How Eye Health Changes Throughout the Years

As your body develops through the years, your eyes change and may be affected by different conditions…


Kids and teens

Developmental issues

“If a child’s poor eyesight isn’t corrected by the age of eight, it can never be corrected fully, even with glasses,” explains Omar Hassan, head of professional services at Vision Express. “School performance can drastically improve with the right glasses too.”

20s and 30s

Sun damage

The sun can cause a lot of eye degeneration. “People use sunscreen, but don’t take the same careeyes on the sun with their eyes,” says Omar. The cornea can suffer from sunburn, which leads to problems later on, so wear sunglasses.


In recent years there’s been a huge increase in the number of people diagnosed with myopia or short-sightedness – 27% of adults are now short-sighted, compared to just 10% in the 1960s.
“Myopia is simple to correct with glasses or contacts, so there’s no need to lose out on your senses,” says Omar.

Screen time

“The screens themselves aren’t affecting people’s vision – if you stared at a painting for a long time it would have the same affect,” says Omar. “But the more you use your eyes, the more tired they’ll get.” So take regular screen breaks.

40s and 50s


If you find yourself holding the paper far away from you, you may be suffering from presbyopia, or long-sightedness. It becomes more common after 40, even for those who have never had problems with their vision before.
“It’s critical to have glasses made for you, rather than relying on ready-readers, which won’t correct 100% of the problem,” says Omar. “Off-the-shelf glasses are just magnifiers of different strengths, whereas proper glasses will correct any stigmatism in the eye, meaning you’ll see a sharper image, not just a bigger one.”

Dry eyes

“Watery eyes happen when sensitive spots in the eye get dry, so it over-produces tears,” explains Omar. “Take breaks from screens, and blink regularly to replenish the moisture in your eye, or you could try eye drops.”



Post 40, everyone will have some form of cataract (a clouding of the lens). Most cases need monitoring rather than treatment.
“In advanced cases, cataract extraction surgery may be needed,” says Omar. “It’s one of the most routine operations in modern medicine, with very high success rates.”

Age-related macular degeneration (AMD)

This is the most common form of sight loss in over 60s in the UK, with 200 new cases diagnosed every day. The condition causes gradual central sight loss (what you see when you focus straight ahead). With an ageing population, it’s estimated this figure will double by 2050.
“Unfortunately, there isn’t a cure for AMD, although there are injections that can halt its progress,” explains Omar. “But it can lead to significant blindness if left untreated.”
