Allergy is considered to be a multifactorial disease with no known trigger. The hypothesis of allergy: in genetically predisposed individuals, long-term negative factors (chronic stress) cause excessive pupil constriction via the cortico-nuclear pathways, which is manifested by significant activation of the parasympathetic nervous system. Constricted pupils (reduced luminous flux) trigger pathological biochemical processes in the body through the optic-vegetative system, which leads to a deterioration in the physical and psychological conditions of patients. 

It is proposed to include in the protocol for the treatment of allergies (and all somatic and mental illnesses) the medical dilation of the pupils to relieve the negative effects of an overactivated parasympathetic nervous system on the body
