It is a “digital device lens” a random made up term, because the lens designers use small amount of base in prism in the corridor to reduce the amount of required convergence. It has nothing to do with digital devices per se, but rather looking at anything, digital or otherwise, up close.
This may or may not be a good thing. Prism adaptation is a real phenomenon necessitating the continued use of prism when you reduce the muscular effort of your own natural convergence.
