Vision Correction
This refers to a number of techniques used to improve visual clarity and correct common refractive errors like myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.
Refractive errors are caused by the shape of the eye failing to focus light accurately on the retina, resulting in blurred vision.
People with myopia have trouble seeing objects from a far distance, whereas farsighted people struggle with near vision. Astigmatism results in distorted images due to the cornea or lens being irregularly curved.
Fortunately, refractive errors can be easily corrected using corrective lenses like glasses and contact lenses.
