At least they could have made one that isn't shaped like sports glasses, so it could easily fit over glasses. I saw those before, glasses with small holes. It helps you see they said. I don't know though.

Pulfrich effect and only works with motion pictures.

He does not even know how it works.

The Pulrich glasses are not colored.

The effect is generated by difference in light intensity received by left and right eyes.

The holes in lenses act just like neutral density filter reducing

the light cumming to both eyes in different amount depending on eye convergence point.


I have made the same lenses and tested with static and motion images. There is zero depth when viewing static

and plenty of depth when viewing motion images.

The depth is randomly correct or reversed.


To get the same effect use regular sunglasses and just remove one lens.


Paper Pulfrich glasses can be purchased at:

"Aren't these just pinhole glasses?


Answer: No. TV Eyes 3D glasses are not pinhole glasses.

They resemble pinhole glasses, but if it was possible to watch TV in 3D with pinhole glasses we would have been doing it for decades by now.


The TV Eyes 3D effect is a marginal effect that only exists within a very small range of tolerances.


It requires an exact ratio of distances between the holes, the wearer's eyes, and the distance to the TV. Sort of like how a bike will only stay upright within a narrow range of angles and speeds.


Change the angle and you have to change the speed, change the speed and you have to change the angle. Yet most people learn to ride bicycles.


TV Eyes 3D glasses are designed specifically for TV viewing and to allow each viewer to adjust the glasses to the correct range and angle for viewing in 3D, pinhole glasses are not."

Total crab. The only requirement is motion images.

It's possible, seeing as the lenses are curved slightly.

That the light enters the same holes on either eye, and depending on the distance the glasses are from the TV the light exits the holes at different angles.


If it did this then the eyes might try and converge, and so have a sense of 3D.


With regular pin hole glasses the holes are so close that when they exit the holes they blur into each others light beams, but with these novelty glasses the light beams don't touch when they exit the holes so they stay on their unique angle.


Another way to do this would be to have a sensor in the glasses and when you wear it somehow you could be told to move farther or closer so the light leaves the glasses at the intended distance for the 3D effect from converging the eyes.

The glasses in question:






Pulfrich glasses:





I could be wrong, but they appear to my untrained eye to be different glasses.

Yes,

but the only stereoscopic image one gets with both is due to Pulfrich effect.

So you are saying that the website is lying and misrepresenting their product?

Just not telling how it woks.

If they would admit is Pulfrich then no one would buy it

since Pulfrich glasses can be purchased for US$ 1.00

Have you been posting without reading? They specifically state it is NOT Pulfrich in their FAQ. Here is the link again, this time with red highlight..

No. These are a different kind of 3D glasses and create a different kind of 3D effect. TV Eyes 3D does not use different color lenses or rely upon direction of motion or delayed stereopsis.

They may claim that it is not Pulfrich.

But they do not provide any theories that would explain how it works, if it works.

And since I have tested it and only effect that I see it is Pulfrich then it is not possible that there is a subtle 3D effect that I did not notice but everyone else has.


Again, not telling how it works and dismissing Pulfrich

is a convenient way to sell Pulfrich at 24 x higher price.

No,

all I've said was that they are not telling how it works.

There is a difference between lying and not telling how it works due to lack of such knowledge. And saying that is not Pulfrich becasue of lack of stereoscopic vision knowledge is also not qualified as lying.

It is just convenient to play ignorant.

It is only my suspicion that it is possible that some one has

pointed out it is Pulfrich and they do not want to admit it for obvious reason.

So, conveniently playing ignorant equates to not lying. Well, I'm glad we cleared that up.
