). I usually wear my glasses when birding, and yes, "alpha" bins are well worth the effort. (P.S: By "alpha", I donīt necessarily mean very expensive...there are lots of optically top-performing binoculars out there that donīt cost the earth).hello forum ,
would it be fair to say that alpha bins are wasted on someone with poor vision ?
what do you think ?
No.
I think if someone already has poor vision they need all the help they can get if they still have some useful vision say for birding.
The usual places the "top bins" help out is in difficult light situations (close to the sun or in overcast). They can also be brighter (which may help some ... or possibly hinder others).
I'd try out a range of bins and see when they find easier to use.
Picking the right exit pupil size might be important for some (regardless of overall bin quality). Perhaps lower magnification (7x) might help others.
The details depend on the individual user.
I suppose it also depends on what kind of poor vision weīre talking about. Coincidentally enough, I had an eye-test today...my optician assures me that binoculars will correct for my mild short-sightedness, but not for my astigmatism. (I guessed this to be the case anyway....). I usually wear my glasses when birding, and yes, "alpha" bins are well worth the effort.
