What is the reason for dim vision in the eyes in the afternoon? The answer is: it is caused by damage to the Stomach and Brain Marrow.
Yuan Qi (Original Qi), also known as Zhen Yuan (True Origin), circulates through the Yin meridians (meridians belonging to Yin) but does not return to the Yang meridians (meridians belonging to Yang). From noon until Xu hour (7-9 PM), cold qi gradually arises, thus leading to brain damage, resulting in blurred vision at dusk. It is advisable to apply Zhenzhu Gao (Pearl Ointment) into the eyes, take Kuanzhong San (Middle-Widening Powder), Taiyang Dan (Sun Pill), Xiefei San (Lung-Draining Powder), and moxa the Fengfu acupoint.
