Abstract: A tear collection device comprises: a body attached to an eyeball; a tear inlet for allowing tear to flow into the body; a storing space formed inside the body and capable of storing the tears having flowed into the body; and a pump forming a pressure difference inside the body such that tears flow into the body through the tear inlet, wherein the pump is driven by using, as power, eye blinking movements of a wearer so as to form the pressure difference inside the body, thereby allowing the tears to flow into the body.
