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 C5 comes with a 1.25" correct image diagonal. To use 2 inch eyepieces would require a 2 inch diagonal however there would be some vignetting in the eyepiece as the opening in the rear cell is only 1.25 inches in diameter. Advise to stay with 1.25 inch eyepieces.

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

It depends on what you'd eyeglass prescription is. You should check with you Optomotridt and find out what your prescription is and then get the diopter closest to that.Rich Signorelli

You can choose between 60, 90 and 120 deg angles in the menu. Even the 120 isn't really fish eyed where as normal fish eye lenses distort around the edges. Hope this helps.

I think -4.0 and -4 are the same. If you are near-sighted, you should choose negative.

Contact Splaqua. I have a smaller deviation in my correction , and in this situation it is suggested to go with the lower number. I know that Splaqua, and probably others, will help with getting the proper correction for each eye in circumstances that call for it.

The pulp adjustment number doesn't need to be exact. It's more of an art than an exact science. I haven't noticed a major difference between using 1 or 2 for fruit. You will notice a difference between 5 and 2.

I would double check with your Doctor as this is a question better answered by your optometrist.

Michael, Not sure exactly how much 1.2 is, but the adjustment is fairly large on the right eyepiece both + and - As a test .. I set the right eyepiece at max (-) and used my reading glasses 1.75's in the eyepiece to bring the field back to normal focus, ie left in focus, right at max - and the 1.75's on the right bring them both back to even focus. They are great binoculars and they perform very well for the weight and compact size. Hope the info helps.

Pull the eye piece out at far as it will go. The dioptric is on the left hand side near the bottom of the eye piece. It's very small and hard to find and hard to to get your finger in there to make the adjustment.

There are three lenses which can be stacked for greater magnification. Using the first lens only it's about 8-8.5 inches. Add the second lens and that drops to about 4 - 4.5 inches. Add the circular lens (for the right eye only) and it drops to about 3/4 - 1 inch. Hope this helps.

Hello L., Unfortunately, these do only come in negative diopters. We do have -8 but not +8. Sincerely, Roy Lazarus Trivillage.com

What I was told with 3.5X loupes is the focal distance should be at least 24-36". I must admit, I was "off" until I finally got myself to hold my head away from the patient at least that distance. Otherwise, everything is blurry. I'm also trying the 2.5x loupes now.

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.

You need to know your glasses prescription. If you're nearsighted, (need correction for distance sight your rx will be a negative number. The lenses come in 0.5 increments. For example I have a -3.75 correction. Since it is in between correction options I ordered a -3.50. (If your in between order the lesser strength). If you are far sighted the correction will be a +.(ie reading glasses). Hope that helps.
