The invention provides a design method of an anti-reflection microstructure of a curved surface guidance window. The design method comprises the following steps: step 1, modeling the curved surface of the guidance window, equally dividing a central angle, and simulating to obtain the transmittance of each plane; 2, exporting the group of plane transmittances, and calculating to obtain the corresponding curved surface transmittances; 3, further reducing the angle interval, and repeating the step 1 and the step 2 to obtain the transmittance of the next group of curved surfaces; 4, comparing the front and rear groups of curved surface transmissivity data, judging whether the error is smaller than a preset value or not, and determining the transmissivity of the guidance window until the error between the front and rear groups of curved surface transmissivity is reduced to be smaller than the preset value; and 5, confirming the design scheme of the microstructure when the design requirement of the guidance window
