David Osorio, 21, an English teacher and a student, who was injured during a protest against Venezuela's President Nicolas Maduro's government, poses for a photograph inside his home in Caracas, Venezuela, August 15, 2017. Osorio said he was struck by a tear gas canister on July 7, 2017, fracturing his skull and leaving him blind in his right eye. He uses a temporary prosthetic eye while seeking specialist treatment. "I have been protesting since 2014. During the last few months, I was actively participating in all the marches, because things have gotten worse and I am against the policies of this government."
