Low Vision

Low vision is the loss of sight that cannot be corrected with eyeglasses, contact lenses, or surgery. Low vision is different than blindness because, with low vision, you will still have sight. To be considered legally blind, your vision would need to be 20/200 with correction. If your field of view is restricted to less than 20 degrees wide, you would also be considered legally blind. If you have low vision and you are partially sighted, your prescription would be between 20/40 and 20/200. Our staff at Dr. Dorothy Park & Associates in Columbia, SC, can perform an eye examination and determine if you have low vision.

What Are the Types Of Low Vision?

There are a few types of low vision. These include:

  • Loss of central vision: This type is characterized by a blind spot right in the center of your field of vision.
  • Loss of peripheral vision: This is characterized by a loss of vision on either side, above, or below your field of vision.
  • Blurry vision: This is when objects both up close and far away are out of focus.
  • Hazy vision: This is characterized when the objects in your field of view appear to have a glare or a film.
  • Night blindness: This occurs when your vision is poor in dark places.

What Causes Low Vision?

There is often a medical reason for your low vision. These include:

  • Glaucoma
  • Macular degeneration
  • Diabetes
  • Cancer of the eye
  • Stoke
  • Eye trauma
  • Brain injury

How Is Low Vision Diagnosed?

Low vision can be diagnosed during an annual eye exam. If your vision is making it difficult to handle everyday tasks, you will need an eye exam. Your eye care professional will use special charts, special lighting, and magnifiers to test your visual acuity, your visual field, and your depth perception.

How Is Low Vision Treated?

Since low vision cannot be corrected by traditional eyeglasses, contact lenses, or surgery, you would need to rely on low vision aids to help you to see correctly. If your low vision is caused by diabetes, keeping your blood sugar can reverse the condition. If cataracts are the cause of your low vision, having the cataract removed will restore your vision. If the condition cannot be treated, there are still ways that you can improve your vision a bit so that you can still handle everyday tasks. A few of the most common low vision aids include:

  • Telescopic glasses
  • Light filtering lenses
  • Handheld magnifiers
  • Closed-circuit television
  • Magnifiers
  • Reading prisms
  • Text reading software
  • Large print publications
  • Books on tape
  • Talking clocks and watches
