Children with Down syndrome benefit from bifocals as evidenced by increased compliance with spectacle wear.
"....In the 27 bifocal children, all had poor accommodation on dynamic retinoscopy. ....the addition of bifocal segments improved compliance with spectacle wear in children with Down syndrome....
Comments: All children with Down syndrome should have an assessment of accommodation as a basic part of any eye examination. The majority of children with Down syndrome will require a bifocal. This study clearly shows acceptance of a multifocal design by those with this syndrome. Many other studies have demonstrated a significant accommodative problem within those who have Down syndrome, it is important to prescribe a bifocal for the majority of these individuals.
