The first thing that came to my mind is cataracts. If your hamster is reasonably old/aged then (that is if hamsters can get cataracts) is is possibly this. I'm no professional but white spots are normally cataracts for all types of animals i.e dogs, goats, sheep, cats etc.
dehydration or going blind
There are several things that could be causing your hamster to have eye mucus. It could be from the bedding, a blocked tear duct, or it could just be because of the hamsters age; it is very common in older hamsters.
I think it's O.K. ^^^^ No usaully if hamsters have gray eyes only if their not white the rest am not sure but you might want to look at a hamster website to find out
Your pet maybe just cut it's eye while grooming its self
The closed eye should be wiped with a small piece of cotton wool soaked in luke warm water
Red eyed hamsters tend have poorer eyesight than black eye hamsters. Sometimes the hamsters eyes will change color an example: when a hamster is young it's eyes are red but when it gets older, it's eye color might change to black
The white part of the eye is the sclera, the colored part is the Iris, and the 'black dot' (which is actually just a hole reaching the back of the eye) is the pupil
The sclerotic is the white part of the eye. The iris is your eye color. The pupil is the black dot.
a bloodshot eye
no hamsters DO NOT have good eye site there use there whiskers to move and see better PS hamsters do not have eye bolls on the whiskers!!
Frogspawn is white, with a black dot in the middle, which makes it look like an eye!
Dogs have a third eyelid, called the nictitating membrane, that moves across the eye and gives additional protection to the cornea. It is a thin white membrane that is not usually visible. Having visible nictitating membranes, which appears to be what you are describing, can be a sign of ill health or problems with the eyes.
no way!!! there is special eye drops for hamsters at the pet shop
A typhoon is formed in earth also the white dot in the middle is called the eye a little fact!
They can get them, yes.
White eye
that means there's some thing stuck in its eye it happens to my hamster all the time or gunk from its eye hardened and when you pull it of it hurts the hamster I'm 80% sure that it has hardened gunk in its eye
The brown spot is the vestigial eye (represented by a white dot) located between the eyeballs.
