How is light that enters the eye affected by conjunctivitis?

Conjunctivitis, also known as pink eye, is an inflammation of the conjunctiva, a thin membrane that lines the eyelid and covers the white part of the eye. Conjunctivitis can be caused by a bacterial or viral infection, allergies, or irritants.

When light enters the eye, it passes through the cornea, the clear outer layer of the eye that covers the pupil and iris. The cornea helps to focus light onto the retina, the light-sensitive tissue at the back of the eye. If the conjunctiva is inflamed, it can cause the cornea to become cloudy or swollen, which can scatter light and make it difficult to see clearly.

Conjunctivitis can also cause the eyes to become red, irritated, and watery. These symptoms can make it difficult to keep the eyes open and can cause sensitivity to light. In some cases, conjunctivitis can also cause the eyelids to become crusted or stuck together.

If you are experiencing any of the symptoms of conjunctivitis, it is important to see an eye doctor to get a diagnosis and treatment.
