  • Peripheral vision loss - loss of side vision in either one or both eyes or lose of top and bottom vision in one or both eyes

  • Night blindness - the inability to see in poorly lit areas such as outside at night or in movie theaters

  • Blurry  - objects near and far are out of focus

  • hazy vision - the field of vision appears to be covered in a film or haze

Risk Factors For Low Vision

While anyone can experience low vision, it is most common in adults over age 45 and is even more common in adults over 75.  In fact, one in 6 aged 45+ have this condition and one in 4 adults over 75 have low vision.  Low vision is caused by a variety of eye conditions and eye injuries.  For example, diabetes may cause diabetic retinopathy which will place an individual at an increased risk of developing low vision.  

Other common causes of low vision are macular degeneration, cataracts, and glaucoma. Macular degeneration is a disorder that affects the retina and its cause is largely unknown, but age is a primary contributor as is smoking and nutrition. A cataract is when part of all of the lens in the eye is clouded. They can be caused by genetics, long term exposure to UV radiation, and disease. A glaucoma occurs when there is increased pressure in the eye caused by problems with fluid drainage.  A glaucoma will then cause damage to the optic nerve and the first signs of a glaucoma are difficulty with night vision and loss or change in peripheral vision.

Diagnosing Low Vision

Low vision is defined as having less than 20/70 eyesight, therefore a standard dilated eye exam can diagnose the condition.  This exam is painless and your eye care provider will ask you to read letters while they conduct a visual evaluation.  They may also check your peripheral vision during the exam. Your doctor may also dilate your eyes to check for eye diseases and conditions that cause low vision.  If you are older than 60, or African American and over 40, or have a family history of glaucoma you should get a low vision exam every one to two years.
