Home Forums Hunting & Shooting Hunting Optics dioptric compensation

I have a pair of Swarovski CLs and I have run out of adjustment.Just wondering if it is an adjustment issue or my vision.I do wear glasses but not when using the CLs.I was thinking of sending them in for service but it could be me not the bins.I wear glasses mostly for driving (can't make out the road signs)otherwise I usually don't use them all the time.
The view is still very good but I know it can be better.
Should I be wearing glasses while viewing?I always thought bins were just a large set of glasses and could compensate vision.

I had the same problem with my right eye with a pair of Meopta binos. The meoptas ran out of adjustment travel just as the object was starting to focus, two of my other binos could get the subject in focus, but just barely.

I had a cataract operation and lens replacement, now I can focus the binoculars with far less adjustment travel.

So, maybe its your eye or eyes.

Last time(first time) I got glasses(for DL renewal) about 5yrs ago,they said no cataracts.I really like using the eyecups that's why I never tried with glasses.
I suppose I could just drag my lazy arse and pull them out of the safe and try for myself.
Contacts are out of the question unless they were bifocal,and that would drive me crazy er

Yes, you should wear glasses while viewing.

That's not going to happen.I tried ,not enough eye relief.

Better call Doug.

Because of eye relief on several very good binoculars, I always removed my glasses to use the binocular. I finally got tired of this (really a bad deal when sizing up game), and use only binoculars with long eye relief that will accommodate my glasses.

In buying a new binocular, eye relief is my number one criteria. I am very happy with the two I now have and use, a Leica Noctivid 10x42 and a Swarovski EL 8x32.

Yep, when I'm looking for something I always check Cameraland first.

Like GF1 mentioned, if you're wearing glasses, eye relief should be one of the biggest factors in bino choice. The quality of the glass, color, all the other stuff...really doesn't matter if they are hard to use. When wearing glasses, I love the Meopta 7x42's with 20mm eye relief. When wearing contacts, I love the Meopta 8x32's with 16mm eye relief. I can use the 8x32's with glasses but not with the ease of view that the 7x42's have.

I have the same problem. All my riflescopes are turned in as far as they will go. It’s your eyes, not the optics.

Well then you are not going to get 20/20 out of the binos....and Doug can't fix it..

Eye glasses give you best correctable vision....Bino's with glasses, do the same. Without your glasses you don't have the best vision and binos only make it bigger. The further you are from normal, the more noticeable it will be.

It seems that your binoculars just lack enough adjustment for your uncorrected vision (i.e. when not wearing glasses). Some people call it focus past infinity, or overtravel, or overdrive. That is, past infinity for corrected vision.

My favorite binocular is +4/-4, which seems to be on the lower end of the range, and are almost enough for me without glasses or contacts. However, I have owned several other binoculars with a wider range, and could use them fine without glasses.

I have heard that manufacturers can make adjustments to extend the range farther past infinity, at the expense of the other end. But I have no idea if that is actually possible.

How would the bino manufacturers correct for multiple different astigmatisms?

Nobody mentioned astigmatism, except for you.

Correct and the reason binos are not a large set of glasses as the OP may have thought.

And also why the more your eyesight deviates from normal, the less a bino will give the same clarity with and without glasses.

Jezus Fhuqk...simply shop for diopter corrections,that fit your blinkers. Opt 5/5,you Fhuqktards. Hint.



Just sayin'..............

Thanks, excellent info for those that can be corrected to 20/20. (And need no spherical or axis correction.)

It's pretty simple.

You also need to take the "dioptric range" with a grain of salt. It may not meet the power on your RX.
