Adding several new works to his body of perceptual hacks, Olafur Eliasson’s “Your Ocular Relief” opens at Tanya Bonakdar Gallery, New York. The show’s eponymous centerpiece is an evocative light show generated by an orchestra of lenses, prisms, mirrors, and colour-effect filters carefully configured behind a curved screen. “We live in an age of the proliferation of lenses,” says Eliasson, “not only in the surveillance cameras that pepper our urban space but also in the hands of activists who are aiming them back at the instruments of power.”
