The lens selector dial (diopter) allows the nurse to adjust a set of lenses that controls focus. The red filter facilitates the identification of pallor of the disc and permits the recognition of retinal hemorrhages by making the blood appear black. When the patient's pupils are dilated, a larger light may be used for the internal eye examination. The wide-beam light can be used when the patient's pupils are dilated for better visualization of internal structures.
