Farsightedness

(Hyperopia)

Definition

People with farsightedness have a hard time seeing close objects. Images are blurred. In severe cases, they can have trouble seeing objects both far and near.

Causes    TOP

With farsightedness, 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 your cornea or lens.

Risk Factors    TOP

You are more likely to be farsighted if others in your family have same visions problems.

Symptoms    TOP

Symptoms may include:

  • Difficulty focusing on objects up close
  • Blurred vision
  • Headache
  • Eyestrain

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

Diagnosis    TOP

A specialist will ask about your symptoms and past health. You will be given an eye exam. This will help rule out any other issues. Your vision will be tested with various lenses. This will help to see how affected the vision is.

Treatment    TOP

Talk with your doctor about the best treatment plan for you. Options include:

Corrective Lenses

Eyeglasses or contact lenses can return your vision to normal or near normal. Your prescription may change over time. It is important to go to regular eye exams. The wrong prescription will decrease your ability to see well and may cause headaches.

Refractive Surgery

This type of surgery can changes the shape of the eye. It will improve the eye's ability to focus light. It is not an appropriate options for everyone. Many of these procedures are done using lasers.

Prevention    TOP

There are no current guidelines to prevent farsightedness.
