Low vision is an eye condition that cannot be completely corrected using standard eyeglasses, contact lenses, medication, or surgery. It significantly hinders daily activities, including reading, recognizing faces, and navigating the environment.

It is often caused by underlying eye conditions such as age-related macular degeneration (AMD), glaucoma, diabetic retinopathy, and cataracts.

Low Vision in the United States: The Data

Understanding the prevalence of low vision in the United States sheds light on the scope of this condition. Based on information from the National Eye Institute (NEI) and Centers for Disease Control and Prevention (CDC):

  • Approximately 2.9 million Americans aged 40 and older have low vision.
  • The risk of low vision increases with age, with 1 in 28 Americans aged 40 and older experiencing this condition.
  • Underlying health conditions such as diabetes contribute significantly to the prevalence of low vision.

Low vision can be caused by a variety of eye conditions and diseases:

1. Age-Related Macular Degeneration (AMD)

Age-related macular degeneration – AMD is a leading cause of low vision among older adults. The condition affects the macula, which results in a gradual loss of vision in the center of the visual field. Please check https://lowvisionaids.org/macular-degeneration-amd/

2. Glaucoma

Glaucoma can result in peripheral vision loss and, if left untreated, may lead to blindness.

3. Diabetic Retinopathy

A complication of diabetes, diabetic retinopathy can cause damage to blood vessels in the retina, leading to vision problems.

4. Cataracts

Cataracts occur when the eye’s natural lens becomes cloudy, causing vision to become blurred or dimmed.

5. Retinitis Pigmentosa

This disorder is genetic and affects the retina, causing tunnel vision and difficulty seeing in low light.
