Elderly people with a certain type of blind spot were less likely to see
pedestrians in time to avoid hitting them in a driving simulator,
according to a new study.
“In the UK and parts of Europe, in order to have a license, you need to be tested for central blind spots, but in the U.S. you don’t have to,” lead author Matthew Bronstad told Reuters Health.
In his simulator test, people with blind spots often could not respond in time to a hazardous situation, said Bronstad, an instructor of ophthalmology at Harvard Medical School in Boston.
Blind spots at the center of the field of vision, or “central field loss,” are usually caused by macular degeneration, damage to the retina that occurs with age. About 1.75 million people in the U.S., most over 65 years old, have this kind of vision loss, according to a 2004 study.
