Human eyes are subjected to daily loads. Excessive overexertion can cause the development of ophthalmic diseases. To relax the muscles, you can use stereo images to improve vision.

Human vision is normally binocular. Thanks to this, the eyes can see a three-dimensional object in a flat picture. Stereograms are used to train this ability, as well as to maintain and increase visual acuity.

Stereo pictures are a flat image of repeating patterns of dots, geometric shapes and other objects on a certain background, in which a 3-D illustration is encrypted. The resulting stereo effect from viewing the drawing is based on the binocularity of the human visual system. The right and left eyes see the same object from different angles, and then combine it into a single three-dimensional image. The same happens when viewing stereo pictures. When closely observing it, there is a deception of vision and you can see a clear object in the visual chaos of small flat details.
