Each day just goes so fast 00:00:05
I turn around, it's past 00:00:27
You don't get time to hang a sign on me 00:00:31
Love me while you can 00:00:38
Love me while you can 00:00:45
A lifetime is so short 00:00:49
A new one can't be bought 00:00:57
But what you've got means such a lot to me 00:01:01
We've got all day long 00:01:08
The optical effects are an illusion of the sight. Each person perceives them in different ways. 00:01:15
The brain has been programmed to see these waves and expect to follow them. 00:01:32
Therefore, when the sight is removed, that effect occurs. 00:01:36
Surely you have seen this dress on the networks. 00:01:40
It has become very viral because not all people see the dress of the same color. 00:01:43
White and gold or black and blue? 00:01:47
The cones of your retina are the ones that allow the vision in colors and the responses of this multicolor dress. 00:01:50
Humans see objects of a certain color due to the particular functioning of their eye and the interpretation that the brain makes of the information that comes to them. 00:01:57
Therefore, those people who see it blue and black have high-functioning cones, while those who see it white and gold have less sensitive cones to light. 00:02:06
The origin of optical illusions can be in a physiological cause, such as a dazzle due to an intense luminous stimulus that leaves the luminous receptors of the retina saturated for a few moments, or on the contrary, it can be a cognitive phenomenon. 00:02:15
The image we see right now is a cognitive illusion. 00:02:32
These can be amigable, paradoxical and fictional deformations. 00:02:36
They can, in some ways, cause more visual confusion than others. 00:02:41
The brain seems to find it difficult to form an exact image of certain geometric figures. 00:02:46
As an example, this one. 00:02:51
Many animals deceive the sight of their enemies, including human hunters. 00:02:53
They are simply confused with the background. 00:02:58
Many animals camouflage themselves. 00:03:01
The colors of numerous insects, for example, hide them from the sight of predators. 00:03:04
The same thing happens with predators. 00:03:09
That's why almost all fish have a dark back, so that prey birds don't see them easily. 00:03:12
Some ingenious artists used the optical effects in their paintings. 00:03:19
