The occluder is a simple way to focus light like a pinhole camera and temporarily eliminate the effects of refractive errors such as nearsightedness. Since light only passes through the center of the eye's lens, lens shape errors (refractive errors) have no effect while using the occluder. ➤ What does the pinhole occluder do? The ophthalmologist, orthoptist or optometrist can estimate the maximum improvement in a patient's vision that can be achieved by lenses designed to correct refractive errors. This can be used to distinguish vision defects caused by refractive errors that improve when the occluder is used from other problems that do not. The pinhole occluder can also be used to test visual acuity in mydriatic patients. In this case, the pinhole occluder compensates for the inability to contract the iris and helps the eye maintain a retinal projection similar to that of a noncycloplegic eye. ➤ How to use?Squinting and looking through a tiny hole made with a finger works similarly to a pinhole occluder by blocking light through the outer parts of the eye's lens. An improvised pinhole has a similar but better effect. The same principle was also used as an alternative to prescription lenses: a grid of pinholes is mounted on a glasses frame and worn as pinhole glasses. ➤ Differential diagnosis: Pinhole deterioration of vision: macular diseases, central lens opacityStatic vision with pinhole: amblyopia\u003c\/p\u003e \u003ch3\u003eProduct Features\u003c\/h3\u003e \u003cul class=\"a\"\u003e \u003cli\u003eMultiple Pinhole Occluder Flipper made of highly impact-resistant plastic.
