Indirect binocular ophthalmoscope

An indirect binocular ophthalmoscope is a head-worn, electrically powered instrument used by eye care professionals to examine the interior structures of the eye, such as the retina, cornea, and lens. It allows the examiner to view the patient's eye from arm's length while using both eyes simultaneously to achieve stereoscopic vision. The device provides a wide field of view and produces an inverted, magnified image of the ocular structures for detailed clinical assessment.

These devices are typically supplied as complete systems that include a headband or spectacle frame, illumination source, lenses, and filters to reduce glare and reflexes. They are designed for professional diagnostic use in clinical settings and rely on electrical power for illumination. The category encompasses both fixed-focus and adjustable models, with variations in mounting style and light source technology.
