Fifty cases of cured amblyopia were examined in relation to distance vision, near vision, and reading capacity. Occlusion had been abandoned at age 8; the examination was made at age 12. Although linear vision for distance and near was full, reading capacity was markedly impaired. In order to prevent this 'reading amblyopia', sneaking-out or tapering-off occlusion with alternating calibrated filters is continued until the child can read fluently with each eye.
