Adults over the age of 40 who require multifocal contact lenses in order to correct near-sighted vision may have difficulty driving at night than their glasses-wearing counterparts.

According to a new preliminary study that observed the driving skills of 11 adults between the ages of 45 and 64 years of age, those wearing contact lenses drove at slower speeds; however, they had greater difficulty with identifying potential road hazards. Study participants drove on a closed circuit driving track at night and were evaluated in five areas including road sign recognition and lane keeping.

The author of the study, Byoung Sun Chu, PhD, suggested one alternative: practitioners should prescribe multifocal contact lenses for daytime use and a different correction for driving at night.
