These 3D DLP-Link glasses are pretty comfortable, even when wearing normal glasses. They fit perfectly, they are light in weight, and the battery is long-lasting. I have watched several movies and haven't had to charge them yet. They darken the image a little, but it's hardly noticeable. They take half a second to synchronize, and even if you move your head, they stay in perfect sync. When I bought them, I didn't think they would work so well. They're just perfect for me. In fact, I have two pairs!
