Why Everyone Over 40 Should Have a Regular Eye Check-Up

“But I can see perfectly well” is the reason most people give for skipping an eye check. It’s also exactly why regular examinations matter so much after 40 — because the conditions that threaten sight in adulthood often begin with perfect vision and no symptoms at all.

What can hide behind good vision

Several important conditions develop silently:

• Glaucoma damages the optic nerve painlessly, taking side vision first — you may not notice until a lot is lost. More on glaucoma here.
• Diabetic retinopathy can be advancing at the back of the eye while your vision feels normal.
• Early macular changes can begin subtly before central vision is affected.
• Cataract develops gradually — and a check helps you plan, not panic.

A routine examination is designed to catch all of these at the silent, treatable stage.

The eye as a window to your health

An eye examination doesn’t only check your eyes. Because we can directly view blood vessels and nerves at the back of the eye, a check-up sometimes gives the first clue to diabetes or high blood pressure — occasionally before those are diagnosed elsewhere.

How often?

As a general guide for adults with no specific problems:

• 40–60: every 1–2 years
• Over 60: every year
• Sooner and more often if you have diabetes, a family history of glaucoma, high spectacle numbers, or any new symptoms

Your eye doctor will tailor this to you. You can read about our comprehensive eye examination here.

Good vision is not the same as healthy eyes. A regular check is how you make sure the two stay together.

If it’s been more than a couple of years — or if you’ve never had a proper adult eye check — this is a good time to book one.
