A little puzzled at first I still had offered this pair of Gunnar's because my new screens brighter well (LED requires). I often had a headache and / or itchy eyes that even with my LCD before. Now it's all over! Spending several hours a day on my computer (Games and work), it's just happiness to wear those glasses ... A little disconcerting at first yellow filter. But you soon get used to it. Very quickly! The glasses are also very lightweight so you hardly feel them. In short, albeit a bit pricey, but the fact of not having headaches than makes ... I recommend.
