Eye Examinations

There is much more to an eye examination than meets the eye. Regular eye examinations are a vital health check and not just an assessment of whether you need spectacles or not.

No matter what age you are, you need to have regular examinations. Conditions that you are not necessarily aware of, such as diabetes, glaucoma and high blood pressure, are often first detected by an optometrist, who can refer patients on for further medical attention. It is recommended you have an eye examination at least every two years or more frequently if advised by your optometrist.

During your eye examination we will:

Eye Examinations and Eye Tests

Check the reason for your visit

Your visit may be routine, or you may have noticed that your eyesight is perhaps not as good as it should be. Your optometrist will discuss any special demands made on your eyes by work, sports or hobbies. We will also enquire about your general health, medication and whether anyone in your family has an eye condition.

Check your eyesight

To check your eyesight you will be asked to read the letters on a chart. There is a range of other tests (including picture tests) for those who cannot read.

Check your outer eye and inner eye

The health of your eye will be checked using a variety of specialised instruments. Microscopes will be used to closely examine the tissues that make up the eye and photographs of the inside of the eyes can be taken to assess the health of your retinae. The eye is the only place in the body where the blood vessels are directly visible and, as they are some of the finest in the body, they can often be the first ones to start showing signs of vascular disease. The eye’s proximity to the brain also means that some neurological conditions can be diagnosed from an eye examination.

Check your eye muscles

The correct neurological control of these muscles is crucial to the normal development of vision in children. Your optometrist will check that the muscles which control your eye movements are working well together to give you stereoscopic vision.

Check to see if you need your vision correcting

If you need spectacles to improve your vision, the optometrist will work out exactly what prescription you need. We may shine a light in your eyes and then ask you to look at colours, circles and letters on a chart through various lenses in a special frame.

We are authorised to carry out DVLA assessments, and we are one of the few practices in the country registered to examine and supply spectacles for flying to RAF pilots.

Instruments

Corneal topographercornealtopographer.jpg

The corneal topographer is used to create a contour map of the cornea. This is useful for diagnosing and monitoring conditions such as keratoconous, as well as for contact lens fitting. By measuring up to 90% of the corneal surface and analyzing over 80,000 points, a contact lenses can be tailor made to the shape of the eye to maximize vision and comfort.

Fundus Camerafunduscamera.jpg

The fundus camera digitally photographs the retina at the back of the eye. This is the part of the eye that acts like a camera film and it can be affected by many problems associated with eye disease or general health conditions. Every retina is unique, like a fingerprint and so building up a history of retinal photographs allows us to look for changes over time and greatly increases the chances of recognizing a problem before it starts to cause difficulties.

Slit Lampslitlamp.jpg

The slit lamp, or bio-microscope is usually used to assess the health of the front of the eyes. It is in effect a big microscope with a bright light which can be angled to illuminate different areas of the eye.

Tonometer

Tonometers are used to check the pressure of the fluid inside the eyeball.

Visual Field Analyser

The Visual Field Analyser is used to examine the sensitivity of peripheral vision.visualfieldanalyser.jpg This is usually done with one eye at a time, but can be done with both when assessing vision for driving, etc.
