I though it was gana be bad I freaked out and went to the optometrist and they said its perfectly normal, it can happen caughing sneezing or over exerting on the toilet or lifting, I had never seen it before basically all the white in one eye was red, but they did say it can be bad if the blood moves into the color part of ur eye or pupil. Some freaks at my gym seen an after I told them how I did it they were like hell yea ! Lol but eye fully recovered after 3-4 weeks, only told put eye drops in if bothered me. My first day. back at work after they wanted to send me home I had to give them a dr note. It looked pretty crazy.
