Abstract
A system that includes an optical device intended to be worn by a user and a calculation module. The optical device includes a light sensor, the light sensor being located in an internal side of the optical device and in a vicinity of a front part of the optical device, the light sensor being configured to determine an amount of light that it receives, and the calculation module being configured to determine an amount of backlight received by the optical device using the amount of light received by the light sensor.
