I've got -2.75 & -1.75 eyes. Should I round up or down to the nearest diopter? For each eye. 2.5 or 3 for the 2.75 eye & 1.5 or 2 for the 1.75 eye?

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.

Two easy ways to solve this issue: There is a company called Platina (they also sell on Amazon) that sells the Corrective lenses separately so you can go that route if you like but it is more money. Second option: determine which is your DOMINANT eye and buy a pair with that correction. 99% chance you will NEVER notice the difference since your dominant eye controls most of your "vision"

So you have the option to have a different strength for each eye? I did not when getting swim goggles and went with something in the middle, so in your case, either 2 or 2.5. I have one eye too strong, one not enough, but that does not seem to be a problem.

The CPC is listed as using 1.25" star diagonal. You should be able to use the 2" star diagonal in this kit to use the eyepieces in this kit. You will need to remove the 2" diagonal and reattach your 1.25" diagonal to use your 1.25" eyepieces.

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.

NO. 10x25 will work but wont work well, 10 is the magnification, 25 is the radius of incoming light, its very little, you need 10x30+ binoculars for wider field of view

That's the method we used when buying my daughter's goggles. She ended up with -3.625 (R) and -4.25 (L) so we split the difference with a -4 prescription. She says they work well enough for her, and she has to be read a white board to get her workout during swim practice.

The first number is the magnification and the second number is the lens diameter. The larger the numbers the more magnification and light gathering potential.

That has never been a problem for me. I see fine. Would not need to adjust them. At first I thought that would be a problem but it was not. However I have 20 20 uncorrected vision.

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.

Actually the claimed eye relief is 17.5, which I find just about totally adequate for my use with glasses. So long as I take care and don't let them move around on my lenses, I can see the full field of view, which I haven't come close to seeing with any other optics in my life.

Depends on what your prescription is. The camera has a built in -3.0 to +1.0 diopter adjustment. You want to buy the one that will allow you to match your prescription.E.g. If you wear +2 prescription, get the +2 and dial it down by 1. You would only need the - if you have to go further than the -3 that is built in. However, I have found that I do not use the diopter. When I have my glasses off, the images on the LCD are blurry. So I shoot with my glasses or contacts, so I can still view the images on the LCD.Hope this helps you decide.Chris

I am not sure if you are asking how low can you go as in is there lower then 1.8, BUT aperture can go as low as 1.2 which is EXPENSIVE. 1.8 is just fine if you are thinking cost effectiveness.

i've found 1 1/2" is the "best". That close, always manual focus if possible.

both .12 and .2 ! if u want farther reach use the .12 but if u want accuracy then u use .2.,, i prefer using .2's

The 1.25 dimension is the standard telescope eye size for most scopes. I to have a C90 and purchase a "hybred-diagonal" (.965 to 1.25). This allows me to use all of my 1.25 eye pieces on my C90. Hope this helps.

Id say pick the 17-35 if you intend to stay on DX size for another 5yrs... the 50mm covers the middle of the 24-70 so moving your feet will cover that distance, but the 17-35 will allow for group shots and landscapes/buildings... the 24 will limit that somewhat.... my2cents!

I set the focus for one eye in the non-diopter lens with the center focus ring, then looking at the same spot with the other eye, adjust the diopter adjustable lens to focus. Once this is done, you should be able to focus for both eyes with the center ring. Each person may have to adjust to suit their own vision, but if only one person uses the binoculars, they shouldn't have readjust the diopter to focus with the center ring. Note your diopter position for the purpose of quickly realigning if someone changes your setting,

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.
