Long-sightedness, or far-sightedness, is a sight problem that affects your ability to see close-up objects. People who are long-sighted can usually see distant objects clearly, but nearby objects appear blurred.
The medical name for long-sightedness is hyperopia.
Who is affected
Long-sightedness can occur at any age, but it becomes more noticeable after the age of 40, when the lens of the eye becomes stiffer and starts to lose its focusing power (see Long-sightedness - Causes for more information). This age-related long-sightedness, known as presbyopia, can get worse with age.
Some children are born with long-sightedness, although this normally corrects itself as they grow older and their eyes develop. However, it is important that children have regular eye tests as long-sightedness that does not correct itself can lead to other eye problems such as crossed eyes (strabismus) or lazy eye (amblyopia).
Some cases of hyperopia may run in families.
Outlook
Long-sightedness can be easily corrected with glasses, contact lenses or corrective surgery (see Long-sightedness - Treatment for more information). Laser surgery is an increasingly popular option, but is not suitable for everyone.
