What is Hyperopia?
Hyperopia is what most people know as long-sightedness. People with long sightedness have to focus a certain amount in order to see the distance and near work clearly.
A small amount of hyperopia is not a problem because the eye can compensate easily. However, if there is a significant amount of hyperopia, the effort of focusing can lead to symptoms. Vision may become blurry, especially for close objects, because the closer the object, the more focusing is required.
Hyperopic people may get tired eyes or headaches after a lot of reading or computer work, even if their vision is clear.
What causes Hyperopia?
Hyperopia is often thought to be hereditary, but no-one is certain. The eyeball may be a little smaller than average.
Does Hyperopia change with age?
It tends to increase, but not always. We all find it harder to focus on close objects as we get older (due to Presbyopia). Hyperopes have trouble sooner and may need reading spectacles earlier because they have to focus more to start with when doing near work.
What do we do about Hyperopia?
The optometrist has many things to consider when making a decision and symptoms are very important. In general, young people who are slightly hyperopic do not have problems. If they do, they may need spectacles, mainly for close work such as reading and using computers. Older people, or young people with significant hyperopia, often have problems because focusing requires much effort. Their vision is more likely to be blurred, especially for close objects. They usually need spectacles for reading and sometimes for distance vision as well.
