See-Alpha involves two major fields: muscle motion control and neuro-visual memory. Special optical devices are used to regulate and integrate eye muscle motion. After a certain period of training, a memory-based visual information processing model will be established. After a long period of training, eye muscle movement will occur in the presbyopia trainers.
