The Lorgnette Occluder (also known as a Mask Occluder) allows for either eye to be covered. The multiple pinhole attachment (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 in its ‘upright’ position due to an improved design. Strong, self-formed rivet for long durability.
Lorgnette Occluder is a versatile too that is avery popular because it provides so many features for Ophthalmic and Optometric exams. It can be held by the patient thus leaving the examiner’s hands free. Lorgnette Occluder is suitable for patients of any age, even children catch on quickly.
Furhthermore, the pinhole drop-in 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 diseasesis present and causing loss of visual acuity.
The pinhole occluder can also be used in testing visualk 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.
