Before you come in, here are a few things to remember
Preparing for your appointment has never been easier. Use our Store Visit Checklist (below) to ensure you have everything you need for a smooth and efficient experience. From bringing your current glasses to checking your eligibility for NHS‑funded eye tests, this quick guide has you covered.
What happens in an eye test?
There are three main parts involved in our typical eye tests:
History and symptoms
This gives you the opportunity to discuss any concerns you have about your eyes, vision or current glasses, and whether you’re experiencing any symptoms which might need further investigation.
Your optometrist will ask about your general health, medications, any past treatment on your eyes, or if there are any family members with eye conditions. All this information helps them to tailor the examination to best suit your needs.
The tests
We use a variety of tests and equipment to assess different aspects of your eye health and vision. Some are common to all eye tests – for example, the letter chart indicates how clearly you can see – while others may be used when further investigations are required, for example, to check if your eyes can see colour normally.
Some of the common tests, like the visual field test and the eye pressure test (puff of air test), can be performed by an optical assistant on behalf of the optometrist before the eye examination. These are known as diagnostic tests and help to make the process more efficient.
Summary and advice
Once all the relevant tests have been carried out, your optometrist will be able to discuss the results and offer any advice. This could be a simple ‘all clear’ on the eye health front, or they might talk you through particular lens options to match your prescription and lifestyle.
At this point, treatments for any eye conditions are also discussed, as is possible referral to a specialist if required.
What happens in the pre‑test?
Tonometer
A tonometer will blow a gentle puff of air onto the surface of each eye to measure the internal pressure.
This is one of a variety of tests that allows the optometrist to assess your risk of developing glaucoma.
Autorefractor test
This machine measures the ability of your eyes to focus and can be used to assess how long‑ or short‑sighted you are.

Digital retinal photography
The optical assistant may then take a photograph of the back of your eyes using a fundus camera. This image is saved and is useful in monitoring changes in eye health on future visits.
Optometrist check
The optometrist will check the health of your eyes and look for signs of other medical conditions. They will ask you if you are experiencing any eye problems and about your general eye health and lifestyle. It is important to have a clear understanding of your needs so that we can select the best management plan and/or corrective lenses for you.
Stages of your optometrist check
The vision test is used to fine‑tune their findings, the optometrist will ask you to read from a Snellen test chart, that's the one with the letters that get smaller. This test measures your visual acuity, i.e. how well you can see with and without lenses in front of your eyes. This use of lenses is known as refraction and lets the optometrist know which strength prescription gives you the best vision possible.
Ask your local store for an OCT scan so you can add it to your normal eye test. OCT (Optical Coherence Tomography) is a hospital‑grade eye scan that helps us to view the structures of your eye in even greater detail.
Using light waves to create a 3D image of your eye, it can help our optometrists spot signs of eye health issues up to four years earlier than traditional methods.
Many of these conditions, such as glaucoma and diabetic retinopathy, form at the very back of the eye so it's really helpful to be able to take a much closer look using the scan results.
Your optometrist will ask you to look into a machine while the scan takes place ‑ it takes just a few seconds to complete. Not only does OCT allow your optometrist to keep track of your eye health, but previous scans can be used to monitor subtle changes over time. This is a great scan to have if you have a condition like diabetes or are over 25 years old.
An Ophthalmoscope is a specialist torch used to examine the retina at the back of the eye, your optic nerve and its blood vessels to make sure they are healthy.
A slit lamp is a powerful microscope that is used to examine the front surface of the eyes. Your optometrist will use this to check for abnormalities or scratches on your cornea, iris and lens. It is a particularly important check for contact lens wearers.
A Visual field check test will assess your ability to detect flashes of light in your peripheral vision. Visual field tests are often used to detect early stages of glaucoma or any conditions that could be associated with headaches and other health issues.
Your eye test results
At the end of your eye exam, your optometrist will give you a copy of the prescription and can answer any further questions you may have. They will then recommend the best options for you – this might be glasses, contact lenses or maybe a referral to explore any eye conditions that have shown up in your eye test requiring specialist care.
