Health eye tip

Good sight occurs when the eyes and the brain work in harmony transforming the light rays into sight. Light rays pass through the transparent cornea, the clear front part of the eye. The cornea focuses light rays through the pupil and the lens, which focuses the light further. The lens is made of a clear, flexible gel surrounded by the transparent lens capsule. The light rays focus onto the retina, the thin sheath of nerve cells at the back wall of the eye. Once the retina has received the light images, it transforms into them electrical impulses, The optic nerve carries these impulses to the visual cortex of the brain, where they are interpreted into sight.
When any part of the visual system is not working properly, the sight processes are altered. If the cornea curvature is too much the light ray will focus in front of the retina causing the image to be blurry. This is called myopia or nearsightedness. The opposite is true, if the cornea curvature is less than normal the light rays will focus further back from the retina. It is called hyperopia or farsightedness. The lens helps to focus the light rays onto the retina further when the object is at close range. When a person reaches over 40 years old, the lens loses its flexibility and the person can not see at close range without wearing reading glasses.

The complexity of the developing visual system in infants and children makes their eyes uniquely different from adults’ eyes. Any hindrance to eye stimulation can quickly cause a condition called "lazy eye" or Amblyopia , which can result in permanent deterioration of a child’s vision.
