Do mountain goats have good vision?

Take a close look at a house cat’s eyes and you’ll see pupils that look like vertical slits. But a tiger has round pupils — like humans do. And the eyes of other animals, like goats and horses, have slits that are horizontal. Scientists have now done the first comprehensive study of these three kinds of pupils.
What are rectangular eyes called?
The goat eyes are referred to as strange because they have rectangular or horizontal pupils.
Why do some goats have horizontal pupils?

What does goats vision look like?
Goats are dichromatic, so they have two cones in their eyes. One picks up on blue light, and the other picks up on green light. They lack the cone that is sensitive to the different tones of red. So, while they can see greens and blues just fine, they struggle to see the difference between greens and reds.
What animals have horizontal eyes?
Goats, sheep, deer, horses, frogs and toads have horizontal pupils. One advantage to slit-like pupils is that they allow the iris to contract and expand more dramatically. This is a useful trait for nocturnal species whose eyes are designed for low-light levels. It also protects their eyes from the bright light of day.

Why do goats eyes look weird?

Why do some goats have rectangular pupils?
Why do goats have rectangular eyes?
Thus, here’s a guide on why goats have rectangular eyes. The pupils of goats’ eyes are horizontal slits because it allows them to have a larger field of vision on the horizontal plane. Thus, their vision is similar to a panoramic image in which all horizontal distances are clear, irrespective of where they’re focusing.
How do goats see color?
Goats eyes pick up light ranging from the violet/blue through green to yellow/orange part of the spectrum due to two types of color receptors in their retina, called cones. One type is most sensitive to blue light, while the other to green.
