The lens is a transparent, biconvex structure in the eye, which along with the cornea, helps refract light in order to focus on the retina. The lens, changing the shape, functions to change the focal length of the eye so that it can focus on objects at different distances, which allows you to form a clear, real image of the object of interest on the retina. This lens adjustment is called accommodation. Accommodation is like focusing on a photographic camera by moving its lenses. The lens on the front side is flatter than on the back.

The lens is also known as a aquula or a crystalline lens. In humans, the refractive power of a lens in its natural environment is about 18 diopters, which is about one third of the total power of the eye.


The lens is part of the anterior segment of the human eye. The front of the lens is the diaphragm that regulates the amount of light that enters the eye. The lens is suspended in place by a suspensory ligament of the lens, a ring of fibrous tissue that attaches to the lens at its equator and connects it to the ciliary body. The back of the lens is the vitreous body, which, along with the aqueous fluid on the front surface, emits a lens. The lens has an elliptical, biconvex shape. The front surface is less curved than the rear. In adults, the lens typically has a diameter of about 10 mm and an axial length of about 4 mm, although it is important to note that the size and shape can vary depending on accommodation and because the lens continues to grow throughout life.

A contact lens, or simply contact, is a thin lens located directly on the surface of the eye. Contact lenses are considered medical devices and can be worn for proper vision or for cosmetic or therapeutic purposes.

Contact lens holders can also wear sunglasses, eyewear, or other glasses of their choice without having to wear them with prescribed lenses or worry about glasses compatibility.
