Abstract: A head-mounted display (HMD) determines whether a set of criteria is satisfied based on eye-related readings collected by a camera of the HMD and wirelessly transmits a set of messages in response to a determination that the set of criteria is satisfied. An attachment includes a set of light-emitting diodes (LEDs) and activates the set of LEDs to emit the light at the bleaching intensity in response to receiving the set of messages.
