Useful During Dark Adapted Tests

This flashlight allows you to have enough light in the room during a dark adaptation test without light adapting the patient.

By using red lights, the cones can receive enough light to provide photopic vision (namely the high-acuity vision required for reading). The rods are not saturated by the bright red light because they are not sensitive to long-wavelength light.
