30 Minutes to Save Your Sight

Posted On 12 May 2014


There are so many enjoyable things to be done with half an hour – watching your favourite TV programme, going for a run or even baking a cake – all things we’re sure you’d rather do than attend a sight test.
However, eye tests are about more than determining whether you need new glasses or not – your eyes are like windows into your general well-being and can reveal common health problems like high blood pressure, cholesterol and diabetes- which is why a sight test should be a part of everyone’s regular health regime.

Did You Know, In The UK:

100% should attend a full sight test every 2 years – yet some people may need them more frequently?
8% of UK adults have not had a sight test for at least 10 years
3% of UK adults have never been for a sight test


With all the high-tech equipment and tests, it’s normal to be nervous if you don’t fully understand what your sight test involves, but there’s nothing to worry about – just read our step-by-step breakdown.


It’s important to understand your lifestyle and personal requirements before your sight test, which is why our optometrist will have a chat with you when you arrive. They will ask:
• What has prompted your eye test?
• About your lifestyle – what do you do at work and in your spare time?
• About your current glasses or contact lenses (if you have them)

They will then explain what will happen in your sight test and may conduct tests using the following:

The Lensmeter – To ascertain the prescription of your current glasses

The Auto-Refractor – To examine the curvature of your eye. This will help our optometrist to identify what type of correction you may need

Pressure Test – To measure the internal pressure of the eye as this is one of the indicators of conditions like Glaucoma

The Field Test – Checks your field of vision how much of the world you can see


The Eye Chart
A familiar sight at the opticians, you will be asked to read letters from a chart to ascertain your standard of vision without any lenses in front of your eyes, so the optometrist can find out how well you see without glasses or contact lenses.

The Trial Frame
You will be asked to wear a trial frame into which the optometrist will present different lenses, to see how they improve your vision.
Looking at the eye chart, the optometrist will ask you if your sight improves each time. When the best level of vision is achieved you will be asked to view the letter chart again, so you can experience the difference with the prescription, before it is confirmed.


After the vision test, your optometrist will undertake a series of tests to check the health of your eye:

The Light Test
A light from a torch-like instrument will be shined into your eye to allow the optometrist to see the light sensitive layer at the back of your eyes (the retina). This also allows the optometrist to check the health of the blood vessels too.

The Retinal Camera
Some opticians have a retinal camera which photographs the retina, which enables both you and the optometrist to view the back surface of your eye. The photograph will remain on your records so it can be compared to new photographs each time you visit – making it easier to detect changes.


After all the tests have been conducted, the optometrist will upload all of your results on to the computer so that each time you visit they can review your notes and compare findings. They will then discuss their findings and makes sure you are happy with what they have discussed. They will also provide:
• Advice on aftercare
• Product recommendations
• Your prescription
• Details of when you will need your next need a sight test
But don’t worry- we will send you a reminder before your next sight test is due so you never miss it.
