Quick! Put your hands on your head. Are your glasses there? Grab your neck — are they dangling there? Now, hold your electric bill four feet from your face and try to read it.... Welcome to the midlife version of Simon Says, a nearly universal condition known as presbyopia, which translates roughly to "elderly eye" (as if crow's feet weren't enough).

  • About 3.3 to 4.1 million Americans ages 40 or older are blind or have low vision. This is about 1 in every 28 people. By 2020, that number could be 5.5 million -- a 60% increase.

If there are no issues, you should then see your doctor every 2 to 4 years until you are 54. Afterwards, visits should be more frequent – every 1 to three 3 years.

Symptoms of AMD

AMD is painless. It may worsen slowly or rapidly. Dry AMD may affect central vision within a few years. Wet AMD can cause sudden and dramatic changes in vision. In either case, early detection and treatment are key to slowing vision loss. See your eye doctor right away if you notice:

  • Straight lines appearing wavy, a symptom of wet AMD
  • Blurred central vision, the most common dry AMD symptom
  • Trouble seeing things in the distance
  • Difficulty seeing details, like faces or words on a page
  • Dark or "blank" spots blocking your central vision
