Anatomy of the Eye

THE ANATOMY OF THE EYE

Introduction

The eyes are undoubtedly the most sensitive and delicate organs we possess, and perhaps the most amazing. They present us with the window through which we view the world, and are responsible for four fifths of all the information our brain receives – which is probably why we rely on our eyesight more than any other senses.

Common Eye Problems:

Myopia (short sight) and Hypermetropia (long sight) are common conditions and are both caused by the cornea and lens not focusing properly on the retina.

Short sight is where the eyeball is elongated or the lens is too thick, causing the image to focus in front of the retina.

There are other sight-threatening conditions that are not so easily corrected or overcome. Cataract, trachoma, glaucoma and river blindness , for example, will cause complete blindness if left untreated. Sightsaver is preventing and curing these diseases and restoring sight where possible.

Causes of Blindness

When you think about it, the very act of actually seeing the world around us is an astonishing thing. It relies on the interaction between the brain and the eyeball, two extraordinarily complex organs, so it’s hardly surprising that there are so many ways in which we can suffer sight loss or reduction.

    Thanks for sharing. I agree that our eyes are the most amazing of all the senses. Thus, we should take the very best care of it. If we feel any abnormalities in our eye site or any different feelings in our eyes our doctors will have the best answer for us. This site could also be helpful.
