Optical illusion of a different kind- hollow face optical illusion
Hollow face masks are pretty common and many of you might have seen
hollow faced masks. Such hollow masks are a real life example of optical
illusion. Get hold of a hollow faced mask or else get hold of a colored
one. It hardly makes any difference since the hollow mask without any
color would create the same optical illusions as that of the colored
ones. Hence the most important subject of attention would be the optical
illusory effects rather than the object which is creating it. This is a
particular example of optical illusion which is most prevalent in
detailed objects having a 3 dimensional look. The 3-D looking objects
have a 2-D shape since the comparison of the dimension would make
breadth completely insignificant. Hence this illusory effect is created
in front of our eyes.
There are various ways to observe this since the hollow face would
 represent various images in front of the reader’s eyes. One should consider a particular frame or axis along which it would be completely
rotated and the rotation would yield an effect which would be completely
illusory. Just like a tennis ball would fox a person, once it is
completely spun at high speeds; a hollow mask would do the same. It
would fox a normal eye in a big way. The perception would be equally
strange since the hollow mask would give the impression of a two sided
mask. This might sound strange but this is true since any visual affect
created with this effect would yield such beautiful illusions. This
might also be a bit frightening for some people since such illusions
create doubts in the mind.
The light source plays another important role in this aspect. Light
sources determine the type of illusions we would perceive and the
position of the light source is very vital. The position of the light
source would determine the exact nature of the illusion which would be
visible in front of us. The exact illusions differ in most cases and in
this case it is just the light source and our visual angles which are
making all the difference. The difference is marked and at a distance it
is really difficult to distinguish between a hollow face and a full
torso. It would be very difficult to make out since the virtually 2-D
object is giving the expression of a completely 3 dimensional effect.
Various interpretations would suggest that the mask is hollow; others
would disagree at the first appearance. They would suggest the mask is
full; hence it would be completely skeptical to analyze things from a
distance.
 Other examples of illusions include those which involve top views and
front views. Architectural concepts have been derived from such
conceptions since the top view; side view, vertical view and horizontal
views are all optical illusions. Optical illusions would result in
various innovative concepts ad designs and it may sound strange but this
very concept of optical illusions has been utilized by many designers.
Such designers have completely revolutionized the way in which we
conceptualize style. Hence we can find one aspect of designing which can
be associated with optical illusions. . The color changes are used as
the tools for bringing about the special effects. Special effects are
not effective if they cannot use the subtle movements of the eye, hence
this is purely an optical phenomenon. The term fiction is being used
since the optical illusions can never be realized physically; it is just
a property of light and our eyes too. It is a virtual reality where
things seem to be real but in reality they do not exist at all.
