Hyperopia, commonly known as farsightedness, is a vision defect (ametropia) that often presents no obvious symptoms in the early stages but can cause significant visual fatigue. In a farsighted eye, light rays do not focus on the retina, but rather "behind" it.
This phenomenon is primarily due to an eyeball that is shorter than normal (axial hyperopia) or a cornea that is excessively flat.
Adults often compensate for hyperopia through accommodation, but as they age (especially after 40), this effort becomes more difficult, leading to:
Children have very flexible eyes that can mask the defect. However, if severe and left uncorrected, hyperopia can cause:
Correct eye function depends on four main components working in harmony:
In hyperopia, if the cornea is too flat or the lens is too thin, light falls behind the retina, making near objects appear blurry.
Today, hyperopia can be successfully managed through various options depending on your lifestyle and the severity of the defect:
Glasses use convex lenses (thinner at the edges, thicker in the center) to bring the focus exactly back to the retina. This is the simplest and safest solution.
Contacts offer a wider field of vision and are ideal for active individuals. However, they require strict hygiene to avoid eye infections.
Procedures such as PRK, Lasek, or Lasik allow the cornea's curvature to be reshaped, eliminating or drastically reducing the need for glasses.
