The binocular alternate occlusion method can be used for refractive amblyopia and monocular strabismic amblyopia. If the vision of the amblyopic eyes is equal, binocular equal quantity alternate occlusion can be adopted, with each eye covered for 3 days; if there is a difference in vision between the eyes, a 4:1 or 5:1 method can be used according to the specific situation, meaning covering the better-seeing eye for 4 days and then switching to cover the weaker-seeing eye for 1 day, allowing the eye with poorer vision to see more things, thereby training it more and promoting faster improvement in vision, aiming for balanced and enhanced binocular vision.
