Eye trauma: With a trauma like this, you need to see an eye doctor for further evaluation.

Need exam ASAP: This type of blunt trauma can cause numerous problems, and a dilated eye examination is indicated. The flash typically comes from traction of the vitreous gel within the eye pulling on the retina as the shock wave travels through the eye. Retinal tear, detachment, bruising, hemorrhage can result. Traumatic iritis will develop within a few days probably also (aching pain, light sensitivity).
