Colour Vision Explained

Colour vision is a deficiency within the eye that causes the chemicals responsible for colour definition to be imbalanced. The result is that patients often describe difficulty distinguishing between certain colours, and grey colours. The extent to which a patient can distinguish colours can range from little or no difference to having a massive impact upon their life.
