tacky finish

It's not just on Kowa scopes. I have come across the same problem with 'painted' binoculars. As already mentioned, you can remove it. You could try talcum powder.

Optolyth Alpin cleaning.

Oh, why not? A lovely binocular and well worth the cost of cleaning.
Here I have to admit that I do that for a living so I will be happy to help.

Check collimation on a star

Try your new binocular at night. Look at a star and move your eyes aware from the eyepieces slowly and not very far. The star should still look like one.

faulty alignment

When a binocular is bumped or dropped, it is often the prisms that move. If the plate on which they are fitted, is a bit too big for the size of the prism than the images can be mis-aligned and...

In my opinion, eye strain is nearly always caused by slight misalignment.
It is not unusual for a new binocular, especially if supplied by post, to be out of collimation. A little horizontal error...

Hazy Alpin

It is a real shame that Optolyth no longer make binoculars.
Your Alpin should be better than the Russian but hazy prisms
will badly affect the image.
I would be happy to clean and realign.
