Q: The plastic optics on these binoculars are not uniform. This makes them effectively useless and hard to focus. When the middle is focused, the outside edges are blurry, and when the outside edges are in focus the middle is blurry. I bought 4 pair of these binoculars for my kids, and every single one of them are unable to be focused properly. I am familiar with optics and binoculars, and am aware that plastic lenses don't have the same quality as glass, and that these are cheap ones and my expectations should not be high. But the lenses aren't even shaped the same from binocular to binocular. These are spectacularly bad.
A:
The optics on these binoculars are spectacularly BAD. only 50% of your view will be in focus at any time.
