Question about the Eye?

Question

(human eye)

does the eye clean itself naturally?

as in if you get a piece of sediment in there will the eye like take it out by itself or something?

how?

Answer 1

Yes.  The majority of foreign objects that come in contact with the eye are removed by a combination of tearing, blinking, and encapsulation with mucous.  I have seen some foreign objects, though, that become imbedded or adhered (such as a something with a concave shape like a seed coating) that the eye is not able to remove.  In these situations, the immune system comes into play and attempts to wall off the foreign object and form a granuloma around the object.
