In most people’s eyes, there are more or less Demodex (that is, aphids often mentioned). “When the number of parasites is small and the immune function of the body is normal, Demodex does not cause blepharitis. But when the number of Demodex When it is significantly increased and the body’s immune function is dysfunctional, Demodex can become a pathogenic pathogen, causing disease.”
The reason why the morning symptoms are more obvious is that Demodex tends to be active at night. In the evening, it crawls in and out of the hair follicles, which is prone to produce more bacteria and secretions, and also causes a large increase in eyelids.
