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

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

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

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

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.

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.

It depends on what you'd eyeglass prescription is. You should check with you Optomotridt and find out what your prescription is and then get the diopter closest to that.Rich Signorelli

Very decent, for amateurs this is actually a very good deal. You must be aware about how to correctly adjust the diopter ring, which is probably the only thing that could make you think they are not working. To me, this product worth it.

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 .

Thanks for taking the time to reply. I suspected as much, so I have just been using one at a time. Nice to know that I needed to, and should continue to, in the wide angle range.

I believe it's 3x. It's been awhile but I was interested at the time so that my father who has macular degeneration could read.
