Eye Injury: What to do

You’ve probably heard that blue light from screens can damage your eyes, but is that actually true? Here’s what research shows: blue light from screens does not damage your eyes the way UV light does. However, spending hours on screens can still lead to digital eye strain, and evening screen time may interfere with your natural sleep-wake cycle.  Symptoms of Digital Eye Strain: - Tired, sore or gritty eyes - Blurred vision after screen time - Headaches or difficulty focusing - Dry eyes from reduced blinking - Trouble sleeping after late-night device use

Blurry vision can happen all of a sudden or develop gradually over time. Understanding when it starts can help us figure out what’s going on. Sudden blurry vision may signal something more urgent, such as: Retinal detachment or tear Acute glaucoma attack Vascular events (like a blockage in eye blood vessels) Gradual blurry vision is often caused by: Refractive errors (myopia, hyperopia, astigmatism) Cataract development Dry eye disease Macular changes (like age-related macular degeneration)

If you’re applying for or renewing your aviation medical, you may need to complete a CASA eye exam with an optometrist. At VISION Michael Hare Optometrists, we regularly perform these assessments and know exactly what CASA requires. What is the CASA eye exam? This occupational assessment ensures your vision meets the safety standards for aviation. It covers a wide range of visual functions, not just how well you can read an eye chart.

Noticing your vision getting cloudy or dimmer, especially when driving at night or dealing with glare? You might be developing cataracts, a condition where the eye’s natural lens becomes cloudy over time. Cataracts usually develop gradually as part of the ageing process. Other factors that can increase your risk include long-term UV exposure, smoking, diabetes, and certain medications. What Are the Symptoms? Cloudy, fuzzy, or film-like vision Increased sensitivity to bright light or glare Difficulty with night driving Colours looking faded or yellowed

Colour vision is how your eyes tell the difference between colours. Most people can see colour normally, but about 1 in 12 men and 1 in 200 women are born with a colour vision deficiency, commonly known as colour blindness. What Is Colour Blindness? Colour blindness is usually inherited. It happens when the colour-sensing cells in your eyes (cones) don’t respond properly to red, green, or blue light. The most common type is red-green deficiency, which makes it harder to tell those colours apart. Less common types affect blue-yellow vision, and a very rare form impacts all colours. Signs of Colour Vision Deficiency People with colour vision issues may: - Struggle to tell red from green - Have trouble reading colour-coded maps, charts or wiring diagrams - Find colour-based tasks challenging at school

If you have diabetes, type 1 or type 2, it’s important to keep an eye on your eyes. High blood sugar can damage the delicate blood vessels at the back of the eye, leading to diabetic retinopathy, macular swelling, or even permanent vision loss. The tricky part? It often starts with no symptoms at all. Why Regular Diabetic Eye Checks Matter: Diabetic eye disease can be silent at first. Early detection gives the best chance to protect your vision. Medicare covers diabetic eye exams for eligible patients. We coordinate with your GP or specialist for complete care. Even if your blood sugars are well managed, regular eye exams are essential.
