HOW TO PROTECT AND CURE EYE DEFECT
Eyes are most important sense organs which allow us to view this colorful world. We use our eyes to distinguish different colors and lights, change these visions and images into neural signals and finally transmit them to the brain. A saying that “eyes are the soul windows” obviously reveals the importance of eyes. However, people will not notice the importance of eyes until when they lose the vision. Eyes are quite vulnerable like too many disorders like dryness, itching, pink eye, cataract, glaucoma, myopia, hypermetropia.
The structure of the eye
The white part of the eye is the sclera maintaining the shape of the globe, offering resistance to internal and external forces. It ensures the outside of the eye is light-tight so that light can only enter through a small opening, the pupils. This produces clearer vision because a smaller opening creates a sharper image.
Myopia & Hyperopia
(Nearsightedness and farsightedness)
Myopia (Nearsightedness) which often happens to young people is a medical condition that collimated light produces images focuses in front of the retina and those with myopia see near objects clearly but far away objects appear blurred.
Causes of Myopia
Excessive near sight work like prolonged reading and sitting in front of a computer screen
Heredity also cause myopia
Hyperopia means that the image is focused behind the retina and it often occurs to the elder. Common signs of farsightedness include difficulty in concentrating and maintaining a clear focus on near objects rather far objects, eye strain, fatigue and/or a headache after close work
Causes of Hyperopia
Hyperopia is typically caused by gene and is often confused with presbyopia, a condition that good far vision is observed but blurred near vision occurs because of a reduced accommodative amplitude brought about by natural aging changes with the crystalline lens.
