The cornea is the transparent front part of the eye that 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. [1] [2] In humans, the refractive power of the cornea is approximately 43 dioptres. [3]
Your cornea is the clear, dome-shaped covering at the front of each of your eyes. It’s like your eye’s version of a windshield. It keeps debris, germs and more out. Its specific shape plays a key role in how your eyesight works and filters some ultraviolet (UV) rays.
The cornea is the clear front surface of the eye. It lies directly in front of the iris and pupil, and allows light to enter the eye. The cornea has five layers.
Your cornea is your eye’s clear, protective outer layer. It acts like a barrier against dirt and germs, and it helps filter out some of the sun's damaging ultraviolet light. It also...
The clear, dome-shaped window of the front of your eye. It focuses light into your eye. Read an overview of general eye anatomy to learn how the parts of the eye work together .
The cornea is the clear outer layer at the front of the eye. There are several common conditions that affect the cornea. Read about the types of corneal conditions, whether you are at risk for them, how they are diagnosed and treated, and what the latest research says.
Light is focused into the eye through the clear, dome-shaped front portion of the eye called the cornea. Behind the cornea is a fluid-filled space called the anterior chamber. The fluid is called aqueous humor. The eye is always producing aqueous humor.
The cornea is the clear dome of tissue at the front of the eye. It connects smoothly to the sclera (the white part of the eye). The cornea refracts light through the lens below it, which allows the eye to process images.
The cornea is the transparent part of the eye that covers the front portion of the eye. It covers the pupil (the opening at the center of the eye), iris (the colored part of the eye), and...
The cornea consists of five layers: the corneal epithelium, anterior limiting lamina (Bowman’s layer), substantia propria (stroma), posterior limiting lamina (Descemet’s membrane) and endothelium, arranged anteroposteriorly. The main function of the outer coat is to protect structures inside the eye.
