1. A method of reducing glare from oncoming vehicle headlights, said method comprising:
- Providing a first attachment for a vehicle front windshield, said vehicle having a driver'"'"'s side and a passenger side, said first attachment comprising;
A slatted blind having a plurality of horizontally-oriented slats extending between a headrail and a bottom rail, a flexible cord ladder connected between the headrail and bottom rail and supporting said slats, and an electric motor for rotation of said slats from opened to closed and from closed to open;
Securing said slatted blind with mounting means to an upper portion of the inside of the vehicle'"'"'s front windshield on the driver'"'"'s side such that the attachment has a width less than 30 percent of the horizontal width of the vehicle'"'"'s front windshield and the passenger side is uncovered;
Providing a second attachment for a vehicle front windshield, said second attachment comprising apparatus for automatically optically detecting when an oncoming vehicle with lit headlights is approaching the driver and automatically optically detecting when an oncoming vehicle with lit headlights is not approaching the driver;
Securing said second attachment with mounting means to the inside of the vehicle'"'"'s front windshield;
Driving said vehicle on a surface that can have oncoming traffic;
Automatically optically detecting when at least one oncoming vehicle with lit headlights is approaching the driver;
Automatically operating the electric motor to close the slats in response to automatically optically detecting when at least one oncoming vehicle with lit headlights is approaching the driver to prevent a driver from seeing through the slats when there is oncoming traffic with lit headlights approaching;
Automatically optically detecting when an oncoming vehicle with lit headlights is not approaching the driver;
Automatically operating the electric motor to open the slats in response to automatically optically detecting when an oncoming vehicle with lit headlights is not approaching the driver to allow a driver to see through the slats when there is no oncoming traffic with lit headlights approaching; and
Automatically repeating the automatic electric motor operating steps to open and close the slats while driving to accommodate varying oncoming traffic.

4. A glare blocking attachment for a vehicle having a driver'"'"'s side and a front windshield comprising:
-
(A) a slatted blind having a headrail and a bottom rail, flexible ladder means connected between said headrail and said bottom rail and a plurality of slats supported by said flexible ladder means, said slatted blind having a width less than 30 percent of the horizontal width of the vehicle'"'"'s front windshield; (B) electric motor rotation means mounted on said slatted blind for rotating said slats between open and closed positions; (C) first mounting means connected to said headrail for mounting said slatted blind on the inside of the front windshield on the driver'"'"'s side; (D) automatic detecting means for automatically detecting when there is an oncoming vehicle with glaring headlights and when there is no oncoming vehicle with glaring headlights; (E) second mounting means connected to said automatic detecting means for mounting said automatic detecting means on the inside of said front windshield; (F) whereby for nighttime driving said automatic detecting means operates said electric motor rotation means to open said slats when there is no oncoming vehicle with glaring headlights to allow a driver to see through said slatted blind and close said slats when there is an oncoming vehicle with glaring headlights to block the glare. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15)
