What to do if i was hit in the eye with a foam (with plastic around it) dodgeball?

See eye doctor: If you were hit in the eye, you should see an eye doctor for evaluation, especially if you have symptoms such as pain, redness, blurred vision or floaters.

See urgent care doc: A blow to the eye by any projectile, blunt or sharp required an examination. You never know what concerns there are without a thorough exam. This is especially true for penetrating injuries. But even blunt injuries can result in inflammation, bleeding and torn tissues, all of which can affect your vision. See an Eye MD or urgent care MD ASAP.
