Hi, I am an American Board Certified Neurologist with vast experience in diagnosing & treating all types of neurological & other medical conditions including the concerns of “New eye symptoms after accidentally shot by Nerf gun” you have mentioned here and I am very glad to help you with your health concerns.
Please see that nerf guns can rarely cause injury to the eyes
Most often they are safe but rare incidents of eye injury have been reported
It is possible the eye injury has occurred inside the eye
For example there might be some damage to a blood vessel inside the eye
Or there could be other types of damage to the eye
You need to be seen and examined by a doctor asap with these type of symptoms. You may try to visit nearest Urgent care or ER because you need an urgent eye examination and then treated appropriately so please try to visit nearest urgent care of emergency room asap.
Please not to panic, an early diagnosis and treatment can completely resolve this issue so please try to get this examined by a dr asap.
