Brief summary

Providing Access to the Visual Environment is a pediatric low vision grant which has the ability to provide comprehensive, interdisciplinary low vision rehabilitation services to every child in Tennessee with a vision impairment. Children, ages 3-21, with best-corrected vision of 20/50 or worse in the better seeing eye are prescribed optical devices to improve their visual functioning and trained to use the devices.
