Bright-eye

“ The pupil of the eye dilates and contracts in proportion to the variety of bright and dark objects which are reflected in it. In this case nature has afforded compensation to the visual faculty by contracting the pupil of the eye when it is offended by excess of light and by causing it to dilate when offended by excess of darkness, like the opening of the purse. ”

“ The phenomena of ocular spectra and complementary colours experienced by every one forms a curious chapter in the history of those illusions which take their origin in the eye itself. Every one has noticed that after looking fixedly at a bright light or a striking colour for a few moments, the eye preserves an impression of the object for a certain time. A very light window looked at intently for several seconds will leave the impression of its cross-bars on the retina for several minutes, the colour of the image changing at every movement of the eye. ”

“ Light, which embellishes with so much magnificence a pure and serene sky, by means of innumerable bright starry orbs which are spread over it, sometimes, in a dark and cloudy sky, exhibits an ornament which, by its pomp, splendour and variety of colours, attracts the attention of every eye that has an opportunity of beholding it. ”

“ It would be worth the while to look closely into the eye which has been open and seeing at such hours, and in such solitudes, its dull, yellowish, greenish eye. Methinks my own soul must be a bright invisible green. ”

“ Luminosity, brightness in its higher intensities, whether the bright rays reach the eye directly or are reflected from a lustrous surface, this makes the first gladness of the eye, as it remains a chief source of the gladness of life. The feeling for color as such comes distinctly later. The first delight in colored objects is hardly distinguishable from the primordial delight in brightness. ”

“ Sweet light shall couch by flowery sapphire and blue violets, and dance with jocund joys where the white daisies tesselate the mead; then memory shall illuminate itself—turn out its store of images bright as at their creation; then shall the soul arrange its myriad hues of by-gone time; dwell over the glory of the spiritual scene, until, in extasy and grateful joy, a voice shall shout,—"How beautiful is Light." ”

“ The greatest distance creates white. The sun in the firmament may be viewed as the bright opening in a darkened chamber. Colours, are, therefore, nothing but images of the sun in darkness; self-manifestations of the sun in dark matter. A point of light thrown into darkness is colour. ”

“ No speech, no human voice, only the gentle clash of wooden dishes, the rustle of leaves, the gurgle of deep potations and the subdued sounds of gustation came from the place into which no human foot or eye dared intrude. At the conclusion of the affair, when Hiiaka, in priestly fashion, had pronounced the absolving word noa and the stewards were again at liberty to enter the precinct where the immortals had just now celebrated their symposium, it seemed, at first glance, as if nothing had been touched. ”

“ In which case we should have remained blind, or as bad as blind; brightness would have been in the eye when it ought to have been in the sun; greenness would have been in the retina when it ought to have been in the grass. A most wise provision of nature it certainly is, by which our visual sensations are disposed of in the right way before we obtain any knowledge of the eye. ”

“ It is impossible for any man, who can have an opinion worth anything on any question, not to have some kind of an opinion on the question of this war. I am not ashamed of my opinion, or of the sympathy which I feel, and have over and over again expressed, on the side of the free North. I cannot understand how any man witnessing what is enacting on the American continent can indulge in small cavils against the free people of the North, and close his eye entirely to the enormity of the purposes of the South. ”

“ The Color Wheel and Maxwell Disks.
We, however, have another means for measuring color effect which just in this emergency seems providential. It is a fact well known to every boy that if he rapidly whirls a lighted stick [Pg 19] the fire at the end produces the effect of a circle of light, which phenomenon is explained by a quality of the eye called retention of vision, by which the impression made by the point of light remains on the retina of the eye during an entire rotation. ”

“ To a short-sighted person, colours run together and intermix, outlines disappear, blues and reds and yellows become russets or browns, the lamps or candles of an illumination spread into an unmeaning glare, or dissolve into a milky way. He takes up an eye-glass, and the mist clears up; every image stands out distinct, and the rays of light fall back upon their centres. ”

“ Immediately over the pupil of the eye we find the faculty of Vision or sense of Sight, marked Light, which runs into a sense of Shade at the inner angle of the eye, by which two perceptions everything in nature except colors is recognized. Light extends up into Color. ”

“ As may be seen from Fig. 21, an exceedingly slight angle of motion on the part of the magnet (a) is thus made to magnify the movement of the spot of light upon the scale (f) , and to render it so considerable as to be readily noted by the eye of the operating clerk. ”

“ Or if we compare the universe accessible to sight with that accessible to sound—the plight of the blind in contrast to that of the deaf—there is the same discrepancy; the field of the eye is immensely richer, more various and more interesting than that of the ear. ”

“ WE are all agreed in preferring the light of day to any other. In spite of the extreme variations which take place in its intensity and sometimes in its coloring, we seldom think of modifying it or softening it for healthy eyes except when they are exposed to entirely unaccustomed conditions. The eye is capable of accommodating itself to most astonishing changes in the brightness of light. ”

“ Surely, then, when the sight is subsumed under the category of colour—as it unquestionably is whenever we think of the eye—surely all other colours must, of necessity, assume a position external to it; and what more is wanting to constitute that real objective universe of light and glory in which our hearts rejoice? ”

“ It is not merely the outward mechanism and motion of the eyelids, nor the colour of the eyes, that constitutes their beauty; we have already said that the leading characteristic of the eye was expression. It is this expression which causes the eye to appear to speak, to fire up suddenly, to sparkle with flashes of light, to languish or conceal itself underneath its lashes, to raise itself with inspiration, or to pierce the abyss of thought, just according to the particular sentiment governing the mind at the moment. ”

“ A visual image is modified not only by other sensations just previously experienced, but also by all those experienced simultaneously with it, and especially by such as proceed from contiguous portions of the retina. This is the phenomenon of simultaneous contrast. In this, as in successive contrast, both brightness and hue are involved. A bright object appears still brighter when its surroundings are darker than itself, and darker when they are brighter than itself. ”

“ This is the only eye that sees the mighty Beauty. If the eye that adventures the vision be dimmed by vice, impure, or weak, and unable in its cowardly blenching to see the uttermost brightness, then it sees nothing even though another point to what lies plain to sight before it. ”

“ The trained eye is capable of making a comparison between two surfaces illuminated by different sources of light, and pronouncing upon their equality or otherwise in respect of brightness, apart from a certain colour difference ”

“ It is enough for our purpose to know, that, by an apparatus of great simplicity, all the light, which, from every quarter strikes on the pellucid part of the ball of the eye,—and which if it continued to pass in the same direction, would thus produce one mingled and indistinct expanse of colour,—is so refracted, as it is termed, or bent from its former direction to certain focal points, as to be distributed again on the retina, in distinct portions, agreeing with the portions which come from each separate object, so exactly, as to form on it a miniature landscape of the scenery without. ”

“ In the heads of statues, and particularly in ideal heads, the eyes are deeper set: the bulb remains more deep than is usual in nature, in which sunken eyes render the countenance austere and cunning instead of calm and joyful. In this respect, art has departed with reason from nature; for, in figures placed to be seen at a distance, if the bulb of the eye were level with the edge of the orbit, there would be no effect produced of light and shade ”

“ I carried on conversations with her in each of these three imaginary characters,—and I ask you, is this the way to shine in Society? You may say, "Wear spectacles"—but they are unbecoming. As to an eye-glass, somehow it irritates people even more than mere blindness does. Besides, it is always dropping into one's soup. ”

“ And these proportions of apparent brightness would be accurate if all the incident rays were transmitted through the glasses to the eye, or if only an insensible part of them were stopt.”
A very important fact connected with our present subject is: The brightness of a self-luminous surface does not depend upon its inclination to the line of sight. ”

“ If my eye is to discern colour, it must itself be free from all colour. The eye with which I see God is the same with which God sees me. My eye and God's eye is one eye, and one sight, and one knowledge, and one love. ”

“ The eye of the sun itself is blind; and for ever, while it dazzles us with its light, blind it must remain. Nay, what need has it for sight at all, if in blindness it be able to fulfil its mission? And yet implicit within its vast energies, there lies the gift of sight. ”

“ Admirable as the eye undoubtedly is through the possession of the power of vision, it is also capable of enchanting us by its own particular beauties. Not to speak of its internal mechanism, which we shall consider very fully by and by, let us for a moment examine its outward appearance. Have you never, dear reader, been enchanted with a pair of soft and gentle eyes, or with a couple of black orbs veiled with long dark lashes, or with those wondrous eyes that rival the heavens in colour and depth, shedding on you rays of light whose mute eloquence was irresistible? ”

“ In the eye, for example, how wide a scene is open to us, wherever our glance maybe turned?—woods, fields, mountains, rivers, the whole atmosphere of light, and that magnificent luminary, which converts into light the whole space through which it moves, as if incapable of existing but in splendour. The mere opening of our eyelid is like the withdrawing of a veil, which before covered the universe:—It is more; it is almost like saying to the universe, which had perished, Exist again! ”

“ And all o'er heaven is that clear blue
The stars so love to wander through.
They're rising from the silent deep,
Like bright eyes opening after sleep. ”

“ Can it be possible that the eye becomes more perfect, because those who had less perfect eyes perished, and only those who could recognize colors survive until color blindness is finally eliminated? Is such a doctrine scientific? Is it more reasonable to believe it than to believe that an infinitely wise and powerful God created this organ of marvelous value and beauty? Of course, the ability to recognize color is only one of the many perfections of the eye. ”

“ But no sooner had an early twilight begun to solicit the creative faculties of the eye, than many dusky objects, with outlines imperfectly defined, began to converge the eye, and to strengthen the nascent interest of the spectator. It is true that light, in its final plenitude, is calculated to disperse all darkness. ”

“ The feature of the countenance which first strikes the observer is the eye—the "lamp of the body" as it is called in the new testament, but more fitly, perhaps, the "lamp of the soul," for in very truth the eyes are the lighted portals to man's inner nature. The most noteworthy circumstance which our data offer is the very large predominance of blue, gray and bluish-gray eyes among personages of distinction. ”

“ But, if this process be for some time continued, you will soon come to a point where doubling the actual illumination produces very little effect, and finally a stage will be reached where a very great increase of actual illumination produces no additional effect on the eye at all, your paper looking no brighter than in a much feebler light. Let me make an experiment, to at least partially illustrate this: We have now upon the screen four large squares of white light, and they are, as you see, all of equal brightness. ”

“ Of all the senses none is more frequently the seat of such deceptive judgments than that of sight; and in the science of physiological optics a very considerable share of attention is claimed by optical illusions. For the purposes of convenience, we may draw a distinction between these illusions, which are the direct result of certain properties or imperfections of the eye as an optical instrument, and those which arise from obliquities of judgment in interpreting the sensations optically impressed upon the retina of the eye. ”

“ I admit that strong lights frequently continue for some time thus visible in the ‘mind’s eye;’ and it is well known that such impressions are often followed by images of similar shape, but of various colours. In passing from sunshine to a dark room, we frequently witness the appearance of stars and circles of vari-coloured light ”
