Of course for communication colored irises are important. However:
Visible light varies in color red orange yellow green blue indigo violet, in decreasing wavelength.
The smaller something is the more it gets deflected. The shorter the wavelength of light the more it is refracted.
The higher the latitude the shallower the angle at which sunlight hits Earth.
The higher the latitude the less direct sunlight and the more deflected sunlight hits the ground.
The cloudier the sky, the more refraction = the bluer the light.
The higher the latitude the more of the available food is in the water.
The higher the latitude the more important the moderating effect on climate of the ocean.
The closer to the ocean, the more clouds.
The higher the latitude the more snow on the ground.
Of the light hitting snow and water, blue is more reflected. They also reflect the sky color.
Blue eyes are adaptive to high latitude by the ocean, where they will absorb the scarce red end light but reflect excess blue light.
