Don't move! Hold very, very still!
One lense is easy to adjust and the other is very hard, so it's really difficult to get the glasses focused well. I'm thinking about returning them because I keep getting a headache. Plus, while watching tv, I feel like I have to hold my head at an odd angle to keep the screen in view. The glasses block all periphery, so if you're watching tv with family and want to interact, the experience is awkward because the only place you can look is through the lenses. I know that this should have been obvious, and I recognize that low vision aids often cut out periphery but the total tomb feeling while wearing these was surprising to me. I will say that when I get the lenses adjusted just right and hold still and sit exactly in front of the tv and not off to one side (which further complicates adjusting the lenses for focus) and I don't try to look around or find my glass of wine or pet the dog, they're great. Maybe the much more expensive ones are better.
