Abstract
A head mounted display includes a lens unit, at least one lens temperature sensor, an environment temperature sensor, an environment humidity sensor, a temperature controller, a housing, and a display unit. The lens unit includes a carrier having a touching surface and a back surface opposite to each other and two lenses disposed on the carrier. An enclosed space is formed between a user and the touching surface. The at least one lens temperature sensor is adjacent to the lenses, and the sensors are all disposed on the touching surface. The temperature controller is disposed on the back surface and increases or decreases a temperature of the enclosed space and lens temperatures of the lenses according to sensing actions of the at least one lens temperature sensor, the environment temperature sensor, and the environment humidity sensor, so as to adjust the environment temperature and humidity of the enclosed space.
