The BPI UV Safety Analyzer allows patients to see for themselves how effectively their own lenses will filter UV light. Lenses (or lenses in frames) are tested by placing them under the sensor. Immediately the signal light display will indicate either danger, caution, or safe. Ideal for the waiting room or dispensing area. The BPI UV Safety Analyzer has a durable and attractive powder coated finish. A black, cushioned PVC mat protects the lenses and frames from scratches.
