To evaluate improvement in subject’s visual performance under simulated night driving conditions with and without glare while wearing wavefront guided spectacles versus conventional lenses.
Double masked study design using identical frames for both pair of spectsclaes. Night driving visibility detection and identification with and without glare was used to assess driving performance using a FDA validated Night Driving Simulator.
27 subjects ages 18 to 64 years completed the study. Refractive errors ranging from + 1.20D to - 5.75D sphere with up to -2.5D astigmatism. Statistical significant improvement was seen in 10 of the 12 test segments while wearing the wavefront guided lenses over the conventional lenses. P values ranged from 0.0006 to 0.0461 for the 10 statistically significant segments using t-test for paired data, α = 0.05.
Wavefront Guided lenses improve reaction time over traditional lenses in detecting and identifying normal road signs and pedestrian hazards while driving in simulated night time driving situations with glare conditions.
