alternating between glasses and contact lenses, and working a lot on screen, prone to headaches ... I tested, without being sure of the relevance of this kind of products ... and it works! more burning eyes, already (the change is immediate), more than a headache. Quench your taste immediately. The tint of the glass: the glass effectively, not only add a slight correction, is tinted. But it's still very natural, even working on the video or sorting pictures (of course, do not work with colorimetry !!!), it does not shock. You will quickly into reality! For all subjects people to headaches and attacked by light screens, to recommend. Even if it is a comfort that is expensive anyway.
