Hyperopia is a refractive error that causes farsightedness. The anatomy of the eye is such that light focuses behind the retina creating a blurred image when looking at objects up close. Approximately 1 in 2 people have some degree of hyperopia, which may also cause headaches and eyestrain. Hyperopia is typically genetic and usually develops in childhood. The condition is easily diagnosed during a comprehensive eye exam and treated with glasses, contact lenses, or refractive surgery
