When was your last eye test? If you’re squinting to remember, it might be time to book an appointment. Eye tests are often overlooked until there’s a noticeable problem—but regular check-ups can do much more than just check if you need glasses. An eye test is a vital part of maintaining your overall health, and here’s why it should be on your to-do list

It’s Not Just About Your Eyes

Many people think of an eye test as simply a way to get a new prescription for glasses or contact lenses. But optometrists do much more than assess your vision. During a routine eye exam, they can detect signs of serious health conditions, including:

Diabetes – Diabetic retinopathy can be spotted during an eye test, often before other symptoms appear.
High blood pressure – Changes in the blood vessels at the back of the eye can indicate hypertension.
Glaucoma – Often symptomless in the early stages, glaucoma can cause irreversible damage if left undetected.
Macular degeneration – Early diagnosis can help manage the condition and slow its progression.

In many cases, your eyes can reveal the first signs of systemic conditions. That’s why the NHS and major UK health organisations recommend regular eye exams even if you think your vision is fine.

Essential for Children’s Development

For children, good vision is critical for learning and development. Undiagnosed eye problems can affect school performance, reading ability, and confidence. The NHS advises that children have their first eye test at around the age of four or five, or sooner if there are concerns. Regular checks help ensure that any issues—such as lazy eye (amblyopia), squint, or colour blindness—are identified and treated early.

Your Prescription Can Change Without You Noticing

Your eyesight can change gradually over time, making it easy to adjust without realising you’re not seeing as well as you could. Struggling to read signs or text, frequent headaches, or eye strain while using screens may be signs your prescription needs updating.

Even if your vision seems fine, the recommended frequency for eye tests is:

Every 2 years for adults aged 16 to 69.
Annually for those over 70 or people with certain medical conditions.
Annually or more frequently for children if advised by an optometrist.

Eye Tests Can Be Free on the NHS

Many people in the UK are entitled to a free NHS eye test, including:

Children under 16 (or under 19 in full-time education)
People aged 60 and over
Those receiving certain benefits (like Income Support or Universal Credit)
People with diabetes or glaucoma
Those over 40 with a close relative who has glaucoma

You can check your eligibility on the NHS website.

Peace of Mind and Prevention

Vision changes can be subtle, and some eye conditions progress silently. Regular eye tests provide peace of mind that everything is as it should be—or that any problems are being caught early enough to manage effectively. Prevention is always better than cure, and when comes to your eyesight, this couldn’t be more true.

Don’t Wait—Book Your Eye Test Today

Think of your eye test as a routine health check—like going to the dentist or GP. It’s a quick, painless appointment that can make a big difference to your quality of life.
