This 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 fellow eye.
The examiner is also able to see the non-tested eye through the frosting. This is important to see if the patient giving acuity results is “squinting” the fellow eye under the paddle. Likewise cover testing is made more reliable and informative because the examiner can see the movement of the covered as well as the un-covered eye.
The Lorgnette Occluder (also known as a Mask Occluder) allows for either eye to be covered. The multiple pinhole attachment, with 17 holes (1.5mm), allows for quick access to a pinhole view. The pinhole attachment can be moved up providing a clear opening for view. Unlike some Lorgnette Occluder's on the market, the attachment will stay in its "upright" position due to an improved design. Strong, self-formed rivet for long durability.
