The cornea helps to focus light that comes into your eye onto the retina. Its nerves alert you to irritations that might harm your vision and eye health. It does not have blood vessels to give it nourishment. Rather, it gets the majority of its nourishment from the tears on the surface and the aqueous humor from inside your eye. The cornea has five layers. If an injury breaks through to a deeper layer, healing can take longer and may lead to blurred vision, sensitivity to light, pain, and tearing. A more serious injury will lead to corneal scarring.

Dry eyes can develop because of allergies, skin disease, contact lenses, certain medications, and chemical or tobacco smoke exposure. Also, people who are more than 65 years old are at risk of dry eye.
