3D contact lenses?

3D contact lenses?
No joke: polarisation filters onto your eyes.

Televisions.com reported today on news that 3D contact lenses are soon to hit the market.
But what impact can we expect this to have on the 3D viewing experience? Surely once the filters are actually in contact with the viewers' eyes, the difference between 3D movies and normal vision must begin to blur if you'll excuse the pun!

It seems almost certain, from what we know, that the lenses will use circular polarisation to separate the left and right images. The shutter-glasses technique, planned for the first wave of 3D TVs later this year, requires a power supply and therefore can't be accommodated in such a small lens.

For anyone who's tried shutter glasses before, which technology do you prefer? And do you think contact lenses could be the missing link in making 3D movies a more comfortable viewing experience?

April 1st is still a couple of months away guys ;-) This can't actually be serious for a whole lot of reasons, mainly how do you alternate two images with different polarization on an LCD or plasma screen, and who will really take the trouble and expense to buy and wear new contact lenses just for an occasional 3D viewing?

Unbelievable fail! Somebody is reaching at this point.

WTF? I can barely stand the glasses.

Hi Fussy viewer,

actually it is serious. It's unbelievable, but these products will hit the market.
It is circular polarisation, so you can turn your head and it works for LCD monitors with polarisation filters (line by line) as well as for polarized procjetions with silver screens.
I'm not convinced either, but that's the reason of starting a discussion about it here.

Is there anybody in this forum who could imagine to use 3D contact lenses instead of glasses?

Cheers,

Florian

I already wear contacts, would I have to get prescription 3D lenses? I guess I'm stuck using glasses.

3D contacts = Infinite headaches (for me at least)

Imagine IMAX on your brain.

Here are my preferences, from worst to best:

(1) 3D glasses + my glasses
(2) 3D glasses + my contacts
(3) 3D prescription contacts
(4) 3D prescription glasses

I am willing to switch (3) and (4) if 3D contacts provides vastly superior 3D picture quality over 3D prescription glasses. But it is inconvenient having to put on the contacts before the show, and take it off after.

Awesome. I wear contacts now and this would be preferred over wearing glasses everytime to watch 3D, especially if/when I get it in my home.

Circular polarized contacts will not impede normal vision all that much. The only difference will be a slight "sunglass" effect, so seeing in dark places will be a little more difficult, while bright sunlight will actually be MORE comfortable. Replacing your prescription contacts with Circular Polarized contacts will basically be just like wearing normal contacts, and have the added benefit of 3-D capability when looking at a circular polarized source. Thus, there is no need to swap your contacts just before and just after the movie.

I am all for the idea, and may switch to contacts just for this purpose.

Nice but for now none of the 3D tv stuff coming is using circular polarization. For now its exclusively used in "RealD" theaters.

Hi abr27440,
thanks for your comment. What you say is generally right for now, but circular polarization will reach consumer products.
If you want to know more about it, please read our news about LG 3D.

I'd much rather have contacts to wear than glasses.

As a long-time contact wearer, I say bring it on! I understand that most folks who aren't used to putting things in their eyes will probably be repulsed by it though.

3D contact lenses could be a cool thing for hard core gamers already wearing contact

This is a good point!!! I wear contacts, I can't imagine this working unless the person had perfect vision..........which most people don't. If you are reading threads on AVSFORUM all day, I can all but assure you nobody does if they are past 25 years of age..........lol

I can't imagine how this could possibly work. You wear the 3D contacts for watching movie then what do you do after the movie? You can't really walk around with them, can you? So you need to take them off, wash, rinse, disinfect, then put your normal contacts or glasses on? What a hassle.
post #18 of 38
I do not think I would like to use those contacts. The glasses are sometimes bad enough for my eyes!

As someone who has worn contacts I can say that it takes weeks to really get used to the feeling of them in your eyes, not to mention to be able to put them in and take them out easily.

It depends if the contacts are hard or soft

What has the world come to!

3D glasses and contact lenses are simply polarized plastic the same as sunglasses. The only difference is the angle of polarization is misaligned to make them 3D. Wearing 3D glasses or contacts in unpolarized light should be no different to wearing polarized sunglasses. The only time it would be a problem is when you are viewing a polarized image (lcd displays). But thats the same for polarized sunglasses already.

Surely not! The glasses gave me a migraine when I watched Avatar, I can only imagine what these would do to me...
post #24 of 38
Those that have undergone Lasik corrective surgery are out of this. I was warned prior to my Lasik that I would never again be able to safely use contact lenses.

Lasik surgery has been one of the best things that I ever chose.

Due primarily to age, I found it increasingly difficult to wear contacts several years ago because I'm somewhat nearsighted, and while contacts allowed me to see distance well, I actually had to wear reading glasses to use my computer or read a newspaper with them in. It became far more convenient just to wear glasses when needed.

As such, now I need to wear the polarized glasses over my regular glasses when watching 3D movies such as Avatar, and I find that detracts significantly from the movie. What I would like to see is a polarizing film to apply to your regular glasses for watching such movies, or perhaps clip ons (like sunglasses). It would make it much more comfortable for us older (HA!) folks... you know, early 50's...

For that matter, if they can make contact lenses for vision correction, why can't they make contact film for application to sunglasses to do the same? It would sure be more convenient than purchasing prescription sunglasses and probably much cheaper... but that's a different topic.

Nice idea, ill wait and see. Maybe we will get a pill for 3D one day
post #27 of 38
Please tell me how one would attempt to calibrate a 3D display with the user employing the new 3D contact lenses when they are available.? you would need to place the lens between the color analyzer and the display screen to be measured as the lens polarization greatly effects the calibration regarding both brightness and color.
post #28 of 38
As a retired optician, this may be quite doable. The potential problems would be that the lenses would have to be weighted on the bottom to allow a correct polarization plane. This already incorporated in soft "toric" lenses that correct for astigmatism.

They work well, if they fit properly. A poor fit allows the lens to rotate or shift when the patient, (whoops) 3-D user blinks.

Alas, my eyes dried out long ago and had to switch back to multifocal spectacles.

I cant see 3D contacts replacing 3D glasses. No way they'll be cheaper and throwing on some glasses is way easier than sticking some contacts in your eyes

Just make the darn TVs 3D and let's call it a night.
"Obe wan, you are our only hope" if you know what I mean. That's the only way..
