Enhanced vision for driving

A system for imposing a filter between a vehicle driver's eyes and a source of light, comprising:

• at least one detector facing inward towards a position of the head of the vehicle driver and arranged to obtain images of elements associated with the eyes of the driver;
• processor means coupled to said at least one detector and arranged to determine the location of the drivers eyes based on analysis of the images obtained by said at least one detector and to obtain information about objects exterior of the vehicle providing sources of light from the images obtained by said at least one detector based only on reflections off of surfaces associated with the driver's eyes;
• and
• filter means coupled to said processor means for imposing a filter between the sources of light and the driver's eyes based on the location of the driver's eyes as determined by said processor means and the information about the exterior objects providing the sources of light obtained by said processor means.
