Hyperopia (also called hypermetropia or long-sightedness) is a condition in which the eyeball is too short, or the cornea is too curved, or a combination of both. The result is that light from objects is focused behind the retina. We can use some of the focusing power of the natural lenswithin the eye to help refocus the light, but this can lead to "eyestrain" or tired eyes, especially when working at near. The focusing ability of the eyes also reduces as we get older, making it more difficultto overcome thefocusing problem. Hyperopia can be corrected with either soft contact lenses or RGP (gas permeable) contact lenses.
