Abstract

PURPOSE: To make possible electronical controlling of the quantity of transmission light for various rays and achieve practicable use by so setting the relations between illuminance and light shield rate in the sunglasses as to satisfy the specified conditions.
CONSTITUTION: The sunglasses are constituted by photo cells having photo detection and driving power source funtions, circuits for controlling the current and voltage from the photo cells, dim lens units whose light transmittances vary with voltage and current and a frame. Here, the illuminance and light shield rate of the lens units are so set as to satisfy formula 1. However, in the formula 1, A is given as the rate of increase per unit illuminance of the light shield rate.
