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.

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 :)

I think the 10mm & 20 mm eye piece comes with the telescope, & a basic laser finder, you may find it more enjoyable to order a 2x barlow extension, That mostly makes it a complete setup for the quality the scope

Hi, I need two loupes 3.5X and s(280mm - 380mm), how can I order this item, please I need help.

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

Because of the difference I would suggest buying 1 pair in each of the diopters you need and swapping out the lenses. For me the difference was only 1 point so I went up a half. They've worked out great.

I agree with you, measure the Objective Lens and see if they have the size you need, no doubt they will work. Make sure to measure and convert inches to millimeters.

Please go to Nikon.ca and request their lens application charts to get the right answer

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.

thanx a lot for your response! i already ordered the 55-210 mm lense, lets see when it arrives.

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.

Hi Denise I would start with a skylight 1a or a polarizing filter to protect the lens the lens will have a sign and a number underneath the sign is a circle with a diagonal line through it going from top right to bottom left followed by a number 46 52 67 etc this two figure number is the filter size for that lens

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.

BonGiorno, You need to provide info on what you have already. Do you have rails? RedRock sells gears for your lenses. Determine the circumference and buy accordingly. I needed the A and B gears from RedRock, purchased through B and H in New York.

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.

They do have a 2.5 and 3.0, but they are all bifocal. The upper part of the lenses are plain, no correction.

The Raynox is very good value for money and the lens quality is quite good in the centre, less so toward the edges. That said, your macro lens is excellent and you would need a very good reason to want to use the two together. If you want more magnification I'd reverse a 50mm standard lens on the front of your macro. The rings to do that are cheap enough.
