Condition

Farsightedness

(Hyperopia)

Definition

People with farsightedness have a hard time seeing close objects. Images are blurred. People with severe symptoms may have trouble seeing objects both far and near.

Causes

This problem happens when the shape of the eye does not bend light correctly. The eyeball is too short for light rays to clearly focus on the retina.

It may also be caused by a problem with the shape of the cornea or lens.

Interior of the Eye.

Light rays are precisely focused on the retina (orange) in good vision.

Risk Factors

This problem is more common in people who have other family members who are farsighted.

Symptoms

Problems may be:

  • Trouble focusing on objects that are close
  • Blurred eyesight
  • Headache
  • A feeling of tiredness in the eyes

Young adults with farsightedness often do not have symptoms. However, they may need reading glasses at an earlier age.

Diagnosis

The doctor will ask about your symptoms and health history. Your vision will be tested. This is often enough to make the diagnosis. You may also be referred to a doctor who treats eyes.

Treatment

The goal of treatment is to improve vision. Options are:

  • Corrective lenses, such as eyeglasses or contacts
  • Surgery to change the shape of the eye to improve its ability to focus light

Prevention

There are no known guidelines to prevent this health problem.
