Furthermore, in technique scheme, described pattern element dense degree be from the edge, the lower left corner of eyeglass to central area gradually from intensive become sparse.
Furthermore, in technique scheme, described pattern element is dot pattern.
Furthermore, in technique scheme, described pattern element is strip pattern.
Furthermore, in technique scheme, described pattern element is blocky.
Furthermore, in technique scheme, described governor circuit is provided with the optical receiver for detecting high light signal, this optical receiver is positioned at mirror holder center position area.
The utility model designs according to traffic rules, according to the regulation that current traffic law " is kept to the right ", when vehicle meeting, high light is from lower left, the high light that dead ahead and right are not dazzle the eyes, as long as so carry out some suitable covering to the region of lower left, just greatly light intensity can be reduced, play abblendbar effect.The utility model is exactly become some pattern elements of sparse distribution from intensive at the edge, the lower left corner of eyeglass gradually to central area, when meeting, high light number occurs, optical receiver in governor circuit sends electric signal while receiving optical signals, pattern element on eyeglass is dimmed, whole like this eyeglass will be formed in lower left according to gradual change law region dimmed gradually, thus the personnel of driving that effectively strick precaution high light causes dazzle the eyes; And when there not being high light, lens recovers light normally through state (pattern element recovers transparent), penetrability gets back to normal condition equally.
