Does Your Vision Suffer When Driving At Night?
It’s not uncommon for vision to weaken with age, especially at night, but this is a dangerous trend. If your own diminishing vision makes it difficult to drive at night, it’s important to see your eye doctor for the right treatment.
Why Is Driving At Night More Challenging?
Night time driving isn’t easy. Sudden glares of light from cars, street lamps, and traffic signals force the eyes to constantly adjust to new levels of light with only split seconds in-between. This places strain on the eyes and makes even common routes feel unfamiliar. Many people find that their daytime vision remains strong while their nighttime vision weakens.
Th eyes actually work by sensing light with two different types of cells called rods and cones. While cones thrive in strong sunlight, rods prefer low light. This means that as the rods weaken with age or due to another health condition, your night vision will suffer. In addition, since the eyes contain fewer rod cells than cone cells, and since the light receptors within rods can’t regenerate as rapidly, night vision – especially while driving – can become challenging.
