The OPTEC 6500 is a precise vision testing device that can be use to test for distance and near acuity, contrast sensitivity, stereopsis, color vision and potential acuity.

The OPTEC 6500 provide precise illumination ,which continually controlled by a microprocessor for accuracy and repeatability of the tests.

The Exclusive LED (Light Emitting Diode) system allows complete homogenous illumination that eliminates hot spots on testing slides, which can create inaccuracies of test results.
