right using direction and may provide for best image quality;
2.Keep the lens centring on the patients pupil;
3. Hold the lens far enough from the patient's eye so that the retinal image has the same diameter with the lens;
4.Keep the illumination sources as dark as possible to minimize reflections and image contrast;
5.Keep the lens clean to minimize glare from the lens surface
