Since the 1970’s Precision Vision has built a reputation of producing the most accurate and most durable vision testing tools available. In the 1980’s we printed the first ETDRS cards and produced the standard ETDRS illuminator
cabinet. Since the 1990’s we have carried a variety of Low Vision and pediatric testing tools.
This introduction, written by noted Vision Rehabilitation Researcher Dr. August Colenbrander, is meant to provide some guidance in selecting from the vast array of charts and devices available.
It is divided into several sections:
A – Visual acuity
B – Letter chart measurements
C – Near Vision and Reading
D – Contrast Sensitivity
E – Low Vision tests
F – Pediatric tests
