Sutegura [Visual Recovery Training]

While enjoying using stereoscopic images (stereogram)
Let's restore visual acuity training!

Stereoscopic images (stereograms) shift the focus of images, pictures, etc.
It seems to be three-dimensional by looking. As you can see at first
It is difficult to become, but as soon as you get used to it you will be able to do it.

[How to use]
(1) Please choose from silhouette · pattern · shape first.
(2) Please select the image you want to see next.
(3) As you move the viewing position while looking at the black 2 points at the top of the image, you will see 3 points.
At that time, the shape emerges in three dimensions.
* You can check the shape which appears by pressing "A" button.
