Eight ways you're damaging your eyesight (and how to fix it)
Most of us don't think twice about our vision - until it starts to change.
For a lot of people, that moment comes sometime in their forties. You hold your phone a little further away. The menu at dinner is suddenly harder to read. Your eyes feel tired after scrolling. It sneaks up on you.
What's actually happening is called presbyopia - the lens inside your eye gradually becomes less flexible, making it harder to focus on close-up things. It's completely natural, as normal as a few grey hairs or a new wrinkle, and it happens to almost everyone eventually.
The good news? It's a simple fix with a great pair of reading glasses.
Cataracts and macular degeneration might feel like distant, old-age concerns - but the damage that leads to them starts much earlier than most people realise. Decades earlier, in fact.
Oxidative stress and UV damage build up quietly over a lifetime. By the time symptoms appear, the process has often been underway for years. That's why regular eye tests matter so much - even when your vision feels perfectly fine. Catching changes early means treatment can start before any vision is lost.
The three simplest things you can do to protect your eyes for the long term? Wear sunglasses every time you're in the sun, don't smoke, and eat plenty of green leafy vegetables like spinach, kale and cabbage.
Small habits. Big difference. Starting now.
How to protect your vision
Stop smoking If there's one change that makes the biggest difference, this is it. Smokers are up to four times more likely to develop age-related macular degeneration, and tend to develop cataracts significantly earlier than non-smokers. The encouraging news? Quitting at any age - even after decades of smoking - starts to reduce that risk.
Eat for your eyes Carrots get all the credit, but dark leafy greens like spinach and kale are actually superior for eye health. They're rich in lutein and zeaxanthin, which build up in the macula to form a natural protective layer - essentially acting like built-in sunglasses that filter harmful blue light. Add brightly coloured fruits and vegetables like berries and peppers for vitamin C, which keeps the blood vessels in your eyes healthy.
Drink in moderation The occasional glass of wine is unlikely to cause harm, but heavy drinking depletes your body's stores of vitamin A and blocks the absorption of key eye nutrients. In serious cases, alcohol can damage the optic nerve - causing permanent vision loss.
Follow the 20-20-20 rule Screen time reduces your blink rate by around 60 per cent, leaving eyes dry, gritty and strained. The fix is simple - every 20 minutes, look at something 20 feet away for 20 seconds. It relaxes the focusing muscles in your eyes and encourages a full blink, refreshing your tear film. Small habit, big relief.
Wear polarised sunglasses year-round UV damage accumulates over a lifetime, contributing to both cataracts and macular degeneration - much like the way sun ages your skin. Cloudy days count too.
Stop doomscrolling in the dark Holding your screen too close strains your eyes, causes headaches and can worsen short-sightedness - particularly in younger people. Try setting up a screen distance alert on your phone, and always match your screen brightness to the light in the room. Scrolling in a pitch-dark room is one of the worst things you can do for your eyes.
Get regular eye tests Many serious eye conditions show no symptoms in their early stages - which is exactly when they're most treatable. An eye test every two years is recommended for most adults, and annually once you're over 60. Don't wait until something feels wrong.
Take care of dry eyes Avoid overusing contact lenses, and consider warm compresses to help with hydration. Lubricating drops during the day and a thicker ointment at night can make a real difference for anyone who regularly struggles with dryness or discomfort.
