Definition


Myopia is a condition of the eye, or more specifically a condition affecting the eye's refractive ability, meaning the point of convergence of light as it passes through the different elements of the eye. People with myopia have poor vision over long distances, with distant objects appearing out of focus. This happens due to the rays of light that come from the far-off object converging before they reach the retina. For closer objects, their vision remains clear. The problem originates either from the eye being "too long", or from an excessive curvature of the cornea. Myopia can be treated surgically, yet it is more common for the eye's focus to be corrected with glasses or corrective lenses.
