تعريف lens في الإنجليزية الإنجليزية القاموس.: To become thinner towards the edges; A genus of the legume family; its bean; A way of looking, literally or figuratively, at something
If the public looks at the condition of America's children largely through a negative lens, worries Child Trends , it may be more difficult to promote child well-being..; The transparent crystalline structure in the eye; An object, usually made of glass, that focuses or defocuses the light that passes through it; A convex shape bounded by two circular arcs, joined at their endpoints, the corresponding concave shape being a lune; A device which focuses or defocuses electron beams; To film, shoot; {n} a glass which diverts the rays of light form a direct course; A lens is a thin curved piece of glass or plastic used in things such as cameras, telescopes, and pairs of glasses. You look through a lens in order to make things look larger, smaller, or clearer. a camera lens I packed your sunglasses with the green lenses; The transparent, crystalline, flexible structure in the front of the eye directly behind the pupil Tiny muscles change the shape of the lens to bend the entering light, helping the eye focus for seeing up close and far away; A transparent double convex (outward curve on both sides) structure between the iris and the vitreous humor Two structures of the eye focus light onto the retina The first is the cornea or front surface of the eye that provides about 65% of the focusing power of the eye The human lens is located behind the iris and in front of the vitreous humor and provides the remaining focusing power for the eye In younger patients (usually below age 45) the lens is able to adjust it's power allowing the eye to change it's focal length from distance to near; A piece of glass, or other transparent substance, ground with two opposite regular surfaces, either both curved, or one curved and the other plane, and commonly used, either singly or combined, in optical instruments, for changing the direction of rays of light, and thus magnifying objects, or otherwise modifying vision; is a part of the eye that provides some focusing power The lens is able to change shape allowing the eye to focus at different distances; a transparent optical device used to converge or diverge transmitted light and to form images; The part of the eye behind the iris that adjusts focus for different distances by changing shape; {i} piece of transparent material having two opposite surfaces which refract rays of light to form an image; part of the eye which focuses light rays to form an image on the retina; The transparent structure in the front of the eye With outward curves on both sides, the lens helps focus light on the retina A piece of glass or other transparent material having two polished opposite surfaces, at least one of which is curved; One or more pieces of optical glass used to gather and focus light rays to form an image; In practice, the curved surfaces are usually spherical, though rarely cylindrical, or of some other figure; In your eye, the lens is the part behind the pupil that focuses light and helps you to see clearly. see also contact lens, telephoto lens, wide-angle lens, zoom lens. Piece of glass or other transparent substance that is used to form an image of an object by converging or diverging rays of light from the object. Because of the curvature of its surface, different rays of light are refracted (see refraction) through different angles. A convex lens causes rays to converge on a single point, the focal point. A concave lens causes rays to diverge as though they are coming from a focal point. Both types cause the rays to form a visual image of the object. The image may be real inverted and photographable or visible on a screen or it may be virtual erect and visible only by looking through the lens; The glass or plastic element through which light first enters your camera If you have a poor-quality lens, it doesn't matter how many megapixels or other features a camera has, the picture will be poor Plastic lenses can make your photo look as though they were taken on a foggy day Aspherical glass lenses produce better pictures by reducing the slight distortion often caused by circular lenses; To film; Transparent biconvex tissue within the eye that helps bring rays of light to focus on the retina The lens crystalline can change shape and increase the optical power of the eye when viewing near objects This ability to accommodate is lost after age 40, requiring the use of bifocals or reading glasses; electronic equipment that uses a magnetic or electric field in order to focus a beam of electrons; the transparent, dual-convex body which focuses light rays onto the retina (See "Anatomy of the Eye" on the MD Support web site ); The lens sits in the middle of the eye, behind the pupil It focuses the light onto the retina so that you see clear images The lens is a remarkable instrument that adjusts from reading fine print to reading a movie marquee 100 or more feet away Tiny ligaments keep the lens suspended in place (Marks 3); (metaphor) a channel through which something can be seen or understood; "the writer is the lens through which history can be seen"; A structure inside the eye that helps to focus light on the retina It is curved on both sides and acts similar to a camera lens; A cylinder of shaped pieces of glass or plastic at the front of a camera, the lens projects a tiny image of the subject onto the film; a part of the eye that provides some focusing power The lens is able to change shape allowing the eye to focus at different distances; One or more pieces of optical glass or similar material designed to collect and focus rays of light to form a sharp image on the film, paper, or projection screen; The crystalline lens of the eye is located behind the pupil and iris of the eye and its job is to flex and bend to help focus the light coming in The lens relaxes and contracts when focused at near and far distances to apply more or less "zoom" power in order to see object clearly This structure is generally quite clear and cannot be seen without special equipment If it gets cloudy, we refer to this as a "cataract " SEE: ACCOMMODATION; A combination of shaped glasses and air spaces set in a specific arrangement within a barrel Within the lens is a diaphragm that can be opened and closed to allow in specific amounts of light This is controlled manually by a ring on the outside of the lens barrel, or electronically via pins in the coupling ring that mounts the lens to the camera Lenses have two primary functions: one is to focus light with as little distortion or aberration as possible on to film or sensor Focusing is accomplished by changing the relationship of the elements in the lens to the film plane The other function is to control the amount of light hitting the film by use of its aperture Autofocusing lenses may contain small motors for racking the lens back and forth in response to changes in focus; the transparent structure inside the eye that focuses light rays onto the retina; a transparent optical device used to converge or diverge transmitted light and to form images electronic equipment that uses a magnetic or electric field in order to focus a beam of electrons biconvex transparent body situated behind the iris in the eye; it focuses light waves on the retina (metaphor) a channel through which something can be seen or understood; "the writer is the lens through which history can be seen"; (also called crystalline lens) - the transparent structure inside the eye that focuses light rays onto the retina; biconvex transparent body situated behind the iris in the eye; it focuses light waves on the retina; A transparent, biconvex, nearly spherical body in the eye which focuses light passing through the pupil (images) onto the retina; genus of small erect or climbing herbs with pinnate leaves and small inconspicuous white flowers and small flattened pods: lentils; An optical device made of glass or other transparent material that forms images by bending and focusing rays of light A lens made of a single piece of glass cannot produce very sharp or exact images, so camera lenses are made up of a number of glass "elements" that cancel out each other's weaknesses and work together to give a sharp true image The size, curvature and positioning of the elements determine the focal length and angle of view of a lens; a transparent optical element, so constructed that it serves to change the degree of convergence or divergence of the transmitted rays; A lens is a clear object which changes the direction of light beams passing through it There is a part of the eyeball called the lens, which focuses light on the retina Corrective lenses, such as contact lenses and eyeglass lenses, change the direction of incoming light so that a clear image appears on the retina and you can see clearly; The crystalline lens finishes the focusing of light It helps to "fine tune" vision, and it is able to change shape to allow the eye to focus on near objects When it becomes cloudy, it is called a cataract Unlike the cornea, the lens can be made to change its shape (and, therefore, its refractive power) rapidly and voluntarily Using its ability to change shape, the lens allows the eye to change its focal point Changes in the shape of the lens will allow a normal eye to focus on near objects; A structure made of transparent glass or other material, with at least one curved surface, which causes the light rays passing through it to converge or diverge in a controlled fashion; A medium which will bend light The eye has its own crystalline lens that helps focus light Spectacle lenses help bend the light in such a way that once it reaches the eye it can then be focused Contact lenses do the same except that they are in contact with the eyeball
