The human eye is a marvel of evolution, operating very much like a regular camera. Light is focused by the cornea and lens, at the front of the eye and the image falls on the retina at the back of the eye, which acts like a film in the camera.
Deviations are referred to as ‘refractive errors’, and the vast majority of these can be corrected with spectacles, contact lenses or surgery.
Please click on the refractive errors below to learn more about these conditions and possible treatments.
Myopia – the technical term for short sightedness. Being able to see objects at close range, but distant and even mid range objects would be blurred.
Hyperopia – the technical term for long sightedness. Being able to see distances clearly, but close up images will be blurred.
