Lens

The Lens is a transparent crystalline formation that is located behind the pupil of the eye and is surrounded by a thin transparent shell called a capsule. The lens is one of the refractive media of the eye and plays an important role in focusing rays penetrating the eye on the surface of the retina.

The lens is shaped like a biconvex lens and consists of transparent protein fibers that are organized into concentric layers. In the center of the lens there is a core, which consists of denser fibers than the peripheral layers. This provides higher refractive power at the center of the lens, allowing the eye to focus images at different distances.

The function of the lens is related to the process of accommodation, which allows the eye to change the shape of the lens to focus images at near and far distances. When we look at a close object, we tense the muscles of the ciliary body, which compress the lens and make it more convex. This increases the refractive power of the lens and allows the eye to focus the image on a close object. When we look at a distant object, we relax the muscles of the ciliary body, which allows the lens to return to its flatter shape and focus the image on the distant object.

The lens is an important element of the visual system and its function plays a key role in the eye's ability to adapt to different lighting conditions and object distances. Lens disorders such as cataracts can reduce the quality of vision and require treatment. Taking care of your eyes and eating right can help keep your lens and visual system healthy.

The lens or Lens is a transparent crystal formation that is located behind the pupil in the eye. It helps focus light rays passing through the eye onto the surface of the retina to form images, which is necessary for normal vision.

The lens is one of the four refractive media of the eye - the other three: aqueous humor, vitreous humor
