I wear glasses for an astigmatism. When taking photos, I find that my eyes lose focus almost right away, since one eye is closed and the other is looking through the viewfinder.
This happens whether or not I wear my glasses, so I usually just wear them.
Naturally, this makes it difficult to a) evaluate photos and b) know whether or not I'm actually focused properly. Photos will look fine to me on the camera but then on the computer they're unusable.
Has anyone else experienced this and/or have any ways to deal with it?
