Vision Functions

Our ability to see clearly when driving can certainly change with age. Limited vision is a very common reason that seniors are referred to a vision specialist, drive with restricted driver license, or have their driver privilege revoked. Some age-related vision changes that commonly affect seniors are:

  • Not being able to see as clearly as before
  • Having difficulty seeing an object up close
  • Needing more light
  • Noticing changes in color perception
  • Having more difficulty seeing in the dark
  • Being less able to adapt to glare
  • Experiencing a loss of side vision

Effects on Driving Ability

Age-related vision conditions may cause some of the following problems:

  • Bright sunlight or the headlights of oncoming traffic may impede your vision
  • It becomes more difficult to judge distances and speed
  • It becomes more difficult to distinguish road signs and to gauge oncoming traffic
  • Your eyes get tired easily making it more difficult to concentrate
  • Left-hand turns become difficult
  • Assessing right-of-way situations may become more difficult
  • Blurred vision may cause right-of-way problems

What you can do for safer driving:

  • Get regular eye exams
  • Limit yourself to daytime driving if you are having trouble seeing at night
  • Add a larger rearview mirror to increase your field of view
