Good binoculars for their price range. Clear image, easy to focus. When I use them for extended viewing, my eyes get a little stressed. I mainly use them to judge approaching deer, to look out for coyotes, turkeys, etc. So quick scans take 2-3 minutes max, eye strain is not a problem. My eyes will feel a "pull" from continued use over long periods of time. They work very well for the price. If I lose or damage them, I'll buy another set of the same.
