How to Purchase an Ophthalmoscope
Ophthalmoscopes are one of the tools used by medical doctors and practitioners during patient eye exams. They are commonly hand-held devices that can magnify and illuminate the eyes for better diagnosis. Some qualities like extreme impact resistant casing and a wide range of aperture settings can make your job easier and more enjoyable. Other features like halogen lamps can aid a trained viewer to distinguish between veins and arteries of the eyes. Whether you want your ophthalmoscope in your pocket or on your belt, or prefer a wall-mounted version in your exam room, the availability of various ophthalmoscope designs means you can find the instrument that best fits your needs.Instructions

Determine if you need an indirect or a direct ophthalmoscope.
