Farsightedness is of course corrected with a convex lens. The principle of farsightedness is that distant objects are imaged on the retina through the refractive system of the eye, and in order to see distant objects clearly, the eye’s accommodation power must be used to gradually move the image to the retina. Depending on the degree of farsightedness, there is a range of accommodation used. In mild hyperopia, objects can be seen using the regulation of the human eye. For moderate to severe hyperopia, such as 400-600 degrees or more, the regulation of the human eye may not be possible and must be corrected with the help of a convex lens, which converges the light on the retina so that objects can be seen clearly.
