Lorgnette Pinhole Occluder

This occluder can be used to cover either eye and introduce a multi-hole pinhole to the uncovered eye.The pinholes provides a simple method to focus the light coming into the eye temporarily removing the effects of refractive errors such as myopia. If the use of the pinhole improves the patient’s visual acuity, refraction with Rx lenses will most likely correct the patient’s vision. More importantly, if the pinhole does not improve visual acuity, the examiner should search further to determine if ocular disease is present and causing loss of visual acuity. The pinhole occluder can also be used in testing visual acuity in Mydriatic patients. In this case the pinhole occluder compensates for the inability to contract the iris assisting the eye in obtaining a retinal projection similar to that of a non-cycloplegic eye. The drop-down pinhole feature is specifically designed to avoid inadvertent movement.
