These special charts combine several therapy procedures including near-far accommodation, vergence training, anti-suppression and visual acuity skills. The two red-block letter charts create a binocular environment to improve accommodation and saccadic eye movement skills. The two charts can be used together to train near-far ductions. There are different suppression checks for each chart, thus allowing treatment of bilateral amblyopia cases. Includes the LC1 and LC2 letter Charts and 1 pair disposable red/clear glasses.
