Thus, the visual illusion produced by pressing the eyeball might be regarded not only as the result of the organic law of the "specific energy" of the nerves, but, with almost equal appropriateness, as the consequence of an exceptional state of things in the environment, namely, the pressure of a body on the retina.
And once, just as I was looking, it shut and opened at me slowly, like the deliberate drooping and rising of the lid upon a white eyeball. Somebody had come in. We watched side by side. Only one. Would he go out? The point of light, like a white star setting in a coal-black firmament, remained uneclipsed. Whoever had entered was in no haste to leave.
Unlike Harran, he resembled his mother, but he was much darker than Annie Derrick and his eyes were much fuller, the eyeball protruding, giving him a pop-eyed, foreign expression, quite unusual and unexpected.
The full, clear forehead, well framed by abundant black hair, was dreamy, and did not contradict the character of the face, which was altogether melancholy. The prominent arch of the upper eyelid, though very beautifully cut, overshadowed the glance of the eye, and added a physical sadness, if we may so call it, produced by the droop of the lid over the eyeball.
Much smoking of tobacco may hurt the nerve of sight and in a few cases it has made men blind. Many boys have weakened their eyes by the use of cigarettes. Name the chief sense organs. Of what use are the eyelids and tears? Name four parts of the eyeball. What is the iris? Of what use is the lens? What moves the eyeball? When do children get weak eyes? How are the eyes often hurt?
The sclerotic coat covers the greater portion of the larger spherical segment and is recognized in front as "the white of the eye." It is composed mainly of fibrous connective tissue and is dense, opaque, and tough. It preserves the form of the eyeball and protects the portions within.
Rider speaks of the lodgment of a fragment of a copper percussion cap in the left eye, back of the inner ciliary margin of the iris, for thirty-five years; and Bartholinus mentions a thorn in the canthus for thirty years. Jacob reports a case in which a chip of iron remained in the eyeball twenty-eight years without giving indications for removal.
I could not help laughing at the recollection, but I kept an anxious lookout toward the west. Three weeks' imprisonment in Sark now would be a bore. But the fog remained almost stationary in the front of Guernsey, and the round red eyeball of the sun glared after us as we ran nearer and nearer to Sark. The tide was with us, and carried us on it buoyantly.
When the eyeball is cut or pierced, if the cut be deep or large, a surgeon must deal with it. But if small, a drop or two of castor oil let fall into the eye will often be all that is required. Where inflammation comes on, the tepid pouring recommended below for bad eyes will greatly help. If more severe, the treatment for inflamed eyes may be given.
And Kilwich caught it, and threw it vigorously, and wounded him through the eyeball. "A cursed ungentle son-in-law, truly! As long as I remain alive, my eyesight will be the worse. Whenever I go against the wind, my eyes will water; and peradventure my head will burn, and I shall have a giddiness every new moon. Like the bite of a mad dog is the stroke of this poisoned iron.
