Your vision changes as you get older — that much is normal. But how do you know when what you’re experiencing is just ordinary ageing, and when it might be something more, like the early stages of cataracts? Here’s how to tell the difference.
What “Normal” Age-Related Vision Change Looks Like
Most people notice some vision changes from their 40s onward. Typically, this shows up as:
- Difficulty focusing on close-up objects, like reading a menu in dim light
- Needing more light to read comfortably than you used to
- Mild difficulty adjusting between near and far focus
This is usually presbyopia — a gradual, expected change in how your eye’s lens flexes. It’s not a disease, and it’s easily managed with reading glasses, multifocal lenses, or procedures like Presbyond.
What Cataracts Actually Are
A cataract is different — it’s the clouding of the eye’s natural lens, which sits behind the iris and pupil. Instead of a gradual softening of near focus, cataracts affect the clarity of vision overall, at any distance.
Signs That Point More Toward Cataracts
- Cloudy or blurry vision that doesn’t correct with a new glasses prescription — if you’ve recently updated your glasses and things still look hazy, that’s worth mentioning to your optometrist.
- Colours looking faded or yellowed — many people don’t notice this until it’s pointed out, because the change happens gradually.
- Increased sensitivity to glare, especially oncoming headlights at night.
- Halos around lights, particularly noticeable when driving after dark.
- Frequent prescription changes in a short space of time, rather than the slow, predictable shift typical of ageing.
- Double vision in one eye, which is far less common with ordinary age-related changes.
Why the Distinction Matters
Presbyopia is something you adapt to and manage. Cataracts, left untreated, will typically continue to worsen over time and can eventually significantly impact daily activities like driving, reading, and recognising faces. The encouraging part: cataract surgery is one of the most common, safest, and most effective procedures in modern ophthalmology, with most patients seeing a dramatic improvement in clarity within days.
When to Get Checked
If you’re noticing glare, halos, or a general “cloudiness” that a new glasses prescription doesn’t fix, it’s worth having your eyes properly assessed rather than assuming it’s “just age.” An eye specialist can distinguish between the two quickly using a slit-lamp examination — a simple, painless part of a standard eye check.
Not sure which one you’re dealing with? A comprehensive eye assessment can give you a clear answer — and, if it is cataracts, a clear path forward.
