I am 31 year old. A few hours back my 6 year old niece threw a plastic toy at my face while playing which directly hit my eye. As soon as it hit my eye i lost vision for a few seconds making my vision blue. Following I had a headache and eye started twitching for a while and a little portion of the white of my eye turned red. Is it normal to lose vision for a few seconds when something hard hits the eye suddenly? Are the above mentioned symptoms typical of sudden blow to the eye? Should i be concerned or will it resolve over time? Please explain
