Flexible plastic screen for glasses, sunglasses or helmet faceshields with controlled light transmission based on applied electrical voltage. The screen consists of two transparent flexible conductive polymer electrodes disposed and an electrochromic layer disposed between them. The electrochromic layer is a homogeneous mixture of active electrochromic components dissolved in a polymer matrix. The electrochromic screen is operable to vary the light transmission of any wearable electro-optical devices, such as the glasses, for creating an effect of a blackout for augmented/virtual reality glasses.
