I have graduated lenses - Would I be best advised to order bifocals? And, how do you incorporate Cyl and Axis measurements?

Hi Todd, I did not see option to order bifocals so I can not comment. Best..

I do not know what 'cyl' and 'axis' measurements are, but, here is what we did:1. when ordering Speedo goggles, we got the +/- number, from our opthomologist.2. when ordering the ProMate snorkeling mask, we selected the the color and then selected the appropriate eye-adjustment (my son is nearsighted) from the "size" pull-down menu on the ProMate scuba options.3. My 13 year-old son loves the mask and was our family underwater photographer in Cozumel.

I have graduated lenses also; however, I just went with single vision lenses in my mask. Don't know about Cyl and Axis ... I didn't bother (even tho I have an astigmatism) and they worked great

I wear trifocals and the single lens correction worked just fine. I wasn't close enough to need the extra correction even when I was about 3 feet away.

check the scope's spec. sheet it should have the diameters of the lenses on it.

You just need to know what your basic prescription u s and order a lens close to that. It worked for me as nd I am very nearsighted.

The thing to keep in mind about these is that they are compact. So the eye pieces are set wider than the view lenses. Turn them around.

While the 71008 may or may not be adjustable the 71012 is from 25x to 100x. My purchase has been a real source of joy, excitement, learning and revealing! My children frequently use them for lunar observing. My wife loves animal watching. One suggestion if I may. Purchase a quality tripod! The glasses are not light and for higher magnifications a good solid mount is a must in order to keep your objective is sight. It's well worth the money! I hope this helps and I hope you enjoy your glasses witchever way you choose to go.

Blue lenses are excellent for all types of light. We currently have the +2.5 in stock but not the +3. Hope that helps.

Definitely used it through eyepro- take the time to fully focus for distance viewing beforehand to save time though. If you use prescription lenses/inserts it will work with you as well, again take the time to focus it both settings in a "stress free" environment.

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.

Start with lower magnification eyepiece(20mm). During the day practice on focusing on large objects. It's also the way to align the red dot finder. I bought this scope for my grandson . He loves it

I'd start with a good 2X Barlow lens. It doubles the mag of all your other eyepieces...

I use them at my computer since it is somewhere between the "distance" and the "reading" of my bifocals, but I don't think they would work in your case. Try maybe some magnifiers that you can wear on top of your glassesHead Wearing Magnifier Can Be Used Hands Free And Worn Over Glasses. Has Dual Magnifying Power.Also, tool suppliers provide such magnifiers for close work like you describe.

You need to look at the threads in the front of your lens. There will be a notation of the size required there

I have bifocals too and they work fine for me. Haven't had a problem. They seem to fit over the lenses with enough room to spare. However, I think that would depend on the size or your prescription glasses. If they are larger in size, the goggles might cause the trouble you mentioned. Good luck. I bought 5 pairs of these.

I currently have the 8 X 42 Nikon, and formerly owned a B & L Legacy, about 10 years ago, before the merger. It was a fine binocular at the time, could not comment on the quality control at present. I do know that the Aculon is excellent ergonomically, and the QC is very good.

The eye piece view is crisp and clear, had problems at first getting them to focus but playing with them I found that if I use my 2x Barlow lens the focus was great, so if you think this might be a problem I would suggest you take this advice when choosing your lenses. I ordered two 12mm lenses to go with the bino viewer and it cut it down to a 6mm because of the 2x Barlow.

The lenses in these are not as sophisticated as the ones you would get from an optometrist. Consider the price! As a rule, I normally go down rather than up, so in your case I would get -3 (rather than -3.5)

You will need to purchase a adaptation set. I previously had one for other lenses/filters, so it wasn't a problem, but I can see where this might be frustrating if you did not have these.
