Using commercial glasses for CVD correction with digital displays

The development and commercialization of aids for improving, and sometimes allegedly correcting, the discrimination of colors,in color vision deficient subjects,has increased in the last few years. Producers often claim such devices are also effective in improving the experience of color vision while using digital displays, sometimes even selling specific types intended for indoor and display monitor usage.In general, the underlying mechanism of these physical ocular filters is to reduce the amount of spectral energy in specific bands of the visible spectrum. The most common digital displays rely on the emission of three light sources limited in band occupancy, so different filter types might be more or less effective when used with digital displays rather than when observing real scenes or pigments.This paper aims to comment and evaluate the effectiveness of such filters when used with different types of digital display technologies. We discuss whether inter-device variations (namely different gamuts) might alter the chromatic sensation of users.
