Hyperopia is a common vision problem which affects about one in four of the general population. It is often called Long Sightedness. In hyperopia, the eye focuses the image too far behind the retina. This may often result in near blur. Or in moderate or high hyperopia, blur at all distances. With effort it is sometimes possible to force the eye to bring the image into focus with effort. Although in many young people this may cause an eye turn.
- Eye Strain
- Fatigue especially doing sustained near work
- Inwards eye turn (especially in young children)
People often confuse hyperopia with presbyopia, which also causes near vision trouble but for reasons related to the normal aging process.
Long sightedness can be corrected with glasses or contact lenses. If your glasses or contact lens prescription begins with plus numbers, like +2.50, you are long sighted. Long sighted glasses tend to magnify images and are thicker in the centre of the lens. It is common that hyperopic prescriptions also include some correction for astigmatism also.
Some people get away without full time correction. But this depends on how long sighted you are, how young you are and how flexible your visual system is. You may need to wear your glasses or contacts all the time. Otherwise only when reading, working on a computer or doing other close-up work.
