ASF Mask Occluder

Description

The ASF Mask Occluder is a specialized diagnostic instrument designed for ophthalmic examinations and visual assessments. This manual, portable device is primarily utilized to distinguish between reduced visual acuity caused by refractive errors and that resulting from more serious ocular pathologies. It serves as a fundamental tool in an ophthalmologist’s diagnostic arsenal, aiding in the rapid screening of visual acuity impairment.

Constructed from durable plastic, the ASF Mask Occluder features a black finish and a short angled handle for ease of use. The device incorporates a multiple pinhole feature, which can be activated to create a full monocular opening [cite: SKU]. This pinhole effect functions by narrowing the beam of light entering the eye, thereby reducing blur, blocking peripheral aberrations, and increasing the depth of focus to enhance visual clarity. The occluder can be used as a mask or a reversible occluder during examinations [cite: SKU].
