VR may cause vomiting – because of motion sickness

VR may cause vomiting – because of motion sickness – In order to fully enter the virtual reality,
one has to deceive not only the eyes but also the other senses.
This is also the reason why
many virtual reality users can cause problems with motion sickness.
Then the impressions
received by the liar do not agree with the visual stimulus.
In motion sickness,
the eyes see that the body is not moving, and that the labyrinth registers continuous motion,
tilting and acceleration, in the case of nausea caused by virtual reality is quite the opposite.

Eyes see the perfect simulation of space, covering the entire field of view.

However, the brain does not record any motion signals from the labyrinth or other senses.

In both cases there is a sensual dissonance that causes malaise, dizziness, fatigue,
and even vomiting.

Implants German scientists – Researchers at the University of Tübingen in Germany made a breakthrough discovery. Those who have lost their sight due to degenerative disease of the lens, it will be able to regain at least in part. The researchers performed a special implant after implantation which people will recognize shapes of objects or characters.

Eye evolution

Eye evolution

Eye evolution – We see the world around us through opsins – proteins containing photosensitive dyes, produced by the receptors of the retina. In humans and other animals with type chordates Branchiostoma lanceolatum, fish, amphibian, reptile or bird. The variety is known as copsin. Meanwhile, in arthropods and cephalopods so the spiders and octopuses. This is the function differently built r-opsin. So it looks as if nature created two different ways of development of sight, at a very early stage of evolution.

Photoreceptors in retina – Scientists have discovered that a little-known type of photoreceptor cells in the retina, the name on ipRGCs, plays an important role in distinguishing between darkness and light, which is crucial to the formation of images. The cells in the retina are divided into rods and cones. The human retina is 7 million cones and 130 million rods.

Fear has big eyes

Fear has big eyes – The researchers found that the expression of the eyes has a practical significance. With a wider opening of the eye increases the sensitivity of the pupils to light, so also increases the width of the field of view. Better vision helps locate potential risk.
