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

there were two in the package ..I wondered if in case you lose one.. I was happy with 2 for that reason as they are tiny.2 double clips - someone wrote for each nostril no 2 actual sets if that makes sense... i did not ready anywhere that there were 2 in the pack but was happy with 2 in case i lost one .

2 at the same time or go see an optometrist and have a pair made with this type of lens. These glasses are helpful but not by that much.

Don't really know because I only use 2 pairs. Number of glasses used should not be a limiting factor. If nothing works, I suggest you reduce family size..Concerning previous comment on same issue, I swear only by genuine optima 3d glasses. Others may be cheaper but may not perform as expected.

I am sorry I can't tell you how many. It was given as a gift and I have never even seen it out of the box.

I am not sure I understand the question. These are the clearest, sharpest binocs I have ever had the priveledge of owning. All across the lens they are sharp and bright. A great deal for the money. You would spend $800.00 - $1000.00 to find a pair like them.

You only need one diopter ring for one eye. When you focus the binoculars, you're focusing for both eyes, but then you use the diopter ring to compensate for the different vision in the one eye. The other eye gets the compensation from the overall focus. You tweak the main focus and the one diopter until both eyes are getting the same sharp image.

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.

Yes, there is a diopter adjustment (very small) dial just to the left of the view finder.

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!!!

Hi! Just one. It is very bright though. If you hang it in a 12x12 room you will be able to see everything. Its bright enough to read by. Ive used it a lot already and really happy. I will be buying more when I can afford it

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.

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