Evaluation of the Bausch & Lomb PureVision Under Nighttime Driving Conditions

The objective of this study is to quantify differences in nighttime driving performance between the Bausch \& Lomb PureVision™ aspheric contact lenses and a conventional spherical contact lens. The primary aims of this study are to determine the differences between B\&L PureVision™ aspheric contact lenses and a conventional spherical contact lens in visual performance measures associated with driving, such as number of objects seen. The secondary aims of this study are to determine differences between B\&L PureVision™ aspheric contact lenses and a conventional spherical contact lens in driving performance measures such as number of objects hit.
