Your Eyes in Focus
  • The processes needed to perceive images account for about 40% of the body's calorific consumption when it is just resting. So closing the eyes is a great way to rest.
  • Our eyes send signals to the brain, via the optic nerve. It is only when these signals have been processed by the brain that we are then able to 'see'.
  • In bright light our eyes are able to process colours and fine details. In dim light, the eyes have to adapt using different receptors (rods) but the images are grey and sometimes fuzzy.
  • If the eyes and the brain are not working correctly vision is impaired and a visual correction may be required to assist in 'seeing'.

If your focus is imperfect (i.e. when the cornea, lens or eye is an irregular shape), light cannot focus accurately on the retina and the image you see is blurred.

Laser eye corrective surgery is ideally suited to the treatment of such conditions.
