The glasses are extremely annoying to clean. In my normal glasses, I can once over with the lens cloth and it is clean. This, however, has it even then any specks of dust and stains. Because you have to be very thorough. Otherwise, it's really pleasant to sit with these glasses in front of PC. It weakens the light from the monitor barely, but everything seems in warmer colors. After ~ 5 minutes, completely forget that you have these glasses on at all. And it takes longer to get tired eyes. Were they easy to clean, they would certainly be worth 5 stars.
