Air coming out of the eye is not a normal occurrence and may be a sign of a medical issue. The following are some possible causes of air coming out of the eye:

1. Subconjunctival emphysema: Subconjunctival emphysema is a condition in which air becomes trapped under the conjunctiva, the thin transparent layer that covers the white part of the eye. This can cause the eye to appear swollen and may be accompanied by discomfort or pain. Subconjunctival emphysema is often caused by trauma to the face or head, such as a blow to the nose or a sinus infection.
2. Orbital emphysema: Orbital emphysema is a condition in which air becomes trapped in the orbital cavity, the space around the eye that contains the eye and its muscles. This can cause the eye to bulge and may be accompanied by discomfort or pain. Orbital emphysema is often caused by trauma to the face or head, such as a blow to the nose or a sinus infection.
3. Orbital blowout fracture: An orbital blowout fracture is a type of fracture in which the bones surrounding the eye are broken. This can cause air to become trapped in the orbital cavity and may cause the eye to appear swollen and bulge.
