Dogs with blue eyes in pictures are blind?

(this is why dogs have blue eyes.) --There, is a lot of dogs with blue eyes, Not only Siberian Huskies--

Primarily, eye color is determined by genetics. Although irises come in different colors, they actually only contain brown pigment. When an iris has alot of brown pigment, the eyes appear brown or dark. When the amount of brown pigment is small and is only on the back surface of the iris, the shorter wavelengths of light are scattered from the unpigmented portions and eyes appear blue, green or gray. This effect is similar to the scattering of light that makes the sky appear blue. The iris pigment may not be fully developed at birth so alot of young animals eyes may appear blue or gray at first until their pigmentation fully develops. Sometimes, one eye may contain more pigmentation than the other, making the eye colors within one individual distinctly different. Siberian Huskies are one of the breeds that commonly display this trait...But other breeds can can too But Siberian Huskies is (Most) common to display this trait.
