"Why has not man a microscopic eye? For this plain reason, Man is not a Fly. Say, what the use, were finer optics givn, T inspect a mite, not comprehend the heavn?"

An eye is a sensory organ that allows an organism to perceive visual information. It detects light and converts it into electro-chemical impulses in neurons (neurones). It is part of an organism's visual system.

"Ladies, whose bright eyes Rain influence."
"The night has a thousand eyes, And the day but one; Yet the light of the bright world dies With the dying sun."
"In every object there is inexhaustible meaning; the eye sees in it what the eye brings means of seeing."
"You have seen Sunshine and rain at once. * * * those happy smilets, That playd on her ripe lip, seemd not to know What guests were in her eyes; which parted thence, As pearls from diamonds droppd."
"Her eye (Im very fond of handsome eyes) Was large and dark, suppressing half its fire Until she spoke, then through its soft disguise Flashd an expression more of pride than ire, And love than either; and there would arise, A something in them which was not desire, But would have been, perhaps, but for the soul, Which struggled through and chastend down the whole."
