Reminders for a regular eye test: why the two-year rule is easy to miss

Eye tests aren't just about updating a glasses prescription. They're one of the few routine health checks that can detect serious conditions — glaucoma, macular degeneration, diabetic retinopathy, even signs of high blood pressure — before symptoms appear. Most opticians recommend a test every two years for adults with no known conditions, more frequently for people with diabetes, a family history of eye disease, or existing vision correction. The problem is that two years feels like a short time when you're in the optician's chair, and an impossibly long time when you're trying to remember how long ago that was. A recurring reminder solves this with no mental overhead.

What an eye test can detect beyond poor vision

A routine eye test is a window into your general health that many people underestimate. An optometrist can detect signs of glaucoma through intraocular pressure checks and optic nerve examination, often years before any vision loss occurs. Diabetic retinopathy — a leading cause of blindness — shows up in the blood vessels of the retina before symptoms develop, making eye tests an important part of diabetes management.

High blood pressure, multiple sclerosis, and even certain brain tumours have been detected during what patients thought was a routine vision check. None of this means an eye test replaces other health monitoring, but it does mean skipping it has more potential consequences than missing a glasses update.

Why the two-year interval is hard to self-track

The optician gives you an appointment card. You put it somewhere safe. You either lose it or find it again in 18 months. This is the universal experience. Unlike annual dental check-ups, which many people treat as a fixed yearly commitment, eye tests don't have a strong cultural anchor to a particular season or time of year.

For people with glasses or contact lenses, the need for an eye test becomes more obvious when vision changes noticeably — but that's not how eye health works. Many serious conditions develop silently, and the two-year guideline exists precisely because you won't feel the need for a test before symptoms appear.

Setting up a recurring eye test reminder

Create a one-time reminder for approximately 22 months after your last eye test with the message 'Time to book your next eye test — it's been almost two years.' The 22-month timing gives you lead time to get an appointment, since optician slots can be several weeks out.

After your test, reschedule the reminder for 22 months from that date. If you wear contact lenses or glasses, note in the reminder message whether your prescription was due for review — useful context when calling to book. For children, annual tests are recommended throughout school years, so adjust the interval accordingly.

Eye test reminders for the whole family

If you manage health reminders for an elderly parent or a child, eye tests are one of the checks most likely to slip. Use ReminderIt's recipient feature to set a reminder that calls their phone — or yours, with their name in the message — at the right interval. A simple message like 'Book Dad's eye test this month — two years since his last one' means no one has to hold the tracking in their head.

For children, note that free eye tests are available to under-16s and full-time students under 19 in the UK. Include this in the reminder message: 'Book [child's name] free NHS eye test — dentist can recommend an optician.'
