The clear front window of the eye, which transmits and focuses light into the eye. The cornea is more than a protective film; it is a fairly complex structure that has five layers.

The transparent part of the eye that covers the iris and the pupil and allows light to enter the inside.

late 14c., from Medieval Latin cornea tela "horny web or sheath," from Latin cornu (genitive cornus) "horn," from PIE *ker- (1) "horn; head, uppermost part of the body" ( [..]

transparent anterior part of the external coat of the eye covering the iris and the pupil and continuous with the sclera.

The transparent part of the eyeball that covers the iris and pupil. It refracts light entering the eye on to the lens, which is then focused on to the retina.

The outer transparent coat of the eye. corneum

noun. The see-thru area of the outer lining of the eye ball, through which light initially passes.

cornea (pop)

The cornea is the transparent outer layer of the eye responsible for protection and vision. It protects the inner parts of the eye from germs and small objects like dust along with the filtration of h [..]

The transparent front part of the eye that covers the iris, pupil, and anterior chamber, providing most of an eye’s optical power

(KOR-nee-uh). Transparent front part of the eye that covers the iris, pupil, and anterior chamber and provides most of an eye's optical power.

The transparent outer layer of the eye, whose curvature is fixed. It bends light rays and is primarily responsible for forming the image on the retina. See Figure 10.1.

The surface of the eye that accomplishes the initial focusing of light. The cornea is transparent to visible and near-infrared radiation, but absorbs both ultra-violet and infrared light. Damage to th [..]

(n) the transparent dome-shaped anterior portion of the outer covering of the eye; it covers the iris and pupil and is continuous with the sclera

The outer, transparent, dome-like structure that covers the iris, pupil, and anterior chamber. The cornea provides approximately two-thirds of the optical power of the eye. Light passes into the eye through the cornea allowing vision. Light also passes out of the eye allowing the iris and pupil of the eye to be seen. The cornea can b [..]

The clear dome that covers the front of the eye.

(L. corneus =horny) The transparent front window of the eye. Light passes into the eye allowing vision and also out of the eye allowing the iris and pupil of the eye to be seen. The corn [..]

The transparent covering of the front of the eye (19thc)

It's part of your eye, but you've probably never noticed it before. The cornea is thin, clear and covers your eye. It's important because it helps you see by focusing light as it enters [..]

The cornea allows light to enter the eye, and is the transparent region of the modified sclera. It is part of both the tunica fibrosa as well as the optical components of the eye.

the transparent covering of the front of the eye that transmits and focuses light into the eye.

The transparent anterior portion of the fibrous coat of the eye consisting of five layers: stratified squamous Corneal Epithelium; Bowman Membrane; Corneal Stroma; Descemet Membrane; and mesenchymal C [..]

The transparent anterior portion of the fibrous coat of the eye consisting of five layers: stratified squamous CORNEAL EPITHELIUM; BOWMAN MEMBRANE; CORNEAL STROMA; DESCEMET MEMBRANE; and mesenchymal C [..]

The transparent outer part of the eye that covers the iris and pupil and admits light into the eyeball.

 A thin, curved transparent membrane on the surface of the front of the eye. It begins the focusing process for vision. 

the outer, transparent surface of the compound eye.

   The clear covering of the eye.

The transparent part of the eye that covers the iris and the pupil and allows light to enter the inside.

the transparent outer covering of the eyeball

The clear, transparent anterior portion of the fibrous coat of the eye comprising about one sixth of its surface; composed of five layers.

the clear window at the front of the eye.

The clear, dome-shaped surface that covers the front of the eye.

The outer curved transparent tissue covering the iris and pupils on the outside of the eye. Only the cornea is removed for corneal transplants.

The clear tissue covering the front surface of the eye that permits light to enter and provides most of the focusing power.

The thin transparent membrane in the front part of the eye: it protects the inner tissues of the eye.

(anatomy) The transparent layer making up the outermost front part of the eye, covering the iris, pupil, and anterior chamber.

The clear "watch crystal" structure covering the pupil and iris (colored portion of the eye). It is composed of several vital layers, all of which are functionally important. The surface lay [..]
