I love wearing these glasses while I work! They're comfortable and versatile—I've received so many compliments on them :) As with most (all?) blue-light glasses, there is a *slight* colour difference when wearing them, but it's unnoticeable unless you're "looking" for it (I only noticed because a friend specifically asked me about it; I took them on an off and noted that colours were a little more saturated while wearing them...emphasis on "a little").
