A cataract is a clouding of the lens in your eye that, sadly, is an inevitable consequence of getting older. Cataracts usually occur when normal proteins in the lens of the eye break down and clump together, clouding the lens. Because the lens is no longer as clear as it should be, rather than following a usual path, incoming light is scattered. The cataract or cloudy lens blocks the passage of light to the retina in the back of the eye, causing distorted or blurred vision, issues with glare and difficulty handling bright light . Basically, a cataract is a

iD Lifestyle 3 Progressive Lenses – very clever
Looking forward through glasses New Zealand has a population of around 4.8 million people, and in 2020 the median age was 38. This basically means that half the people in New Zealand are younger than 38 and half are older.

Myopia in children
What is myopia? Myopia is blurry long-distance vision, often called short-sightedness or near-sightedness. A person with myopia can see clearly up close – when reading a book or looking at a phone – but words and objects look fuzzy on a blackboard, on television or when driving. Experts across the globe have concluded, with good evidence, that myopia leads to further sight-threatening conditions. Myopia is spreading Research published in the British Journal of Ophthalmology showed 10 million people worldwide suffered from myopia in 2010. By 2050, it is estimated that more than 50% of the world’s population will have myopia,

Sun protection & polarised sunglasses
I think it’s fair to say that most us know that long-term overexposure to ultraviolet radiation (UVR) from the sun can lead to eye damage and that sunglasses are an effective method of UV protection, but what do we know about sunglasses? Sunglasses vs. sunglasses In New Zealand particularly, we know how important sunscreen and hats are for UV protection, but good sunglasses are just as critical. Wearing a broad-brimmed hat and sunglasses that meet the Australian and New Zealand Sunglass Standards can reduce UV radiation exposure to the eyes by up to 98 percent. However, not all sunglasses are

Itchy eyes – again?
Hay fever horrors Rising sea levels, horrendous storms: climate change is hammering the world – yeah right. You can believe it or not, but one thing that about 20% of the New Zealand population can attest to is that the increase in temperatures means longer growing seasons, and higher pollen counts for allergy-causing plants, such as trees, grass, outdoor moulds and weeds. Hay fever brings with it red, watery, itchy eyes. Pollen power Climate change could contribute to longer – and harsher – hay fever seasons. Pollen season, which typically runs from late winter until the end of summer, is

Keratoconus: causes and treatment options
Keratoconus – Progressive thinning and distortion of the cornea Keratoconus is an eye disease of the cornea: the thin, clear tissue covering the surface of the front of the eye. A normal, healthy cornea is round in shape, but sometimes the cornea can weaken, losing its shape. Instead of a dome, it becomes cone-shaped, preventing clear vision. This is known as keratoconus. It is a progressive disorder that can either progress rapidly or take years to develop. It may affect only one eye but more commonly occurs in both. Causes of Keratoconus The cause of keratoconus is unknown. It is
