    I have become increasingly annoyed with the onset of the middle period; where muscles atrophy, hearing diminishes (selectively) and eyesight deteriorates. I dislike wearing my glasses, especially outside with the camera: but how else to see the menus etc?

    I tried bi-focal glasses, same problem as before, read the menu, push them on the head, focus and then try to grab the glasses as gravity takes over.

    I recently tried bifocal contact lenses, but the results, for me, were inconclusive. This afternoon I went back to the optician and trialled 'Mono Vision'. One eye has a reading strength lens, and the other has a distance lens. My master eye is the right, so that has the distance lens, the left has a reading prescription which is the eye I use for the diopter, the diopter is of course adjustable.

    It works! I can now use the camera without hindrance. So if you also hate your glasses, and can wear lenses, why not enquire about Mono Vision. :smile:

    I'm glad you found something that works for you. I am getting near that point, still need the glasses to see distance, and have all the diopter adjustments set accordingly. Increasingly, I have trouble reading, which means the menus are quite small without reading glasses. I have resisted bifocals. I don't think your solution would work for me as I am very sensitive to script differences between my eyes. Both have to be the same corrected end point, or I get headaches.
    Glad it works for you and maybe others will benefit too.
     
  3. Hey Rob,

    I'm just curious to know how long it took you to adjust? I tried it once and just could not get used to it so I stopped wearing the contacts or should I say, contact.

    I have had one other person tell me that they adjusted to it just fine.
     
  4. I have been wearing bifocals for some time now and have not problem with using they when involved in photography. I did discuss the mono lens concept with my eye doctor but decided against it because you lose your depth perception.

    You know, I've noticed this selective hearing loss too. It always seems to happen when my wife gives me another chore to do.

    I've been wearing progressive bifocals for about 15 years and recently had a prescription change. I'm having a devil of a time trying to see clearly. There is a very narrow window of clarity in my new glasses. Which, of course, makes for some interesting photos!

    Ty, I wandered out of the opticians, drove home, walked the dog etc without any problems. However some people are unable to process the different information quickly enough and end up with disorientation.
    Gordon, I have not experienced any altered depth perception. The best thing is being able to lift the camera to the eyes without obstruction, lower it, read the data/screen and also see the subject in the distance. No more smeared vision in the rain either.:smile:

  9. Paul, I would think that with only one eye looking at distance objects there has to be an impact on depth perception.

    I used to teach instrument flying so find the adjustment to single distance vision relatively straightforward. It's not as if the 'reading' eye is blanked off; it's still attempting to focus, but vision through it is somewhat blurred.
    In normal useage, and it's only been 48 hours, I find that my balance is unaffected. I don't trip or bump into things, until I leave the pub.:tongue:
    The slight distortion experienced with one eye as a reading prescription is adapted to by the brain. It will be quicker and easier for those with youth on their side.

    I would seriously recommend an appointment with a lens specialist, and give it a try. Rain does not bother me anymore! Using the camera over the past two days has been much more fun. No swearing as my glasses contact concrete.

    Driving at night would be a problem due to a slight reduction of depth perception. This evening I got back just before dark and was aware that I was working harder than normal to distinguish the road, and distances especially in shadow. Go on..........give it a go, your interest is piqued!
     
  12. Hi Rob,

    Sorry about refreshing an old thread some 5 months later, but I was wondering if your experience with the mono-vision contacts still works for you? I just returned from an eye doctor apppointment to update my glasses prescription, and I requested a sample pair of contacts to try out.

    I wanted to go with progressive contacts (I have been wearing progressive glasses for over 3 years), but the doctor indicated that he has seen very little success with them and recommends the mono-vision method instead for someone like myself (farsighted, unable to clearly read print up close).

    I am dubious about the mono-vision contacts. I am much like what Baywing described earlier. I have less eye fatigue and no headaches when both of my eyes are "calibrated" together. This all may be a moot point if I am unable to get the contacts into my eyes. I have had that issue before on previous attempts.

    I have noticed that I have been shooting less and less the past 3 years. I can see fine through the viewfinder with my glasses off, but I cannot make out the top and rear LCD panels and buttons. I got by with by last film SLR because I knew it pretty well, but that didn't stop me from making a lot of technical mistakes.

    Anyway, I was curious to hear about your experience of mono-vision contacts 5 months later.

    Thanks :smile:

    I have been wearing bi-focals for 3 years now... Man getting old sucks sometimes... but for the most part I haven't had any problem shooting with them.
    The reason I say that is that I have the viewfinder adjusted so when I look through the top part of my glasses everything is sharp.
    Now as I mentioned for the most part, the last pair I bought the lenses are a little smaller than the rest I have had and the stupid line tends to be to high and gets in the way.
    So when I am shooting I just wear a different pair with a larger top part of the glasses so I can see.
    The worst part for me is that 2 years ago I found out I have diabetes and once I got my sugar under control my vision improved (that is good!) but I end up having to change my Rx more often now which is a lot like Lens Lust, expensive.
    In fact it is time again to go see the eye doctor.

    my Two cents worth...

    Several years ago, I wanted to go to contact lenses because of my camera use. The Progressive lenses were driving me nuts; there was always a smudge on them from the rubber eyecup and I hated dirty glasses.

    I have extremely good Distance viewing and really poor closeup viewing. Because they were so diverse, I had problems finding an ideal contact. I went through a long testing period with many different brands of lenses (they are all slightly different) I finally found one brand that worked and wore it successfully for about 6 months. When I bought my second batch -- they no longer worked! I got a lot of headaches and things just weren't clear. My Doctor could never figure out why.

    So, she switched me to Mono vision. After a very short adjustment period, they worked well. But yes, they did affect my depth perception. I got used to it and knew how to compensate so I didn't really have an issue with it.

    Each year when I go for my annual checkup, my Doctor has me try whatever new contact may have come out on the market. Last year, I tried a new BiFocal contact that finally worked for me and switched away from the Mono Vision. The improvement is immense. The depth perception problem is gone and my sight is a lot better. I still get headaches if I try to use them for very heavy computer use but I think that would be the case no matter what.

    So, if you hate wearing the glasses as much as I did, be persistant. Every brand is slightly different and you may react differently to each one. Also, there are new contacts out on the Market all the time. Ask to keep trying. I now wear the contacts during the day, a pair of progressive BiFocals in the evening if I want to read, and a pair of straight reading glasses for reading a book or intense computer work.

    Hope this helps,

    Lin:smile:
     
  16. Can you guys type bigger?
    I can't read this tiny stuff :rolleyes:
     
  17. hahaha, one in every crowd. :)

    Getting old beats the alternative.

    I use several pairs of glasses. Weak reading glasses for computer, stronger for all that darned fine print, bifocals for driving and camera work, very slight strength with the auto-shading for golf. All are a PITA but necessary.
     
  18. Lin,

    Thanks for the advice. I will wait to see how I respond to the mono-vision setup for the contacts, but my guess is I will have an issue with depth perception. I actually like the progressive glasses that I have (some people have problems with them), but for some reason any smudge seems to be amplified with them.

    On the advice of my family, I went with a smaller frame for the glasses (I lost a lot of weight last year and my current frames seem large on me). Maybe that will help when using a camera. But if not, and if I am unsuccessful using contacts, there's always the option of going with a camera with a good eyepoint and eye relief (i.e. D2Hs, D2X) instead of the one I am waiting on (D200). Even with my current glasses, I have very little issue with the viewfinder of the D2 series.

    Hi Michael, my apologies, finally caught up with the topic. The mono-vision works well. No problems with depth perception or balance. I can see the top panel clearly, and the view through the diopter is uninterrupted. Changing to long distance vision is easy, and as expected even my atrophied brain has adjusted to the new inputs. For anybody who wants to use a camera in the rain, without glasses, etc I would recommend a trial with disposables. An optician will let you try for free. I still wear bi-focals 'normally', but if I'm going to be out playing David Bailey for an hour or so I switch over to the lenses. 30 pairs of disposables cost about £15.
     
  20. Rob,

    Thank you for the update. I think my desire is to wear contacts 'normally' and to wear the progressive glasses in the evening when home and not shooting. For me, wearing contacts not only would help in using a camera, but there isn't the rain issue associated with glasses, plus I wouldn't need to keep changing between my glasses and prescription sunglasses when driving or at outdoor events in the daylight.
