how we feel, how we dress, how we decorate our homes, and how we react to people and situations. Colour even has a role to play in how we express ourselves – “green with envy”, “having the blues”, “seeing red with rage”, and so on. Colour in Everyday life From using small electronic devices to navigating our way in vast spaces, colour plays a powerful role. Colour dictates our behaviour every single day – we stop at red traffic lights and go when the light turns green. We press the appropriate buttons on remote control devices, home appliances and credit card machines by responding to the colour of the buttons. We recognise items we use each day by colour and logos; think of the various cell phone companies, some of whom use colour as part of their advertising campaigns. The colour of an item informs our decision to buy it or not. Is the fruit ripe, still green,...

ALL IN THE FAMILY!


A new baby is born, and everyone who sees it has an opinion on who he looks like, where her red hair comes from, and whose character traits have been inherited. What about health problems, or more specifically, vision problems? Although there may be significant environmental factors present, genetic factors play a role in many eye conditions, as well as in general systemic conditions. Some of these are present at birth, while others may manifest only later in childhood or even adulthood. Congenital eye defects are present at birth, but may not necessarily be hereditary. Some are definitely known to be passed on through the genes, some are the result of factors which occurred during pregnancy or birth, while often the exact cause of the condition is unknown. ALBINISM Albinism is a hereditary condition in which there is a lack of normal pigment in part or all of the body. The hair is white, the skin very fair, and the iris of the eye is white or pinkish. The person with albinism usually has poor vision, an imperfectly developed retina, oversensitivity to light, and nystagmus (abnormal muscle movement causing constant twitching or jerking of the eyes). Specially treated lenses can improve vision and can also lessen discomfort by reducing the amount of light entering the eye. Ocular albinism is a genetic condition in which there is reduced pigmentation of the iris (the coloured part of the eye) and the retina (at the back of the eye), causing similar symptoms to those...

SITE FOR SORE EYES


The Sea Point promenade in Cape Town is well-known for its public art initiatives, which offer a platform for creative expression for artists and an opportunity for the public to enjoy and appreciate various works of art. A recent sculpture on display there is Michael Elion’s “Perceiving Freedom”. The giant stainless steel spectacles which “look out” towards Robben Island are a tribute to Nelson Mandela.

EAT YOUR CARROTS! NUTRITION FOR EYE HEALTH


While we are all aware and much is written about the importance of nutrition for general physical well-being, certain foods have a significant role to play in maintaining the health of the eyes. Vitamins A, C and E, zinc, lutein, zeaxanthin, and omega-3 fatty acids all play a crucial role in eye health. NUTRIENTS FOR EYE HEALTH Carrots and other brightly coloured fruits and vegetables are loaded with beta-carotene , which converts to vitamin A and forms a purple pigment in the retina of the eye called rhodopsin. This is needed by the eye in order to see in dim light, and insufficient amounts of rhodopsin can contribute to night blindness. Foods rich in antioxidants can help protect against free radicals which cause damage to the retina and the lens. They also minimise damage to the eyes from cigarette smoke, pollution and sunlight. Certain foods contain an antioxidant called glutathione , which attacks free radicals and aids in cataract prevention. Recently it has been suggested that two antioxidants, lutein and zeaxanthin may lower the risk of developing macular degeneration. Other antioxidants that protect against free radicals are vitamin C and vitamin E , which also work together to keep the tissues of the body strong and healthy. Healthy fats that contain omega-3 fatty acids keep the blood vessels and nerves that go to the eyes healthy, and help fight inflammation. WHAT TO EAT It is always best to get the nutrients our eyes and bodies need from the food we eat....

MOM, CAN I GET CONTACT LENSES, PLEASE?


The answer to this plea is not a simple one, with good reasons to say ‘yes’ as well as ‘no’. Although Harry Potter has made the wearing of glasses seem ‘cool’ and even fashionable, some children feel self-conscious about looking different and are afraid of being teased at school. The boost to a child’s confidence, self-esteem and even academic performance with the wearing of contact lenses is a very good reason to say ‘yes’, but there are many more fundamental issues that need to be taken into account. Contact lenses can provide better vision than glasses, especially in children who are very short-sighted. For sports activities, they provide better peripheral vision, improving awareness and sports performance. They are safer than glasses during sport – if glasses break during sport, they can result in an eye injury. For children with very different vision in each eye, contact lenses can ensure that messages being sent to the brain from the eyes are from both eyes, not only the stronger eye, thus reducing the possibility of ‘lazy eye’ (amblyopia) developing. Several studies on myopia (short-sightedness) in children have shown positive indications that wearing contact lenses may slow the progression of myopia. These results are inconclusive and research is continuing, but many optometrists in practice have reported good results in this area. Children who are not good candidates for contact lenses are those who suffer from seasonal allergies. The wearing of lenses may increase the discomfort of itchy, burning and watery eyes caused by the...
