Presbyopic drivers' vision through a convex rear view mirror.
BACKGROUND
Monovision is a commonly used modality for the presbyope who wants to wear contact lenses. If the add for near vision is in the left eye, driving an automobile creates a circumstance whereby the lens wearer cannot obtain a clear image in that eye of distant objects seen in the driver's side outside rear view mirror.


METHODS
We have discovered that a stick-on convex mirror eliminates this problem by neutralizing either some or all of the power of the add.


RESULTS
The driver wearing an add in the left eye can then obtain a clear image in that eye of objects behind and to the side of the automobile.
