An electro-optic device is disclosed having a self-cleaning, hydrophilic optical
coating. The electro-optic device preferably forms an external rearview mirror
for a vehicle. The optical coating preferably includes photocatalytic layer(s),
a hydrophilic layer, and a color suppression coating. The electro-optic device
is preferably an electrochromic mirror. The disclosed optical coating exhibits
a reflectance at the front surface of the reflective element that is less than
about 20 percent, and has sufficient hydrophilic properties such that water droplets
on a front surface of the optical coating exhibit a contact angle of less than
about 20. The mirror exhibits a C* value of less than 25.
