Behavioural Optometry:

The function of our eyes is to collect information. In order to do this efficiently we need to be able to see well in the distance and at near. We must be able to change focus efficiently from distance and near and back again.

We also must have good eye movements so we can get our eyes pointed at what we are obtaining information from and then be able to track this object. One in three children has problems in one or more of these areas that could impact on their learning.

Are a cloudy areas that form in the lens of the eye. The lens is normally clear. Poor vision results because the cloudiness interferes with light entering the eye. The opacities in the lens scatter the light, causing hazy vision.

Is a condition in which the nerve cells which transmit information from the eye to the brain become damaged. This prevents visual information from getting from the retina in the eye to the brain.

The eye’s lens and cornea focus light into an image on the retina, just as a camera lens focuses light on to a film. In a hyperopic (longsighted) eye, the light is focused behind the retina and so the image is blurred.

Macula Degeneration (ARMD):

Is damage or breakdown of the macula. The macula is a very small part of the retina, the light-sensitive tissue of the eye.

Patients with diabetes are more likely to develop eye problems such as cataracts and glaucoma, but the disease’s affect on the retina is the main threat to vision.

Virtreous Detachment:

This a common degenerative change which occurs in one or both eyes of most people after middle age. It is not usually caused by trauma of any kind.
