A foot-candle (sometimes foot candle; abbreviated fc, lm/ft², or sometimes ft-c) is a non-SI unit of illuminance or light intensity. One foot-candle represents "the illuminance cast on a surface by a one-candela source one foot away." This unit is commonly used in lighting layouts in parts of the world where United States customary units are used.

Reading glasses with lighting function

The application discloses a reading glasses with lighting function, and belongs to the technical field of glasses. The glasses comprise a frame, a lens, a temple, a power supply and a control system; the lens is provided with a light inlet surface and a lighting light source on the outer side, and a gradient scattering point is arranged in the lens to cooperate with total reflection to form directional and uniform light illumination. A Hall sensor is arranged in the frame to realize automatic power-off of any single temple folding; a bridge light sensor realizes coexistence of automatic and manual dimming, and manual dimming is prior. The temple is provided with a touch strip and a button, supports stepless dimming, 1850K candle light color temperature (harmful blue light is less than or equal to 5%) and 3000K warm white light switching and low power prompt; a front end flexible wing prevents light leakage; and double batteries are arranged at the back to balance the gravity center. The lens is integrated with multiple film layers such as reflection reduction and blue light prevention, and the illumination is uniform and glare-free, intelligent and comfortable, and the glasses are portable and suitable for reading in a dark environment.
