Hyperopia, or farsightedness, is a common vision problem, affecting about 25% of the population. People with hyperopia can see distant objects very well, but have difficulty seeing objects that are up close.
Hyperopia Symptoms and Signs
Farsighted people sometimes have headaches or eyestrain, and may squint or feel fatigued when performing work at close range. If you get these symptoms while wearing your spectacles or contact lenses, you may need an eye exam and a new prescription.
What Causes Hyperopia?
This vision problem occurs when light rays entering the eye focus behind the retina, rather than directly on it. The eyeball of a farsighted person is shorter than normal. Sometimes people confuse hyperopia with Presbyopia, which also is a difficulty in seeing up close, but has a different cause.
Farsightedness can be corrected with spectacles or contact lenses to change the way light rays bend into the eyes. If your spectacles or contact lens prescription begins with plus numbers, like +2.50, you are farsighted. You may need to wear your spectacles or contacts all the time, or only when reading, working on a computer, or doing other close-up work.
