CARE OF THE BODY’S INDIVIDUAL PARTS: EYES

The eye is like a camera. The front part consists of the cornea— the transparent area in the centre—surrounded by the sclera, as the white of the eye is called. Behind the cornea is the coloured part, or iris, in the middle of which is the pupil, which grows larger or smaller to control the amount of light let into the ‘camera.’ The clear, transparent lens, located slightly behind the front surface, focuses the image on the retina, which is about three quarters of an inch behind it. The optic nerve carries the picture from the retina to the brain. The eye also contains muscles to do this work and fluid to keep the parts in working condition.

If I asked you whether you would mind being blind, you would call it a ridiculous question. Most people consider blindness the worst thing that could happen to them. But you would never guess it from the way they treat their eyes!

Probably some of you who are reading this have to squint to do so, or hold the book close to your nose, or wish your arms were longer so you could hold it farther away. You know you should have your eyes examined—but you put it off because it can wait, or because you do not want to be told you have to wear glasses. Even some serious eye conditions have been neglected, with tragic consequences, for these foolish reasons.
