Some people have defective colour vision. This may be inherited or acquired later in life as a result of a disease of the eye. This is more commonly found in males.  Very few of these people are totally colour blind, most have a reduced ability to recognise or discriminate colours and see colours differently from those who have normal colour vision.

Corneal topography is a computer assisted diagnostic tool that creates a three-dimensional map of the surface curvature of the cornea. The cornea is responsible for about 70% of the eye's focusing power. If the cornea is too flat, steep or unevenly curved less than perfect vision results. The greatest advantage of corneal topography is its ability to detect irregular conditions invisible to most conventional testing.


Retinal Imaging is a digital picture of the back of your eye. It shows the retina, the optic disk and blood vessels. This helps your optometrist find certain diseases and check the health of your eyes.Retinal imaging allows optometrists to get a much wider digital view of the retina.

Optical coherence tomography (OCT) is a non-invasive imaging test. OCT uses light waves to take cross-section pictures of your retina. With OCT your optometrist can see each of the retina's distinctive layers. This allows us to map and measure the thickness. These measurements help with diagnosis. They also provide treatment guidance for glaucoma and diseases of the retina.


A visual  field test is an eye examination that can detect dysfunction in central and peripheral vision which may be caused by various medical conditions such glaucoma, tumours or other neurological deficits.Visual field testing can be performed clinically by keeping the subject's gaze fixed while presenting objects at various places within their visual field.

Early detection, through regular and complete eye exams, is the key to protecting your vision from damage caused by glaucoma. A complete eye exam includes five common tests to detect glaucoma. Examining the inner eye pressure, the shape and color of the optic nerve, a complete field of vision test,  the angle in the eye where the iris meets the cornea and the thickness of the cornea.

Diagnosing glaucoma is not always easy and careful evaluation of the optic nerve continues to be essential to diagnosis and treatment.


Diabetes is a disease that profoundly affects many areas of your body, including your eyes. It increases your risk for eye conditions, such as glaucoma and cataracts.

They are able to provide a certificate stating that your eyesight is satisfactory for driving.

Low vision is often a loss of sharpness or acuity. It may also present as a loss of field of vision, light sensitivity or a loss of contrast. A person is said to have low vision when their eyesight is limited or impaired and cannot be adequately corrected with surgery, conventional glasses or contact lenses.


Sport is an important part of many people's lives, from the weekend warrior to the elite athlete. Vision plays a huge role in ball sports but also in movement through space.
