Tcm confinement myths

In TCM practice, It is believed that you cannot read or cry or use handphone in the dark room during confinement, as childbirth is thought to weaken the liver, and the liver is associated with blood, which is associated with the eyes. So you must avoid stress to the eye otherwise it will cause 青光眼 (glaucoma) Instead you must consume more wolfberry to strengthen the eye as wolfberry strengthen the liver. Is there truth to these 3 questions? Namely is liver connected to the eye? Does reading, crying, using handphone weaken the eye? and does wolfberry help protect the eyes?
