What are the advantages of wide-angle birding goggles?

Wide-angle birding goggles have three advantages:
1. The birdwatching scope can zoom, that is, if the distance between the bird and the observer changes.
2. The focus can be adjusted to prevent inaccurate focus. The birdwatching scope has a relatively large field of view, which is of great benefit for observing and finding birds.
3. It is convenient and fast to change the field of view of the bird-watching scope. You don’t have to worry about the birds moving east quickly and not being found.
