The human eye is sense organ which reacts to light and give us sight. The human eye can distinguish about 10 million colours. The weight of an eye is around 7.5 grams and attains full size by the age of 13 years.
Our eyeball consists of three layers namely the outer layer which is called the cornea and sclera, the middle layer consists of choroids, ciliary body and iris and finally the inner layer is called the retina.
Common Defects:
The most common defects of eyesight are Myopia (Short sightedness), Hypermetropia (Long sightedness) and Presbyopia (due to aging). In myopia, the image is formed short of the retina, and in hypermetropia and Presbyopia, the image is formed beyond the retina.
