Eyesore (逃避眼神)

According to Wikipedia, the lens, also known as the crystalline lens, is a biconvex transparent tissue held in place by ligaments behind the iris and in front of the vitreous body. The lens is an important component of the eye's refractive system and the only refractive medium with the ability to adjust focus—in other words, the function that lets our eyes see near and far, this place and that.

A once-familiar place, where something seems to have happened: under the National Security Law, people can only avert their gaze from one another—they see, yet cannot see.
