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

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

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

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.

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.

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.

Hi, I said I would check the use of the MaxTV glasses with my 4.25 Diopter contact lenses removed.I did, the focus adjustment did NOT go quite far enough to give a sharp focus. It was very close,but not quite there. If you used a two diopter, I don't think you would have a problem, even a 3 diopter would probably work. So for what it's worth. Ang, again, they work as I wanted them to.

Hello; This is an 8 diopter lens. A diopter changes the focus range of your lens. Diopters come in powers from +1 to +5 (that I've seen). They're also stackable: you can put a +4 diopter on top of another +4 diopter, and conveniently that gives you the effect of a +8 diopter. (Quality does suffer when you stack.) The higher the number, the more powerful the diopter. The more powerful the diopter, the closer you can focus. Specifically: divide 100 centimeters by the diopter power. That's the maximum focus distance of the diopter. A +5 diopter focuses at 20 centimeters or less. A +2 diopter focuses at 50 centimeters or less, so an 8 diopter lens would focus around 13 centimeters or less. Hope this helps. Remember, this lens works when you are in full telephoto.

Just one. It works for me because I have very limited space anyway. Take that into consideration for your needs.

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.

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.
