Normal Vision Changes

Just as the body changes with age, our eyes undergo changes, too. Our eyes function differently in our 60s than they did in our 30s. Such changes in vision are normal, offer few serious risks, are not caused by disease or illness, and, in general, can be corrected with eyeglasses, contact lenses, or surgery. Other changes in vision, however, can be a sign of eye disease.

Although many age-related vision changes are normal, they can cause problems by interfering with a wide range of everyday activities.

How do you know the difference between a "normal" change in vision and a change that is more serious? To determine the answer, your doctor will want to know your specific symptoms; thus, the best way to answer this question is to visit your eye care professional.

Vision Changes in the Aging Eye

The most common age-related vision changes and their effects on everyday activities can include the following:

  • Increased sensitivity to glare

    glareBeing able to see clearly when exposed to reflected light or bright sunlight—especially outdoors on a sunny day or in a hallway with highly polished floors—requires filtered lenses or other adaptations to control glare and to see the environment clearly.
  • Increased lighting requirements

    lighting requirementMost older adults require three to four times more light than they did previously to perform many everyday activities. Seeing clearly enough to read, write, sew, or perform home repairs usually requires a brighter, more focused light in addition to reading glasses or bifocals.
  • More time required to adjust to bright light and/or darkness

    light adjustmentAdjusting to changes in light levels between bright and dark areas—such as leaving a dim building lobby and walking outside into bright sunlight or moving out of a restaurant with dim lighting into daylight—can take two to three times longer than it used to.
  • Reduced contrast sensitivity

  • Decreased ability to judge depth perception

    depth perceptionDifficulties judging distances accurately—the height of a step or curb, or the depth of a bathtub, for example—requires close attention to safety cues such as color, contrast, and lighting. Shadows and shadow patterns may be incorrectly interpreted as drop-offs or obstacles.
  • Decreased ability to focus close up

    focus problemAs the eye muscles that control the switching of focus from far to near begin to lose flexibility, it becomes more difficult to focus on things close up. Reading a newspaper, writing, or sewing usually require reading glasses to accommodate this change in focus.
  • Decreased color sensitivity

    color discriminationTelling certain colors apart becomes more difficult when matching clothing or playing card games. In particular, it is often difficult to distinguish navy blue from brown or black; blue from green or purple; and pink from yellow or pale green.

Why do I see better on some days than on others?

All of us experience good days and bad days, in terms of our general health. However, if you experience any of the following vision changes, it's recommended that you contact your eye doctor immediately:

  • Sudden hazy, blurred, or double vision
  • Recurrent pain in or around the eye
  • Seeing flashes of light or sudden bright floating spots
  • Seeing rainbows or halos around lights
  • Seeing floating "spider webs"
  • Seeing a "curtain coming down" over one eye
  • Sensing a "cup filling up with ink" in one eye
  • Unusual, even painful, sensitivity to light or glare
  • Swollen, red eyes
  • Changes in the color of the iris
  • Sudden development of persistent floaters
  • Itching, burning, or a heavy discharge in the eyes

At any age, it's important to have your eyes checked regularly. If symptoms or concerns arise, contact your eye care professional as soon as possible.
