Do the +2 masks have an insert lens in the bottom? I am looking for a single lens, not a bifocal, that has +2 magnification. I was told that they all only have magnification on the bottom portion of the mask, which is not what I am looking for.

I think my lens are one complete lens at -6. I don't know anything about magnification at the bottom. They are not for reading, so I think they are one complete lens at whatever you order. I am very happy with mine.

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

The first few I browsed did have magnification - unfortunately they placed them each in different listings - if you scroll to the bottom to 'frequently bought with' there should be other pairs that have varied magnification...hope that helps!

We do not offer custom made lenses, we use only manufacturer supplied reading lenses in standard magnifications of +1.25, 1.50, 1.75, 2.00, 2.50, 2.75, 3.00, 3.50, and 4.00. Not all of these lens options are shown in Amazon's product catalog, but we have them. If you would like to mix and match different strengths in left and right lenses, we are happy to accommodate you. You would need to order a regular pair and then write to us through Amazon's messaging system to tell us how you want to customize them. Or you could order at our direct website (same as our seller name), select a standard lens choice, and then put your customization request in the "notes" section during checkout.

No magnification. I sent mine back. You can get dual zone magnification for $30 or so from other vendors.

I bought this accessory kit a few months ago when I first started off in photography.. I was looking for something inexpensive to go with my kit lenses that would boost what they could capture.. When they arrived, I connected them and found out that they were nothing more than pieces of glass.. There is no magnification or anything.. I'd recommend that you don't buy any of these.. Save your money and buy Nikon lenses.. I just bought a 50mm 1.8G from Best Buy for $199 and it is amazing.. I did tell the seller that they were nothing but glad and they refunded my purchase with no hesitation so I'm assuming they knew they were glass.. Hope this helps..

Standard Gunnar glasses have a +1.2 magnification to them, per their website:http://www.gunnars.com/gunnars-vs-cheap-alternatives/

A barlow is fine. I use the GSO Barlow that actually gives you two magnification choices... http://agenaastro.com/gso-1-25-2x-achromatic-barlow-lens.html

Unfortunately I could not find a bifocal mask with correction for both far and close up vision. I bought a Promate mask with +3 correction for close up vision with the intent of reading the pressure and depth gauges while SCUBA diving and seeing the screen of my underwater camera. However, it doesn't work well with the camera because I have to raise my head to an uncomfortable position in order to see the screen while taking a photo or a video. I also bought an IST mask with single +1.5 correction, which is fine for me for far away vision, but is only of some help for reading the gauges and looking at the underwater camera screen.

It comes with two eyepiece sets. I don't see a mm setting. One eyepiece says WF 20x . The other eyepiece says WF 10x/18. I did a little research online, and apparently /18 means 18mm. I'm not sure what the 20x eyepiece is. Until my son because interested a couple years ago, I hadn't used a scope since my college biology GM course; and now I'm learning along with him. I suspect life science majors, grad students, and professionals will need to buy better eyepieces. But these have been great to show my son prepared slides and teach him to be aware of a microscopic view of our cosmos. Hopefully our interests will lead us someday to considering better eyepieces in a year or two. But, if you're looking for more now, you may need to budget that into their purchase better eyepieces. Or you can contact the business and see if they would replace these eyepieces, add better ones, and for what price. This has been my only business with them, but they were remarkably attentive and responsive to this novice user.

Hello Joy,The magnification of this product is 2X. Complete information about it can be found at the following URL: http://www.opticsplanet.com/carson-magnifold-lighted-magnifier-mj50.htmlIf you need more magnification, try the more compact 5X magnification "Carson® 5x MiniBrite LED Lighted Slide-Out Aspheric Magnifier with Protective Sleeve (PO-55)" Also sold by Amazon.I own both of them and use them both of them everyday, and they are each extremely useful!I hope this is helpful to you!Matt K

2.75 is not a standard lens magnification offered by the manufacturer in this style, so most vendors do not carry it. Some vendors do carry it as a specialty item, however. The vendor LittleGorgeousThings does have the 2.75 lenses at this time, but it may not be listed in the Amazon product catalog as an option; you would have to contact them directly to get it put in your glasses.

Yes, it allows magnifications. If you don't want it, keep it 1x. It's very simple, just turn the ring near the eye piece to vary the magnifications. 1x itself is so large, you'll rarely use 3x which will go slightly beyond normal view and we have to move the eyeballs to get the wide view at 3x. I like this product, which has given me lot of advantages, like perfect view of LCD screen without extraneous light on the screen, helps a lot in quick focussing, which is just not possible without this product!

Yes, somebody here said +.2 or something like that.It is minor but present; makes screen seem just a little bit bigger.You can get them as prescription lenses if you need more.

Thanks! A lot of specific info.Yeah, I knew the NEX series can't handle the Maxxum lenses.I probably wouldn't be buying any more lenses cause that's why I want the Sony BODY, cause I already HAVE several Maxxum lenses. PLus I really like how they have the IS in the body, not the lens.I don't often shoot sports so that's not a problem to me.I did NOT know that Tamron was associated with Minolta/Sony. To be honest, the original reason I went with Maxxum was that I had trouble seeing well enough to manually focus (took me forever). So I'd probably let the camera do that, and just change the speed/opening.My daughter has a Canon 30D but BOY is that a heavy body!Well, thanks again. I'll prob be buying the A33 body next month.

Magnification is the focal length of the scope (in this case 650mm) divided by the focal length of the eyepiece. The shortest included eyepiece is 10mm. So with what's included the maximum is 65x. If you get shorter eyepieces or a barlow you can easily more than double that. But you'll rarely use such high magnification. Atmospheric distortions become very visible at high magnifications. It has to be a pretty clear evening for me to even WANT that much power. (On most nights the limiting factor is the viewing conditions, not the telescope...)

It only came with the two lenses. We sent back everything that came with it. We do not know what the magnification multiple is.
