No.1 in Rear-View Mirrors - market share - Murakami -

The hydrophilicity function processing is given to the left half of the mirror, and the right half is a usual mirror.

When rain drops accumulate on a normal rear-view mirror, the driver suffers from decreased visibility. Our HCM mirrors solve this problem by transforming the many distortive water droplets into a single optically consistent film of water. Our special hydrophilic coating spreads this film of water evenly over the entire mirror surface resulting in improved visibility.
