Does "250" mean that it is +2.5 diopter correction, or that the amount of correction is unknown?

Yes, that is what it means. I did the same thing that Wanda did. When I went to the Optometrist and got bifocals for work I mentioned that I just got drugstore glasses for reading at home. He asked what power I was buying and I said 225's and he said "Well, next time you buy some get 250's which I did. I love these glasses, they look nice and fit comfortably. Get them.

I would contact a local eyeglass outlet for this information. If you are looking for reading glasses, I personally just went down to Walmart with a magazine and tried all the glasses until I found one I could read the material comfortably.

It is a step up from the 55-250. You can get closer to your shots from the same distance.

Yes, I think the right-hand diopter adjustment is usual. I admit I don't use it often as the improved adjustable eyecups and big bright eyepieces allow me to keep my glasses on. I do like these binoculars. I especially value their ability to focus close-up, so they work as well for the backyard feeder as out in the field.

Usually a 250 will end up with about the mid 230s. I can't say exactly how much.

i think not. minimum eye piece is 10X and minimum scope is 4X, so I think that means 40X, min. (I think!)

If you pull out the viewfinder you'll find a small dial. That's the diopter adjustment. It's great when you go from glasses to no glasses. Before you set it make sure you've actually had the camera properly focused on something first.

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.

It can not be predicted. Look on the inner side of the lens cap. It will be written there.

Sheryl; The first number (7, 8, 10, etc.) is the power or magnification of the binocular which means a 10 brings the image 10 times closer than the naked eye sees. So the higher the number usually means a better binocular assuming the lenses are of high quality. But a higher magnification also requires a steadier hand. The second number describes the size of the front lens. A 25 will be larger and therefore bring in more light than a 21 and is usually a better unit. So most people would opt for the 10x25 over an 8x21.

Should read 2.5X magnification. The large portion makes object look 2-and-a-half times bigger, and the small round spot at the center bottom of the lens maginfies 6 times.

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 :)

It depends on what your eyeglass prescription is. I spoke to my optometrist to see Whart general range is.

Hi Anthony,The correct magnifications are 1.5x, 2x, 2.5x and 3x. The magnifications in the current video needs to be updated. We sincerely apologize for any confusion.

It means the magnification is 2 1/2 times greater than what you see with the naked eye. The image is 2 1/2 times bigger than its actual size.

When I ordered the glasses, I specified that I wanted 2.25 strength, and that's what I got.

I am not sure but I believe it was 250 or 300. I did find it in the description when I researched it.

These numbers refer to the strength (magnification) of the lenses. Higher numbers magnify more.
