Eyes

The eyes are organs. They detect light, regulate the light through a diaphragm, focuses it through adjustable lenses and converts them into electo-chemical impulses in our neurons by photoreceptor cells called rods and cones. The image is converted into a set of electrical signals that are transmitted to the brain via neural pathways that connect the eye to the optic nerve and visual cortex of the brain. In short, eyes are very complex optical systems that convert light to distinguish objects and movement around us.

And unless the mother has any red hair in her family genealogy I d go for the baby having brown hair with maybe slight reddening as an undertone. As for eye colour green and blue are recessive though hazel is a mix of green and brown. So 75% brown green mix 20% green slight brown and 5 % green.

A bee doesn't have three eyes, it has five! It has two compound eyes, which are its organs of vision, and on the top of its head (slightly forward of the top in a drone) are three simple eyes, called ocelli, which are set out in a triangle. The ocelli don't form images, they are simply light receptors. Although their purpose is not fully understood, it is thought they help the bee to orient itself when flying.

What does it mean if your hamster sometimes has 2 red eyes or 2 black eyes?

it probably has an abcess in its eye, and you should go to the vet ASAP. the least that could happen is the eye could be taken out. if you don't want to do that to your hamster, or put him through any pain, and you don't take him to the vets, then it is a criminal offence to keep him the way he is. he could be in a lot of pain already and can probably not see through that eye any more, so when you take him to the vet, you will be relieving him of the pain. this will n ot effect him, with only one eye, as hamsters have very poor vision as it is.

Can a brown eyed mother and a grey eyed father have grey eyed kids?

Babies eye colors change, for instance i know someone who started out with piercing blue eyes before turning hazel, and neither their parents nor their siblings had blue eyes.

If the babies eye color stays the same both parents could simply have a recessive gene for grey eyes. This means that the gene exists in their bodies but is not strong enough by itself to affect eye color but when paired with another recessive gene it can become the dominate gene.
