What is Long-sight (or Hyperopia/Farsightedness)?

Long-sight/farsight or hyperopia results from either or combination of the following:

  • the eye is too small for the focusing power of the eye, or
  • the focusing power of the eye is too strong

This is opposite to short-sight or myopia.

Hyperopia can come in two forms:

  • Latent Hyperopia: there are no symptoms and vision is normal
  • Manifest Hyperopia: vision is blurry and/or headaches are present when reading or performing up-close tasks; vision can be blurry and/or headaches can occur for distance as well

Long-sight can be corrected by

Most people have a small degree of long-sight (or hyperopia) and have no issues at all. This is because their form of long-sight is latent. The lens in the eye is able to increase in power, resulting in sharp focus and with no headaches or eye strain.

However with age, when the lens of the eye becomes less able to change focus (known as presbyopia) or the degree of long-sight is too much, this can result in the condition becoming manifest.

In order to remedy this, the light entering the eye must focus on to the back of the eye, known as the retina.

This most common ways to achieve this are by using:

  • Glasses
  • Contact Lenses

Other methods involve temporarily or permanent changing the shape the the eye to correct focus, and these include:

  • Orthokeratology
  • Referral for surgical correction
