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

Just one. It's pretty focused so bright enough for reading our other fine work. You could put a higher wattage CFL or an LED bulb in it for more without any detriment.

No, not a pair. Order two of the same lens if you have the same script; but otherwise you must order them individually. I don't know how it reads now; but I ordered two of same lens since both my eyes script are the same. Also be sure that they will fit your goggles; I had to order the Platina goggles to match.

Maybe, if plus or minus 2 diopters is enough to allow you to see your menu clearly. It's usable for me but i could really use a little more than +/- 2 diopters.

80 is the total, there is only a knob for focusing. You can also adjust how close to the base the optics are with a knob.

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. I purchased this item for my fish tank filter, but it was the wrong size.

They adjust for interpupillary distance at the hinge. The adjustment is so wide, I can't imagine them not fitting everyone. Hold them up to your eyes and move them in and out until the two circular images merge into one. The interpupillary distance is set. Then focus them until the image in the left eye is sharp. If the right image is also sharp, the focus is done for that distance. If the right image is fuzzy, adjust the diopter ring on the right eyepiece until the right eye is also sharp. From then on, focus is done with the big wheel in the middle. Easy peasy.

The glasses are receivers of the IR signal, like a radio receiver, so there is no limit on how many you can use.at oncez.

It only came with the two lenses. We sent back everything that came with it. We do not know what the magnification multiple is.

Pull the eye piece out at far as it will go. The dioptric is on the left hand side near the bottom of the eye piece. It's very small and hard to find and hard to to get your finger in there to make the adjustment.

One. You really need Two. I am a DJ and use them at Parties. Very Funny to watch!

CR927, or equivalent, - it takes two on each side. That's 4 per pair of glasses.

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 :)

One for a single pair of eyeglasses. It's just doubled over in the packaging due to its overall length.
