If you don’t currently wear glasses or contact lenses, you might find that when you think of an eye test the picture conjured up in your mind is the card and chart of your school days. While eye tests when you were a child were great for identifying those who might need help in correcting problems with their vision, eye tests have come a long way since.
These days eyes tests combine traditional testing methods with new techniques and technologies to get an in-depth picture of the health of your eye. For those that do wear contacts or glasses, regular eye tests are essential for making sure that their prescription is up to date and best for their eyes. For those that don’t at the moment, tests can identify if there are any signs of weakness in the eyes.
While many people wouldn’t consider having an eye test unless they are having problems with their vision or are experiencing commonly known side effects such as headaches, eye tests are for much more than checking whether you are long or short sighted. Advances in technology mean that these tests can now help spot the warning signs for other aspects of eye health.
For example, an eye test will allow opticians to pick up on the early signs of eye diseases such as glaucoma and cataracts and can also be vital in the early detection of health problems such as diabetes or high blood pressure. This means that eye examinations are far more in-depth than ever before.
When you go for an eye test, you’ll find that your optometrist will be interested in much more than how clearly you can read the infamous letter chart. They will also compile a detailed history and details of your lifestyle, they will also use autorefraction to determine your baseline prescription and they will use tonometry to measure the pressure in your eyes – this is vital as it’s a key factor in identifying glaucoma.
Your optometrist will also conduct a slit lamp exam, allowing them to look at your cornea, conjunctiva, lids, iris and lens under high magnification with the help of a microscope and a small beam of light. They will also be examining the strength and flexibility of your eye muscles and carrying out a full retinal exam, to ensure that they have a broad and comprehensive picture of the health of your eyes.
A modern eye test may sound complicated, but your optometrist will talk you through the process and ensure that you get the best out of your exam.

Let’s start by explaining what we mean by “prescription” as there are two meanings in this context and there is often confusion.
Just as glasses can be prescription or non-prescription, so too can contact lenses. Prescription lenses or glasses are intended to correct a vision disorder whereas non-prescription contact lenses or glasses are effectively clear. That is, they do not alter your vision. Colored contact lenses are a typical example of non-prescription contact lenses although it is now possible to get non prescriptioon contacts in a range of colors.
The other thing we mean by the word “prescription” is the piece of paper you get after a sight test which explains the type of contact lens you need to correct your vision. It will detail the curvature of the lens and the strength of the lens.
People who want to buy contact lenses without prescription usually mean that they haven’t had a recent eye test but they want to buy lenses based on their last known prescription. This is also true of people wanting to buy non prescription colored lenses without a prescription.
If you think that your eyesight hasn’t changed you probably think it quite reasonable to buy lenses without an up to date prescription. The same applies if you want to buy colored lenses. The fact is, however, in many countries it is simply impossible to buy contactlenses without prescription, whether they are prescription lenses or not and whether they are colored or not.
You may think that this is unfair, after all, it’s your eyes which might be at risk. But remember this. You only have one pair of eyes and you want to be certain not only of the quality of the lenses you are putting into your eyes but that they are suitable for your eyes. Not every make of lens suits every person, and not every lens will fit your eye. A regular eyesight test will also pick up on any other problems which might have developed in your eyes since your last test.
It makes a lot of sense to get a current prescription, even if you do happen to live somewhere where you can buy contact lenses without prescription.

It is recommended in the UK that people with eye or vision problems should have an eye test every two years. There are a variety of reasons behind this, and it is very important that you do get regular eye tests because they could save you a lot of trouble in later years.
Primarily, eye tests serve as a check up to ensure that your vision correction prescription – ie, your glasses and/or contact lenses – is up to date. Without the right prescription, not only can your sight suffer but the condition of your eyes can decline overall. This means that bigger problems could occur in the future that can be rectified in advance simply by having an eye test.
Eye tests also serve as a way for optometrists to monitor any early signs of eye disease. As with many health problems, the sooner a problem is identified, the sooner it can be treated – with a higher likelihood for success than if the problem is allowed to persist. Problems like glaucoma and cataracts can be identified far earlier than they might be if left alone, and dealt with in a comparatively painfree fashion.
At an eye test, your optometrist will undertake several measures to determine the health of your eyes and the quality of your vision. These include a discussion of your health and lifestyle background, followed by tests such as the measurement of your spectacle power, the measurement of your eye pressure – key to discovering glaucoma – autorefraction to help with your base prescription and a test of your visual acuity. This test determines how well your vision works based on near and far distances, usually involving the reading of letters on an eye chart.
There are other tests your optometrist in order to determine any other problems you may have, which check the general health of your eyes, including the strength and flexibility of the muscles in the area.
By booking regular eye tests, it is far more likely that you will save yourself from future pain and discomfort due to the greater chance of identifying any problems before they become too difficult, as well as ensuring your prescription is completely up to date so you are not at risk of entailing any other damage.
Your optometrist will also be better informed to suggest a course of treatment, whether it is new glasses or LASIK laser eye surgery for corrective purposes – making regular eye tests an essential part of your routine health checks.
