Please explain what do you do when you get hit in the eye?

Wish you had ducked: Depends upon the type of hit. Was it a fist or softball in which case most of the energy will be absorbed by the bone. Ot was it a squash ball or flying debris like a metal fragment. Then the eye could be damaged and needs attention. If you can see well then probably you are OK. If the vision is compromised, or there is pus, or too much swelling, then see your ophthalmologist
