Sight Training: Enjoy Exercising & Relaxing Your Eyes was developed in co-operation with Dr Hisao Ishigaki of the Aichi Institute of Technology, an expert in the field of visual training who has developed sight training programmes used by professional athletes. He identified five different aspects of visual ability. You use many kinds of visual abilities in daily life. Identifying several objects in a wide range of vision at once, correctly recognising moving objects & so on make up your ability to see. In other words, you could say your visual ability is the accuracy & agility of your eyes. In this game we call your visual ability Focus Ability, & aim to improve it through training.
