A frame assembly, for wearing on the head of a person, includes left and right eye plates, each having an optical aperture and a liquid aperture. A temple includes a first post defining a first extremity and a second post defining a second extremity. The temple is subject to compression force such that a distance E between the first and second extremities is less that a distance S between holes on the frame front. The temple is resilient such that, after compression ceases, the distance E is greater than the distance S, thereby enabling the temple to be removably attachable to the frame front, without using a tool.
