Good vision is something we often take for granted - until we need new glasses. But regular eye tests are about far more than just updating your prescription. They are a health check for your eyes and can detect serious conditions like glaucoma, cataracts, and diabetic retinopathy before you notice any symptoms.

The question is: how often should you get tested? Where do you go? And how much will it cost?

Here is everything you need to know about eye tests in the UK in 2026.

Do You Qualify for a Free NHS Eye Test?

Many people pay for eye tests when they are actually entitled to a free test on the NHS. The eligibility criteria are broader than most people realise. Over 30 million people in the UK qualify for free NHS eye tests.

If You Don't Qualify for Free Tests: How Much Do They Cost?

If you fall outside the free NHS eligibility criteria, you can still get an eye test, but you will need to pay privately.

Private eye test costs: Between £24 and £35 at most opticians (as of July 2026). This varies depending on the optician and location, but this range gives you a good benchmark.

Keep in mind: the cost only covers the eye test itself, not the glasses or contact lenses. If you need new prescription eyewear, that is an additional cost.

How Often Should You Have an Eye Test?

The frequency of eye tests depends on your age, health, and whether you have been identified as at risk of eye problems.

General Recommendation: Every 2 Years

If you qualify for a free NHS eye test and are in good eye health with no known risk factors, the NHS recommends you have an eye test every 2 years. This is sufficient to catch most vision changes and eye health problems.

More Frequent Tests Are Recommended For:

• Children: Annual tests are recommended from school age (or earlier if there is a family history of vision problems like squints or short-sightedness)
• Older adults (60+): Annual tests are recommended due to increased risk of age-related eye conditions
• Diabetes: Annual tests are recommended to monitor for diabetic retinopathy
• Glaucoma or at risk of glaucoma: Annual tests or more frequently depending on your risk level
• If advised by your optician: If your eye test identifies early signs of a condition or other clinical concerns, your optician may recommend testing more frequently than every 2 years

Where to Get Your Eyes Tested

High Street Opticians

Most UK high streets have one or more optician shops. The major chains include Specsavers, Boots Opticians, Vision Express, and Asda Opticians. Independent opticians are also available in most towns. All of these offer NHS eye tests if you are eligible.

You do not need to buy glasses from the same optician where you get your test. You can take your prescription to any eyewear shop.

Find an NHS-Contracted Optician Near You

The NHS has a postcode checker that helps you find NHS-contracted opticians in your area. Visit www.nhs.uk and search for "find an NHS optician" to locate your nearest options. You can also call your GP surgery for recommendations.

Mobile Eye Testing

If you are unable to leave your home due to disability or mobility issues, you may be able to get a free mobile eye test where the optician comes to your home. This service is available in some areas - ask your GP or local optician if this is available to you. This is particularly valuable for older people and disabled people who find travelling to an optician difficult.

How to Book Your Eye Test

What Happens During an Eye Test

An NHS eye test usually takes 20-30 minutes and includes:

• Vision check: Reading letters on a chart to test your distance and close vision
• Eye pressure measurement: To screen for glaucoma
• Retinal examination: The optician looks at the back of your eye to check for signs of disease
• Colour vision test: If relevant to your age or health
• Visual field test: Checking your peripheral (side) vision, especially important for glaucoma screening
• Refraction test: Determining the correct lens prescription for your glasses or contact lenses

The optician will discuss your results with you, let you know if your prescription has changed, and discuss any eye health concerns they may have identified.

Optical Vouchers: Help With the Cost of Glasses

If you qualify for a free NHS eye test and need glasses, you may also be eligible for an NHS optical voucher to help towards the cost of your frames and lenses.

Optical voucher values depend on your prescription strength (from £42.40 for basic prescriptions to £233.56 for complex prescriptions as of 2026). You can use the voucher at any optician shop - high street chains or independents.

This voucher does not mean your glasses are free, but it significantly reduces the cost. Many opticians have glasses that cost less than the voucher value, meaning your glasses are entirely free.

After Your Eye Test: Protecting Your Vision Investment

Once you have had your eye test and purchased new glasses, protecting them is essential. Quality glasses are an investment in your vision and your independence.

A good glasses case is not just an accessory - it is protection. Our vegan leather glasses cases are designed to protect your frames and lenses from:

• Scratches to the lenses
• Bent or damaged frames
• Dust and dirt
• Impact damage if dropped
• UV damage if left in the sun

Replacing damaged glasses is expensive. A quality glasses case costs a fraction of the price of replacement lenses or frames.

Final Tips for Eye Health

• Keep to your appointment schedule: If you qualify for a free eye test, use it. Regular testing catches problems early.
• Tell your optician about your health: Mention diabetes, high blood pressure, migraines, or medication you take - all can affect your eyes.
• Ask questions: If you do not understand your results, ask your optician to explain. Your vision is your health.
• Protect your glasses: Use a case when you are not wearing them. This is the easiest way to keep them in good condition.
• Take breaks from screens: If you spend a lot of time looking at phones, computers or tablets, take regular breaks. Follow the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds.
