Your eyes rely on the lens to focus light on the retina so that you can see sharply and clearly. Refractive disorders occur when the eye is not shaped or sized properly, preventing the lens from focusing light.
This video can help you understand the effects of the different refractive disorders, which include farsightedness, nearsightedness, and astigmatism. Farsightedness and nearsightedness are related to the length of the eye, as they occur because light is either falling on a point behind or in front of the retina, causing blurred vision in certain fields. Astigmatism is an abnormal curvature of the cornea that causes light to scatter as it enters the eye, so vision is consistently blurred.
