An adjustable disc having a hollow body frame rotatably secured to said board body, a first lens being mounted to said body frame and corresponding to the viewing window and a second lens being mounted to one lateral side of the board body and covered the viewing window and corresponding to said first lens. Thereby rotating the adjustable disc causes a variation of the polarized angle formed by the first and second lens and thus change the light transmittancy of the first and the second lens.
