Multifocal contact lenses may reduce vision for night driving
A new study suggests that older adults who wear multifocal contact lenses to correct problems with near vision, a very common condition that increases with age, may have greater difficulty driving at night than their counterparts who wear glasses. A…
The zebrafish’s neural circuit prevents it from biting off more than it can chew
