When you process to order, there are bunch of options for you to choose. 2.5 means 250. I hope this is helpful.

It shows one but has option for up to four I believe. I used three in my installation.

when they say a certain amount, that is how many individual light emitting diodes it has.

What I do remember is this: it is a 5 diopter lens which has a focal point of 3"-5" with a magnification of 1:2.25. So far this has worked well for me.

1.5x with the first lenses. 3x with the second flip down lenses. 10x with the loupe. You need to be from 6" to 1" away to get focus. Would not recommend for folks with movement difficulty.

Just one, but they are well worth the price. You can get a few and rotate them out. :)

Only one pair, I ordered 4 pair and glad I did. Grandkids come over to watch 3D (I have 2) and PaPa and I watch with them. Well worth the money.

only around 8 but I don't actually realize that many. I don't have the opimum agial to get what I should and it is winter time when the sun is not as good a source. I have not mesured the answere either. So I am not getting more then about 3 at most times right now.

One! If you want another, you can buy it separately. I bought the red light head separately and I swap them over. But to treat acne, blue light head is enough.

I don't remember. I returned them, the ones they sent me were defective. When you looked through them you could see two of everything, no matter how or which way you tried looking though them

I don't know, but I've moved on to Splaqua corrective swim goggled--better deal, lot of different diopter corrections, they come with the lens in and they are cheaper.

I looked up the definition of diopter. It made NO since. The light has little rings to magnify and it is not all that good. It is a good light and I do use it to pull splinters and rearly read small things. I like it!!!

CR927, or equivalent, - it takes two on each side. That's 4 per pair of glasses. (The question was asked previously and answered previously by 6 respondents. It can sometimes be hard to find similar/identical questions and answers. Amazon needs to make improvements here.)

These binoculars hinge in the middle and the IPD ranges from about 55mm minimum to a maximum of 70mm at the widest. I hope this helps.

Yes - this pair allows for diopter adjustments, which you calibrate when you first use them out of the box (it may make focusing difficult for other eyes than your own, like when you lend your binos to someone else). I think the paperwork included has directions, and if not you can google how to do it :)
