Hyperopia, or farsightedness is a condition where far vision is relatively clear, yet close vision is blurry. Roughly 25% of the population is affected by this refractive error, characterized by difficulty focusing on objects that are up close. In a normal visual system, light passes through the cornea and lens and comes into focus at the retina; in a hyperopic eye, light comes into focus behind the retina. This occurs for one of two reasons: either the patient’s ocular axis is too short, or the corneal focusing power is too weak.
Like myopia, hyperopia is also an inherited condition. Most children are farsighted, yet they usually do not have experience blurry vision. Children’s eyes are able to bend the light rays and place them directly on the retina when focusing. As long as the farsightedness is not too severe, hyperopic children will have clear vision for seeing objects at a distance and up close. As the eye grows and becomes longer, hyperopia lessens.
Symptoms of hyperopia are similar to myopia, only with close vision. Individuals may experience squinting, eye fatigue and headaches from trying to focus on close vision. The best way to diagnose hyperopia is by having an eye exam. Your eye care professional will use an instrument, called a phoropter to measure the degree of the refractive error. Then a prescription can be written for glasses based off of the phoropter measurement.
