Far sightedness is also called as hyperopia. In this the person is able to see near objects clearly but has a difficulty to see near objects clearly. It is a defect of vision caused due to imperfection in the eye. Farsightedness occurs when the eyeball becomes too short or the cornea has too little curvature, such that the light entering the eye cannot be focused correctly. It is a refractive error in which the eyes are not able to bend or refract the light completely to a single focus to view a clear image. In this case the image is formed behind the retina. It may be due to two reasons: low converging power of the eye lens because of weakening of ciliary muscles and eyeball becoming too short due to which the distance between the eyeball and retina decreases and the image is formed behind the retina.
