Study Summary
It is a common clinical practice to leave small amounts of astigmatism uncorrected in contact lens wearers. Therefore, some drivers who have astigmatism and wear contact lenses may experience blur while driving. The purpose of this study is to determine if correcting small amounts of astigmatism with contact lenses will improve driving safety.
Primary Outcome
This scale measures driving performance in the simulator. It is the sum of the z scores from 15 different driving simulator variables related to braking, steering, speed control and judgment. The scale has no fixed limits. A score of 0 indicates average performance. Higher scores indicate better performance.
Interventions
- DEVICE Placebo Lenses
- DEVICE Spherical Lenses
- DEVICE Toric Lenses
