Visionup® is the world's first vision training glasses that enhances "visual acuity (sports vision)" such as dynamic vision and peripheral vision by activating the brain and training the eye muscles. The lenses intermittently flash and block the field of vision, putting a load on the eyes and brain to perform in a situation where information is limited, aiming to improve motor skills, reflexes, and concentration. It is used not only by athletes but also for child development and maintaining visual function in the elderly, and it is said that effects can be expected by wearing it for only 10-15 minutes a day during regular practice or warm-up.
