Hyperopia (Farsighted) – Unable to see well at distance or near. Usually farsighted people “grow” into their prescription. They can accommodate (make their eyes work hard) to see at distance. Many people have “hidden” farsightedness. They don’t realize that the eye strain and fatigue when reading is because of uncorrected prescription. If you wear contacts the sign in front of the prescription number is a plus (+).
(example: +4.50 soft contact lens power)

Farsightedness (Hyperopia) occurs when the eyeball is too short front to back, or the eye's focusing mechanism is too weak, causing light rays to focus behind, rather than on the retina. People with hyperopia have difficulty seeing near objects clearly, such as words in a book. In order to correct this vision problem, opticians prescribe convex or 'plus' lenses. These lenses have thick centers and thin edges.
