Eyepiece

“ Suppose that a pencil is held in front of the eye at the distance at which we see small objects comfortably. Light is reflected from all parts of the surface of the pencil, and as the rays spread, a certain number enter the pupil of the eye. We will follow only two cones of light coming from the points 1 and 2 on the diagram Fig. 11. These you see enter the eye, each widely spread over the cornea c. They are bent in a little by this curved covering, and by the liquid behind it, while the iris cuts off the rays near the edges of the lens, which would be too much bent to form a clear image. ”

“ And what an expression about the eyes!"
"The eyes are unequalled in any modern statue," said the Doctor. "You observe that they are set in rims of bronze, which serve for eyelids; the eye itself is made of opaque quartz, like ground glass, and there is a piece of rock-crystal in the centre, which forms the pupil. If you look closely you see a glittering point below the crystal, which makes the eye sparkle as though its owner were about to smile. There is nothing of modern times that equals it." ”

“ Persons whose sight is beginning to fail at the near-point, or who are approaching the presbyopic age, should imitate the example of this remarkable old gentleman. Get a specimen of diamond type, and rend it every day in an artificial light, bringing it closer and closer to the eye till it can be read at six inches or less. ”

“ I want to talk to you about your eyes, and I hope that you will be able to understand that they are worth hundreds and thousands, yes millions of dollars to each of you. In order that I may better illustrate a few of the many wonderful things about the human eye, I have brought this field-glass, and here is a small spy-glass, and also a magnifying lens, or sun-glass, as boys sometimes call them. ”

“ Watch-glasses, which perfectly retain their transparency, have resisted every attempt to break them by crushing between the fingers, or by throwing them about indiscriminately on the bare floor. Glass plates, dishes, colored lantern-glasses, and the like, have been similarly thrown about by the handful, stood upon, and otherwise maltreated, but without the slightest injury accruing to them, except, perhaps, when a solitary specimen which had been imperfectly tempered got in with the rest. ”

“ Both the object-glass and the eye-piece may, and usually do, consist of more than one lens, for, as previously mentioned, better results are obtained by a combination of lenses of moderate power than by single lenses of high power and great curvature. ”

“ To supply this great defect, the eye is a multiplying glass, with a lens looking in every direction, and showing every object that may be near. Thus, what seemed at first a privation, by this curious and interesting expedient is made to be an advantage, as an eye thus constructed, seems better adapted to the wants of these creatures than any other. ”

“ There is no place going which is so well adapted to the exhibition of handsome, fashionable, or eccentric eye-glasses as an art exhibition. You observe there all that is newest and classy in glasses, and you are insistently invited to admiring study of the art of wearing queer glasses effectively, and of taking them off, letting them bound on their leash, doubling them up, opening them out, and putting them on with a gesture.
The complimentary type to the storied Duchess at art exhibitions is represented by yonder portly blood, in this case a replica of the late King Edward. ”

“ A dull or colorless complexion can be brightened with multicolored earclips and necklaces. The colors of the precious stones will reflect and shed their glow upon the skin. Bold colors will lend their drama to the face.
On eyeglasses, all color should be shunned. Rhinestone-studded or multicolored frames call attention to themselves. The purpose of eyeglasses is purely functional; they should be left unobtrusive, not made competitors of the clip. ”

“ Then, after eyeglasses are put on, they must be changed now and then to suit the changing conditions of the sight. If the eyes are not in a bad state, wearing spectacles for a few months may strengthen them so that the glasses can be discarded. ”

“ In carefully-made and expensive instruments compound lenses are used, which by the employment of different kinds of glass bring all the colours to practically the same focus, and so do away with chromatic aberration. ”

“ A woman who wears eyeglasses will be pleasantly surprised if, for more formal occasions, she tries the effects of the lorgnon or lorgnette. Whereas eyeglasses, fixed upon the face, tend to fight with the features or with other accessories, the lifted lorgnette becomes not only an adornment but a weapon. ”

“ To find which is the master eye, hold a pencil out at arm’s length and point it at some small distant object with both eyes open, then close the left eye, and if the pencil still points to the object, the right eye controls the vision, and is the master eye. ”

“ I know nothing, indeed, which so disfigures the countenance of a young person, or so impresses every feature with an air of demureness, if not altogether of sanctimoniousness and of age. An eyeglass, on the other hand, has a savor of downright foppery and affectation. ”

“ He carried a gold-rimmed double eyeglass, which he constantly rubbed, during which process his grey short-sighted eyes would travel steadily round, seeing nothing but the subject which occupied his mind, helping to put the barrier of a stately reticence between him and his client. ”

“ If, after reading a short time, your eyes begin to trouble you, why not have this ailment relieved, by properly fitted glasses? We have an expert optician, and do our own grinding. Satisfaction guaranteed. ”

“ Glazed transparent linen is placed over the engraved lines, and through this, with ink and stencil, the most intricate and exquisite lines are drawn. To do this work perfectly, a lady must be something of an artist and draughtswoman. Magnifying glasses are used, and even with their aid, the work is most trying, and often destructive to the eyesight. ”

“ We had a great show-case full of glittering paste—bracelets, tiaras, coronets, sunbursts, dog-collars, rings, necklaces—all extremely modish, and so handsome that they would have deceived any but trained eyes. ”

“ Indeed, the effect is just such as would have been produced if the artist had worked in wax. Again, in the modeling of the eyes we have a good illustration. The eye is a minute ball cleft across the entire diameter by a sharp implement, thus giving the effect of the parted lids. ”

“ The hues of the opal, the light of the diamond, are not to be seen, if the eye is too near. ”

“ Certainly they should not gleam with gold nor glitter with rhinestones when one is wearing earclips. The meretricious sparkle of the eyeglass rims draws attention from the earclips—which is the reverse of the proper procedure, for well designed clips can lure attention away from the glasses. ”

“ Neglecting details which are immaterial for our present purpose, we may regard the uncut pencils as representing upon an enormously magnified scale the rods of the retina, and the pointed ones the cones. ”

“ The eye—which sees all objects reversed—retains the images for some time. This conclusion is proved by the results; because, the eye having gazed at light retains some impression of it. After looking (at it) there remain in the eye images of intense brightness, that make any less brilliant spot seem dark until the eye has lost the last trace of the impression of the stronger light. ”

“ The tip no jewel needs to wear;
The tip is jewel of the ear. ”

“ The eye is continually influenced by what it cannot detect; nay, it is not going too far to say, that it is most influenced by what it detects least. Let the painter define, if he can, the variations of lines on which depend the changes of expression in the human countenance. ”

“ For the eye is always in search of beauty, and if we do not gratify its desire for pleasure by a proportionate enlargement in these measures, and thus make compensation for ocular deception, a clumsy and awkward appearance will be presented to the beholder. ”

“ The eye which turns from a white object in the light of the sun and goes into a less fully lighted place will see everything as dark. ”

“ Every woman, even the most respectable, had roses blooming under glass; lips cut with a knife; curls of Indian ink; there was design, art, everywhere; a change of some sort had undoubtedly taken place. ”

“ And the eye can best distinguish the forms of objects when it is placed between the shaded and the illuminated parts. ”

“ And I have known the arms already, known them all—
Arms that are braceleted and white and bare
(But in the lamplight, downed with light brown hair!)
Is it perfume from a dress
That makes me so digress?
Arms that lie along a table, or wrap about a shawl.
⁠And should I then presume?
⁠And how should I begin? ”

“ I sometimes wonder if the hand is not more sensitive to the beauties of sculpture than the eye. I should think the wonderful rhythmical flow of lines and curves could be more subtly felt than seen. Be this as it may, I know that I can feel the heart-throbs of the ancient Greeks in their marble gods and goddesses. ”

“ One face looks out from all his canvases,
One selfsame figure sits or walks or leans:
We found her hidden just behind those screens,
That mirror gave back all her loveliness.
A queen in opal or in ruby dress,
A nameless girl in freshest summer-greens,
A saint, an angel – every canvas means
The same one meaning, neither more nor less.
He feeds upon her face by day and night,
And she with true kind eyes looks back on him,
Fair as the moon and joyful as the light:
Not wan with waiting, not with sorrow dim;
Not as she is, but was when hope shone bright;
Not as she is, but as she fills his dream. ”

“ I GIVE THE DEGREES OF THE OBJECTS SEEN BY THE EYE AS THE MUSICIAN DOES THE NOTES HEARD BY THE EAR. Although the objects seen by the eye do, in fact, touch each other as they recede, I will nevertheless found my rule on spaces of 20 braccia each; ”

“ I think it was his eye! yes, it was this! One of his eyes resembled that of a vulture—a pale blue eye, with a film over it. Whenever it fell upon me, my blood ran cold; and so by degrees—very gradually—I made up my mind to take the life of the old man, and thus rid myself of the eye for ever. ”

“ The noblest feature, the eye, is the fairest-colored, the jewel of the body. ”

“ It is impossible that the eye should project from itself, by visual rays, the visual virtue, since, as soon as it opens, that front portion [of the eye] which would give rise to this emanation would have to go forth to the object and this it could not do without time. And this being so, it could not travel so high as the sun in a month's time when the eye wanted to see it. ”

“ It was long before they moved, and when they moved it was with great reluctance. They stood together in front of the looking-glass, and with a brush tried to make themselves look as if they had been feeling nothing all the morning, neither pain nor happiness. But it chilled them to see themselves in the glass, for instead of being vast and indivisible they were really very small and separate, the size of the glass leaving a large space for the reflection of other things. ”

“ He was so very neat and so very clean-shaved, and he always wore an eye-glass in his right eye. It seemed to grow there, for it had no string, and he never took it out except to wipe it. At first I thought he used to sleep in it, but afterwards I found that this was a mistake. He put it in his trousers pocket when he went to bed, together with his false teeth, of which he had two beautiful sets that, my own being none of the best, have often caused me to break the tenth commandment. ”

“ THE BODY WHICH IS NEAREST TO THE LIGHT CASTS THE LARGEST SHADOW, AND WHY? If an object placed in front of a single light is very close to it you will see that it casts a very large shadow on the opposite wall, and the farther you remove the object from the light the smaller will the image of the shadow become. ”

“ The outlines and form of any part of a body in light and shade are indistinct in the shadows and in the high lights; but in the portions between the light and the shadows they are highly conspicuous. ”

“ Had I the heavens' embroidered cloths,
Enwrought with golden and silver light,
The blue and the dim and the dark cloths
Of night and light and the half-light,
I would spread the cloths under your feet:
But I, being poor, have only my dreams;
I have spread my dreams under your feet;
Tread softly because you tread on my dreams. ”

“ They were wider than a man's hand with his fingers spread and the fish's eye looked as detached as the mirrors in a periscope or as a saint in a procession. ”

“ I have always had more dread of a pen, a bottle of ink, and a sheet of paper, than of a sword or pistol.” ”

“ Lovely eyes in colour, lovely eyes in form—large and tender and quietly thoughtful—but beautiful above all things in the clear truthfulness of look that dwells in their inmost depths, and shines through all their changes of expression with the light of a purer and a better world. ”

“ What furniture can give such finish to a room as a tender woman's face?—and is there any harmony of tints that has such stirrings of delight as the sweet modulation of her voice? ”

“ millions of millions of vibrations have penetrated the eye before the eye can distinguish the tints of a violet. ”

“ One morning I fell to sketching a face: what sort of a face it was to be I did not care or know. I took a soft black pencil, gave it a broad point, and worked away. Soon I had traced on the paper a broad and prominent forehead, and a square lower outline of visage: that contour gave me pleasure; my fingers proceeded actively to fill it with features. Strongly marked horizontal eyebrows must be traced under that brow; then followed, naturally, a well-defined nose, with a straight ridge and full nostrils; then a flexible-looking mouth, by no means narrow; ”
