Summer is here and whether you’re fishing, boating, at the beach or just out for a walk, it might be time to start thinking about polarised sunglasses. Why? So you can enjoy the word around you without the bright white stain of glare. Tinted lenses vs. polarised lenses While tinted sunglasses are great for reducing brightness and UV rays, they don’t necessarily eliminate harsh glare like polarised sunglasses can. Polarised lenses will not only reduce glare caused by water, snow, flat roads and windscreens, they enhance visual clarity and contrast and reduce eye strain. What are polarised lenses? They are

Blue Control Glasses
Why do I need blue control glasses? Using your computer or smartphone for hours each day can have long-term effects on your vision. We use these devices at work, on the road and at home, often holding them at a short distance, so our eyes have to constantly refocus. Digital devices, LCD and LED screens, fluorescent and LED light globes emit blue light and protecting your eyes from this high-energy visible (HEV) light can significantly mitigate the risks of retinal degenerative diseases. Why is blue light harmful? It’s natural light, isn’t it? Blue light is a naturally occurring light. Its short, high-energy blue

Myopia – what you can do
Myopia is the medical term for nearsightedness. Myopia is where the eyeball is too long or too powerful. The result is blurred vision; far away objects become blurry, but vision for close objects is clear within a certain range. 60 years ago, 10-20% of the Chinese population was short-sighted. Today, up to 90% of teenagers and young adults are. In Seoul, 96.5% of 19-year-old men are short-sighted. In USA and Europe, approx. half of young adults are myopic, double the prevalence of half a century ago. Worldwide, it is estimated that 2.5 billion people (roughly 1/3 of the world population)

What is Myopia?
Myopia, or shortsightedness is a refractive disorder. Myopia occurs when the eye physically grows too long. When a light wave enters the eye, it is bent by the cornea as it makes its way through to land on the retina – the light-sensitive tissue in the back of the eye. If the eye is too long, the lens of the eye focuses the image in front of the retina instead of on top of it. People with myopia have good near vision but poor distance vision. Causes of myopia Myopia is most often inherited. However, the recent dramatic increase in the prevalence

Eye Colour
Where’d the green-eyed monster come from? If both parents have blue eyes, the children will have blue eyes. True or False? False. It’s rare, but blue-eyed parents having brown-eyed children does happen. Why? Well, it’s complicated, but we can start by telling you that what you learnt at school, assuming you are of a certain age, is wrong. The human eye comes in many different shades and intricate, unique iris patterns. Eye colour comes from a combination of two black and yellow pigments, melanin, in the iris. If you have no melanin in the front part of your iris, you have

What Is Macular Degeneration?
Facts About AMD AMD causes damage to the macula and can gradually destroy your central, sharp vision. AMD, or age related macular degeneration, is a common eye condition and a leading cause of vision loss among people age 55 and older. It is the most common cause of legal blindness in this age group. (Legal blindness means that a person can see 6/60 or less with glasses.) The macula is made up of millions of light-sensing cells. It is the most sensitive part of the retina and is smaller than the size of a pinhead. The macula allows us to make

Treating Dry Eyes
Are your eyes dry, red, irritated or watering? You may be one of the many New Zealanders who suffer from dry eye syndrome. Dry eye is a debilitating, common condition, particularly in older adults. The two most common causes of dry eye are oil glands getting clogged and inflamed or glands not producing enough lubricating tears. Tear production tends to diminish with age or as a side effect of certain medications. Environmental conditions, such as wind, air-conditioning, smoke, dust, dry heat and low humidity, can also affect tear volume. Intense concentration associated with close or computer work, which affects blink

Blue Control Lenses
Looking To The Future Stepping into sunlight, flicking on a light, turning on your computer, phone or other digital device, all these things cause your eyes to be exposed to visible, and invisible, light rays. Sunlight contains red, orange, yellow, green and blue light rays. Light moves as waves of different lengths: some are short with more energy, making bluer light, and some are long, with less energy, making redder light. As sunlight reaches our atmosphere, molecules in the air scatter the bluer light but let the red light pass through. We see the sky as blue because the shorter, smaller waves

Makeup and Eye Health
Healthy Eyes Are Beautiful Eyes Beauty is timeless, but unfortunately, beauty products are not. For many women, putting on makeup can be a part of their daily routine, but when makeup is not used properly, cosmetics can cause infections, allergic reactions and even injuries. Our eye specialists also see patients coming into our optometrists with eyeliner and mascara residue stuck to contact lenses or trapped in tear films and tear ducts. Some of the most common causes of eye infection come from dirty sponges and old cosmetics: mascara, eyeliner and eye shadow. In fact, according to a Reuters news article

Looking and Learning
Young Eyes and Learning We live in a visual world and there is a very clear connection between good eyesight and learning success at school. Experts say that about 80 percent of what children learn at school is presented visually: good vision is essential for students of any age if they are to reach their potential. Research has shown that in New Zealand around 15% of children have problems with their vision; many of the children are pre-schoolers. If left untreated, eyesight problems can impact on learning, confidence and sports. If your child is not doing so well at school, ruling
