Dazzle-free mirror with photocell in a non-dazzle-free portion

A dazzle-free reflection mirror having a mirror surface, comprising:

• an electro-optical element of which transparency is changed by applying an electric field thereto extending over a lower portion of said mirror surface to be dazzle-free, a remaining portion of said mirror surface being non-dazzle-free;
• means for reflecting light provided behind said electro-optical element and said non-dazzle-free portion, at least the portion of said reflection means provided behind said non-dazzle-free portion being a translucent mirror layer passing a part of incident light therethrough;
• means, provided behind said translucent mirror layer, for detecting light incident through said non-dazzle-free portion and said translucent mirror layer;
• and
• means for applying an electric field to said electro-optical element to effectuate the dazzle-free operation of said dazzle-free portion in response to the detection of said light detecting means, whereby only said dazzle-free portion of said mirror surface can assume a dazzle-free condition.
