Cornea and external eye diseases

The cornea is the outer layer covering the front of the eye which acts as a barrier to protect the eye from foreign objects, helps with vision by focusing light, and filters ultraviolet rays that enter the eye. The cornea can usually heal itself after scratches or some minor injuries but sometimes the cornea and other external eye structures require medical treatment for more serious injuries such as allergies, inflammation, infections, corneal dystrophies, and a wide range of other conditions. The cornea is the reasonable tissue at the upfront of the eye. Its straight reflection allows light to go into the eye, through the understudy and then to the retina at the back of the eye. The three corneal layers are the external layers of the cornea or epithelial layer, the centre layer named the stroma, a solitary layer of cells called the endothelium. The ebb and flow of the cornea assumes an essential part in centering light. The typical cornea is smooth, clear, and extreme. It shields the eye from contamination and outside material.
