Why does the iris of the eye go white when blinded via injury?
In: Biology
The pupil is not a thing, it’s a hole. If the normally clear fluid inside were to cloud up, it looks white rather than black. The iris is very thin, having a milky or white layer behind it makes it look faded out.
Humans have a very effective way of healing. Our scar tissue forms much quicker than other organisms. However, this comes at the cost at being a rush job. That’s why scars form big lumps; your body is just stopping the wound as quickly as possible without caring about what it was like before.
This is what happens in the eye. If you get an injury, or your body perceived an injury, it makes scar tissue. That scar tissue serves one purpose, healing the injury ASAP. Since the body doesn’t care about the functionality of the tissue, instead of the clear lens or tissue you had before, you get whatever the body gives you; a white blob.
