Introduction:
Refraction is the ratio of the refractive power of the lens and cornea (the refractive media) to the axial length of the eyeball. It is characterized by changes in direction of light as it passes from one transparent medium into another with different optical densities. If there is a discrepancy between the eyeball’s axial length and the cornea’s and lens’s ability to focus light, then the condition is known as ametropia (refractive error). , It occurs when the parallel light rays incoming through the eye (with…
