Good-Lite LEA Numbers Low Vision Book
The Low Vision Booklet with LEA Numbers was created for the testing of severely visually impaired children and adults. This complete book includes testing for 10', 5', and for near vision at 16". 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 booklet can be purchased with binding either on the left side or top. 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.
