The D15 is a colour vision arrangement test that is done to see if a person has moderate or severe colour vision deficiency. It’s usually a requirement for jobs that demand high-level colour recognition for safety and accuracy, especially if they have failed the Ishihara plate test. Some of these jobs may include: police officers/constables, […]
Scleral lenses are large, gas-permeable contact lenses that rest on the white part of your eye (the sclera) rather than directly on the cornea. They create a smooth, tear-filled surface over the eye, providing clear and stable vision for people who can’t wear traditional contacts comfortably. They are great for patients with the following conditions: […]
Photochromic coatings are slowly gaining popularity again. It is a special lens treatment that automatically adjusts the lens of your glasses based on surrounding light conditions. For example when exposed to UV rays, like sunlight, the lenses darken to act as sunglasses. Indoors or in low-light environments, they return to a clear state. This technology […]
Have you ever wondered how your eyes adjust when the lights go out? Our ability to see at night comes from the amazing teamwork of special cells in the retina called rods and cones. Cones help us see color and fine details in bright light, but they don’t work well in the dark. Rods, on […]
When it comes to kids’ eyesight, two common conditions often pop up: myopia and hyperopia. Both affect how your child sees the world, but in very different ways. Myopia: Seeing Near, Struggling Far Also called nearsightedness, myopia is when your child can see things up close clearly—like books, phones, or tablets but distant objects appear […]
Lutein is a powerful antioxidant found in leafy greens like spinach and kale. It plays a key role in keeping your eyes healthy by protecting them from blue light and oxidative damage. This nutrient concentrates in the macula—the part of your retina responsible for sharp central vision—helping to reduce the risk of age-related macular degeneration […]
Keratoconus is an eye condition that causes the normally round cornea to thin and bulge into a cone-like shape. This irregular shape prevents light from focusing properly on the retina, leading to blurred or distorted vision. The exact cause is believed to be linked to genetics, eye rubbing, and certain medical conditions. It often begins […]
You’ve probably heard people say they have “20/20 vision” or you may have been telling your friends and family that, but what does that actually mean? 20/20 vision refers to visual acuity, or how clearly you can see details at a distance. If you have 20/20 vision, it means you can see at 20 feet […]
Back-to-school season isn’t just about new backpacks and pencils, it’s also the perfect time to think about your child’s vision. Clear eyesight is essential for learning, but did you know many kids struggle in school simply because they can’t see properly? Keep an eye out for these clues that your child may have vision issues: […]
Did you know your eyes have their own “internal pressure”? It’s called IOP (intraocular pressure), and it’s key to keeping your eyes healthy and your vision sharp! It is maintained by the fluid (aqueous humour) that nourishes and hydrates it. Like a balloon, your eye needs just the right pressure to hold its shape. Too […]
