Precision Vision: ETDRS Illuminator Cabinet™ receives CE Compliance, PVVAT™ Computerized Visual Acuity Testing Software – Precision Vision


Precision Vision® is the world leader in quality vision testing products and the ETDRS Illuminator Cabinet™. We are committed to providing you with top quality products and service for your vision testing needs.

The World Standard ETDRS Illuminator Cabinet™

We are pleased to announce, that effective May 12, 2008, Precision Vision completed testing and documentation requirements to receive CE approval for the ETDRS Illuminator Cabinets. After passing stringent testing levels for emissions, our cabinet is classified as a Class 1 Medical Device to be used in Hospitals, Clinics and Doctors offices throughout the European Union. All ETDRS Illuminator Cabinet™ accessories (charts, bases, lamps, and filters) are also CE compliant.

The ETDRS Illuminator Cabinet™ is the world standard used in research, trials and general practice. It has been for over 30 years. In fact, Precision Vision was put to task at the inception of the ETDRS study. We provided this cabinet as the first commercially viable standardized Illuminator Cabinet, as well as the original ETDRS charts. This retro-illuminator cabinet is designed to provide a uniform illumination of 170 cd/m2 across the test face.

Today, ETDRS charts are available in various contrast levels, test distances, and optotypes. Our Illuminator Cabinet is also available in both the popular standard beige color, or the new cobalt black finish. A mesopic filter to test patients at low light conditions of 3 cd/m2 is available. Also, in response to customer requests, Precision Vision will soon provide a filter for testing at 85 cd/m2.
