The cornea is a vital component of the human eye, functioning as a protective layer against external factors such as dust and bacteria. It is a clear, dome-shaped structure that helps to focus light onto the retina, allowing us to see clearly. There are several synonyms for the word "eye cornea," including corneal membrane, corneal surface, anterior corneal layer, and corneal epithelium. These terms are often used interchangeably when referring to the outermost layer of the eye's cornea. The cornea is an integral part of our visual system, and any damage to it can lead to vision impairment and even blindness in some cases.
