The entire Gulden occluder family is molded from strong, lightweight ABS plastic, with an easy cleaning gloss finish. Occluders are used to cover one eye during testing or treatment. Clip-on occluders are designed to fit on any pair of reading glasses.

This new occluder uses a lightly frosted, scratch resistant lens that degrades the acuity of the non-tested eye while not inducing suppression effects. The reading eye is thus tested with an absolute minimum of interference from the other eye.
