Common Eye Conditions
Our visual system is one of the most complex in our body. Most of the information we require for everyday living is obtained through our eyes. As with most complex systems, there are many things that can go wrong. Fortunately, most problems can be prevented or corrected, provided they are detected early enough.
How does the eye work?
The eye can be regarded as working in much the same way as a camera. The cornea, pupil lens and vitreous gel are clear and allow light to focus on a thin sheet of tissue in the back called the retina. The retina itself has photoreceptor cells to transform light energy into nerve impulses as well as nerve fibers to transmit those impulses back to the optic nerve.
