If the itching in the eyes is extremely unbearable, it is due to Heat pathogen invading the Liver Meridian (Liver Channel), and Gallbladder deficiency-Heat. Wind Pathogen attacks and fills the area. The Liver contains extreme Heat; when the Liver is affected by the drying and moving nature of Wind, similar to trees shaking with the wind, itching arises. Therefore, all itching belongs to Deficiency (Xu); Deficiency causes itching. All pain belongs to Excess (Shi); Excess causes pain. Some have itching of the black pearl (cornea), some have itching of the eyelid margins. These can be treated with point application of Dan Yao (mineral/alchemical pills), or friction with roasted ginger. When tears flow, the itching stops.
