cornea
Sign in to saveThe cornea is the transparent front part of the eye which covers the iris, pupil, and anterior chamber. Along with the anterior chamber and lens, the cornea refracts light, accounting for approximately two-thirds of the eye's total optical power. In humans, the refractive power of the cornea is approximately 43 dioptres. The cornea can be reshaped by surgical procedures such as LASIK.
AI overview
The cornea is the clear front layer of your eye that sits over the colored part (iris) and pupil, and it works together with other eye structures to bend light so you can see clearly. It does most of the heavy lifting for your eye's focusing power—about two-thirds of it—which is why keeping it healthy is important for good vision.

The cornea is the transparent front part of the eye which covers the iris, pupil, and anterior chamber. Along with the anterior chamber and lens, the cornea refracts light, accounting for approximately two-thirds of the eye's total optical power. In humans, the refractive power of the cornea is approximately 43 dioptres. The cornea can be reshaped by surgical procedures such as LASIK.
While the cornea contributes most of the eye's focusing power, its focus is fixed. Accommodation (the refocusing of light to better view near objects) is accomplished by changing the geometry of the lens. Medical terms related to the cornea often start with the prefix "kerat-" from the Greek word κέρας, horn.
