What happens to our eyes as we get older?

  • As we age our retina becomes less sensitive to light. More light makes it easier to see and drive and older drivers require significantly more light than younger drivers.
  • Our ability to change our focus starts to slow down around age 40. A driver over the age of 40 can take at least a second longer to refocus than a younger driver takes (such as when looking up from the dash to the road ahead.)
  • We become more sensitive to glare because the lenses of our eyes thicken and the pupils become smaller. A 55-year old takes eight times longer to recover from glare than a 17-year old.
  • Peripheral vision narrows and depth perception declines as we age. Depth perception is important because we use it to judge how fast other cars are moving.
  • Colours become more difficult to see - especially moving Reds as used in brake lights and traffic lights.
