1. Allergic Reactions: Allergies to environmental allergens like pollen, dust, or food can cause swelling and inflammation around the eyes.

3. Conjunctivitis (Pink Eye): Conjunctivitis is an inflammation of the conjunctiva, a membrane that lines the eyelid and covers the white part of the eye. It can be caused by bacterial or viral infections, allergies, or irritants.
4. Corneal Ulcers: Corneal ulcers are injuries to the cornea, the transparent outer layer of the eye. They can be caused by scratches, punctures, or other trauma to the eye.
5. Glaucoma: Glaucoma is a condition in which the pressure within the eye increases, leading to damage to the optic nerve and potential blindness.
6. Uveitis: Uveitis is an inflammation of the uvea, the middle layer of the eye. It can be caused by infections, autoimmune diseases, or injuries.
7. Stye (Hordeolum): A stye is a bacterial infection of the oil glands in the eyelid, causing a red, swollen, and painful bump to develop on the eyelid.
