Eye Trainer - Visual Acuity Training Device The "Eye Trainer" unit While watching TV! The Eye Trainer is an innovative visual acuity training optical device conceived by Dr. Koichi Suzuki, MD, based on basic research conducted at the Department of Ophthalmology, Tokyo Medical and Dental University. Train for 15-20 minutes at a time while watching TV! Since you only need to watch your favorite TV shows or DVDs, even elementary school children can continue training without getting bored. Just look at a TV screen about 1.5 meters away, as if you were looking through binoculars. By trying to clearly see objects that change in appearance, such as enlargement/reduction, blurring, and double vision, the ciliary muscle, which adjusts the focus of the eyes, is trained. The ability to perform four eye muscle exercises simultaneously is an excellent feature, as it allows for synergistic results.
