Extract of sample

The lens provides a sharp focus on the retina, where the resulting image is upside down. From here, the light rays are turned into electrical impulses and, through the optic nerve, are sent to the brain center for optical activity.
Corneal abrasion represents a defect of the epithelial layers of the cornea. It is specifically localized in that region and does not penetrate the inner layers of the eye, such as the Bowman membrane. In some cases though, bulbar conjunctiva is also involved. It is probably one of the most common eye defects and because of its nature, in perspective with other eye defects, it is probably the most neglected. The fact that corneal abrasions heal very rapidly contributes to the fact that they are frequently missed and are considered of no consequence.
Corneal abrasions occur in every situation where there is epithelial compromise of the cornea. Such situations include certain corneal or epithelial diseases like dry eyes, superficial corneal injury or ocular injuries such as those caused by foreign objects (dust, fingernails ect.) and the use of contact lenses.
