Optical illusions can come in any shape and in any form
Optical illusions can come in any shape and in any form. You might have optical illusions while going through a highway on a hot summer
day. This is the time you get to see a mirage. A mirage is an illusive
word which might elude you for a long time; you might run after it but
is actually not there. The reason is pretty simple- it is a mirage and
it is bound to disappear. Again and again it might appear in front of
the eyes. Mirages are a form of optical illusions and it is one of the
most common forms of optical illusion which is visible in front of us. A
mirage is just a figment of our sensory imaginations which develop due
to successive reflections of light. Usually in the summer days light
from a distant place seems to be just in front of us due to the
successive refractions of light at various layers of the earth’s
atmosphere. When the light rays reach us it brings to us the images of
the water bodies which are at a distance to us. Hence such images bring
reality in front of our eyes but are they genuine? The answer is
obviously no, since such images are nothing but just an optical
aberration. This is a common phenomenon of the deserts and it is
commonly an idea of travelers that a water body is present very nearby.
Hence one can regard mirage as one of the most commonly found optical
aberrations.
 The red dot and the curved lines can be used as an example to explain
many optical illusions. Our mind is constantly being loaded with new
information and this information is constantly being registered in the
brain. Some kind of advanced programming goes inside the brain to
process these images. If you see a number of curved lines along with a
red dot in the middle you are bound to notice them turn backwards. This
is obviously due to the brain’s advanced response system. This response
system filters out many things which are being repeated and in the same
process it straightaway sees the curves turn right. The turning right of
the bent curves imply that this filtering system is entirely based on
the programming of our brain with respect to scanning images. This is a
simple example but there are a host of such optical illusions which
would be completely based on the brain’s inability to perceive things
properly.
Hypnosis is a state of mind where the mind is fixated into a state of
trance. Hypnotic optical illusions can be brought about in individuals
who are under the influence of hypnosis. In this state the mind and body
goes into a complete state of trance which would force them to visualize
strange figures and perceptions. This is called hypnotic optical
illusions. Hypnotic optical illusions would yield results which would be
very startling and would go beyond explanation by any form of human
expression. Hypnotic illusions are created I the mind and are completely
lost after the hypnotic spell is broken. The person finds it difficult
to recollect the things they saw during the hypnotic procedure. When
objects are spun at high speeds at the front of a human eye; special
effects are created which would help in generating a process of
hypnosis. Special visuals would be created by this effect and spinning
object optical illusion is a very common affair. Any rigid object
spinning at high speeds would be a complete source of illusions since
our vision would not be able to persist with a single frame for such a
long period of time. This is one reason as to why we have optical
illusions.
