Question: best fit for low vision 0 to infinity?
Document: Our low vision toddler found these easy to use. She was able to see animals at the zoo and birds in the trees without needing a grown up to readjust the binoculars over and over.
These are amazing! I'm an avid hunter and outdoorsmen and these binos are up there with the best of em. I took them to the deer lease with me a few days after I bought them and they performed beautifully. The PermaFocus feature is crystal clear at essentially every yardage an outdoorsmen would require. And they were fantastic in the low light atmospheres of dusk and dawn. For the price I bought them for ($60) you can't really beat this deal.
I guess I should have read the fine print more carefully. These binoculars have no focusing ability whatsoever. To be fair, they are (somewhat) in focus at considerable distance to infinity, but I can't adjust them to my particular vision (so they're never exactly in focus for me at any distance), and they're of no use at closer distances. I should have bought the Nikon version.
this replaced one that was dropped-very good buy for the low cost!
With the Perma Focus feature, any distance less that about 150 feet will never be in focus. From 150 feet to infinity they are great.
These worked beautifully while hunting. Good in low light and crystal clear during the daytime. Highly recommend these for the hunter on a budget :)
I initially bought a pair of these binoculars on a trip to Yellowstone for wildlife watching. They were a spur-of-the-moment purchase and I appreciated the price. The binoculars surprised me with their clarity and brightness, even in low-light conditions. When my father-in-law was getting ready to celebrate his birthday we purchased another pair from Amazon for him. Amazon, as usual, had the order to him on-time and the price couldn't be beat.
The binocular work very well.They are very bright.They are the the best binoculars that I have used.They are a little hard to hold still.
This is our second set of two. Over a period of 7 years the previous pair got dropped or jostled and stopped being clearly focused. We take responsibility for the damage as we carry these things everywhere. I got a pair for my sixth grade students to watch the 70 turkey vultures that roost outside of my classroom (something to do with low test scores? ).They use your own eyes to focus as you move. They are great for following moving objects because you don't need to worry about focusing.
The Bushnell PermaFocus Wide Angle Binocular is the best  general purpose binocular a person can own.I works equally well with or without glasses.
Answer: Fixed focus, so not good for close range (up to about 30 feet or so
