This Low Vision book with LEA NUMBERS® is designed for testing severely visually impaired children and adults. This complete book includes testing at 10 ft (3 meters), 5 ft (1.5 meters) and for near vision testing at 16" (40 cm). Distance testing line sizes range from 20/1600 to 20/16 equivalent. Near vision testing line sizes range from 20/800 to 20/16 equivalent.

The LEA NUMBERS® Low Vision book can be purchased with binding either on the left side or top. The book can also be purchased alone or as part of a set. Set includes pediatric occluding glasses and metal-framed adult occluding glasses.

When comparing visual acuity results with ETDRS, study results suggest the LEA NUMBERS® Low Vision Book has a slight advantage over the Feinbloom chart when testing individuals with vision impairment.
