Ocular conditions that affect the population are as follows:
Ametropia: Refers to the need to use corrective lenses to focus images that enter the eye.If the light rays do not focus properly refractive errors such as astigmatism, myopia or hyperopia are presented.
Myopia
Difficulty seeing far away. Eye length is long, the light rays focus before retina.
Difficulty seeing far away. Eye length is long, the light rays focus before retina.
Hyperopia
The length of the eye is too short and light rays focus beyond the retina, causing nearby objects appear blurred.
The length of the eye is too short and light rays focus beyond the retina, causing nearby objects appear blurred.
Astigmatism
In astigmatism, unequal curvature of the cornea causes light rays impinge at different points outside the retina and objects both near and far are not distinguished clearly.
