The human eye lens is made almost entirely of proteins. Nearly 60% of the entire lens is protein, which makes it the body’s most protein-rich tissue. The lens is also transparent and flexible. Its primary function is to bend light and focus it onto the retina, forming a clear image. The eye’s lens uses ciliary korean colored lenses AU muscle cells to thin and expand when focusing on a faraway object and contract when focusing on a nearby object.
The human lens is a biconvex, nearly transparent structure, composed of two layers: the crystalline and the amorphous. The crystalline layer helps refract light into a sharp image on the retina. The lenses change shape to focus on a different distance. This is called accommodation. The change in curvature allows you to shift your focus to different distances. The human lens is composed of three layers. The central layer is the most dense, while the outermost layer is the thinnest.
The ciliary body, or ciliary muscle, controls the lens’s curvature. This allows the lens to change shape and focus on objects of various distances. The zonules, or fibers that line the lens, hold the lens in place. The ciliary body also produces aqueous humor, which lubricates the lens and keeps it healthy. Aqueous humor flows through the cornea and drains from the trabecular meshwork. The aqueous fluid also helps the eye focus on near and far objects.
