Contact Glasses ?

Hi Friends,
Does any of you experience in using contact lenses instead of wearing glasses for picture taking ?

If I just could introduce again my eye into the vewfinder pipe, this would change a lot for me.

Two co-workers don't stop chanting praises for the contacts advantages, but i don't know if this may work (provided the correct 'dioptric") for rf cameras using.

:eek: :bang:

Cheers,
Ruben
 
In general, my eye sight is better with glasses than it is with my contact. That said, I also believe generally the opposite is true (that is what my dr told me). I do pop in my contact though when I am going out to shoot. Often though, if I am bopping around just casually shooting, I will go without my glasses and use a diopter on the eyepiece.
 
They're OK for some (most?) people, difficult for some and impossible for others.

I'm in the last category - I just cannot get them in. After three hours at the opticians he told me I should stick to glasses.

Can you get a free trial?
 
some prescriptions are harder to adress with contacts. By the same token, however, some vision problems are not addressable by diopters (like astigmatism). I would think contact lenses would be worth trying. You can usually get a set to try for free or a nominal fee. If you don't like them, you aren't out a whole lot, but you just may discover you really like being able to see clearly without having to wear glasses.
 
'visiondr' should jump in here ... he gave me some good advice on this forum a while ago about contacts! :)
 
My vision has always been better with contacts. As I've gotten older, I wear my glasses more often, but when I got out to shoot, I like to have contacts in. Not only do I see better, but I see more of the viewfinder since my eye is closer to it.
 
I primarily wear contacts, but I also wear glasses. For me, contacts are vastly preferable to glasses for photography. They allow full peripheral vision, they are not subject to glare, they don't get dirty, they don't get scratched, and they allow you to make full use of the viewfinders in cameras...particularly with rangefinders. Frankly, I would wear glasses a lot more if I was not a photographer.
 
I recently switched to contacts that you can wear 24/7. Even when sleeping. Gotta change them every 3-4 weeks. I like them very much, not least for the ability to use viewfinders properly. I even see better with them. Except when I'm really tired (now) and in dusty, dry environments with small paper particles flying around (at job, rotten cleaning there). I would recommend contacts... If you are able to get accustomed to the idea of not blinking while poking your eyes with your fingers... :rolleyes: It did take me a while, but eventualy got better at it.

Hi Kully,
could you detail your specific reason ? You say "I just cannot get them in". Do you mean a kind of "ergonimic" issue in the shape fitting of the contacts and your eyes ?

Am I correct in assuming upon your quoted post that the problem is not in the optics ?

Thanks,
Ruben

Hi Posti,
My co-workers mentioned too these kind of price cheap disposable contacts. They told me this kind is softer than the permanent ones.

Do you go to the optician each month or can buy 12 sets for a full year ? Is there any kind of drops (perhaps just water) to apply to your wearing contacts eyes when you are in a dusty environment ?

Thanks,
Ruben

Thanks Rover ! That was my basic question, contacts and camera viewfinder. I have two types of frame glasses and both types bi-focal. Originally when I ordered them I was perfectly covering from infinity to 0.2 meter. This second bifocal gave me sharpnes for computer distance and at the lower part for very close distance (~0.2 m) . Now my sight went to a point when this glass in its upper part gives me "critical focus" at 1 or 1.5 meter, but perfect harmony with most or all camera viewfinders. So I think this is the critical focus distance I should check with my optician for the contacts. This is the most important for me, eye inside the viewfinder !

Cheers,
Ruben

After a trial period during which you and the optician confirm that the lenses fit your eyes correctly and without serious trouble (like an eye inflammation/infection), they will place an order for say six pairs of the chosen lenses... Then you use them up and repeat the process. I think you'd be best off buying the first set from the optician just so that you get the correct type of lens. After that you can order them off a web site that sells lenses, if you wish.

I don't use any moisturisers. My eyes get better as soon as I get out of the bad air inside. But I can say this: Moisturising your eyes with water while wearing contacts would be unwise. This comes from the risk of introducing very harmful amoebae to your contacts. Once they make home on them, it is a serious risk for your eyes. So only sterile liquids into those eyes! :eek:

Oh, and you cannot wear contacts when you're down with the flue...so don't ditch those glasses just yet! :cool:

Don't bifocal contacts put different prescriptions in each eye to accomodate full vision? That might be a pain; you'd have to remember which eye was close and which was far and switch off in the viewfinder.
 
Ruben, no it's not the ergonomics.

Unfortunately I cannot convince my brain to keep my eyes open when it notices a finger heading their way with a bit of plastic on the end.
 
Kully

Does the other eye shut when a finder approaches it?

P.S. I still have not done any bulk loading exp for you, sorry
 
Some people's eyes are more sensitive than others. Soft contacts tend to be more comfortable, but they are still foreign objects in your eyes. Some people can never get over this. Most people's eyes adjust and soon you no longer notice you are wearing them.

As for drops, yes, I use eye drops in the morning before I put my contacts in, and in the evening after I take them out. I find that it helps keep my eyes feeling good, but it is not totally necessary. Sometimes drops are useful to keep the contacts from becoming too dry.

In any case, you might as well just talk to you opthamtrist about trying contacts out. I am not sure if they are easy for adults to adjust to. I started wearing them when I was 11 or 12, so I am not sure if it would be harder to adjust to them later in life.
 
Ruben,

I had a good experience with contacts and camera use... much better than with glasses. Unfortunately I had to stop wearing contacts and I'm back to glasses. It is much less convenient, as you seem to know.

What is your current prescription like? You might run into issues if you have a large amount of astigmatism (that requires toric contacts which are expensive and sometimes shift out of position more noticably than regular contacts) or need a bifocal solution.

The most expenmsive part of investigating this option might be the eye exam. If you are needing this anyway, have your optomitrist/opthamologist write two prescriptions: one for glasses and another for contacts. The additional measurements required for contacts will probably increase the cost of the check-up, but will let you know if you are really a candidate for contacts.

Best of luck in whatever you choose to do!
 
Ok, I buy.

My last question is what should I tell to my optometrist, as he doesn't understand about rangefinders.

a) I am going to try it for the exclusive sake of the viewfinder viewing. Later I may change my feeling and buy for general use.

b) My eyes problem is simple ageing. My vision is blurred from infinity to zero, gradually growing as the subject is closer to me. It started some 10 years ago.

c) With frame glasses set to infinity I don't see sharp at rf viewfinders. With rf viewfinders, I see sharper, as I said, with frame glasses designed for short distance ~1 meter. Perhaps any of you understand this phenomena.

d) Should I therefore tell the optometrist dignose me contacts with critical focus for 1 meter ? (I repeat, I will be going for the sake of the viewfinder viewing)

Dear Friends, You and not the optometrist are the ones to answer this. You must take for granted the optometrist has no idea about the rangefinder optic mechanism.

Thanks,
Ruben
