Does the immune system recognize your eyes?

Researchers have found that bananas have carotenoid — a compound that turn fruits and vegetables red, orange or yellow and are converted into vitamin A, important precursors for eye health — in the liver.
Are floaters a sign of brain tumor?
Hearing and vision loss- A tumor that is located near the optical nerve could cause blurred vision, double vision or loss of peripheral vision. Depending on the size and location of a tumor, abnormal eye movements and other vision changes like seeing floating spots or shapes knows as an “aura” may result.
Do we see with our eyes or brain?
Our eyes do a really good job of capturing light from objects around us and transforming that into information used by our brains, but our eyes don’t actually “see” anything. That part is done by our visual cortex. Our eyes being slightly apart creates an image that needs to be corrected.
Can a routine eye test detect a brain Tumour?
A regular, routine eye test can sometimes detect eye problems that indicate the presence of a brain tumour before any symptoms become obvious. An eye test is particularly good at identifying any swelling of the optic disc (a condition called papilloedema) and can also identify when there is pressure on the optic nerve.
What type of brain tumor affects vision?
A tumour in the occipital lobe causes difficulties with vision, such as visual loss, or identifying objects or colours. Alternatively, it may cause loss of vision on one side.
Can humans see without eyes?
