Abstract

|
|
Purpose: This study investigated the dynamics of accommodation and pupil size when wearing night driving lenses and measured the change in visual function under simulated night driving lighting conditions.
Methods: A total of 17 (23.06±0.51) students with no history of ocular surgery participated in the study. All participants had normal binocular vision and more than 0.8 visual acuity. The dynamics of accommodation and pupil size when wearing night driving lenses were measured using WAM-5500. Visual acuity and contrast sensitivity were also measured.
Results: There were no significant changes in the accommodation and pupil size when wearing different types of night driving lenses. Further, no difference was noted in the visual function.
Conclusions: Night driving lenses used in this study had no effect on the accommodation and pupil size. Therefore, any deterioration in visual function or discomfort during night driving may require solutions apart from wearing night driving lenses.
