This world is not as we see thro
This world is not as we see through our lenses but somewhat different.
This exhibition on Beyond Human Vision is about one of the finest outcome of
evolution on earth a light sensing Organ " eye ". Magnified view of this
biological specimens, is no way different from others it is as crude as others
however it is the most finely tuned evolution in the world of living beings.
This light sensing organ can be compared with camera which preserves or
translates the falling light on to it to some sort of visual perceptionn. In the
case of the camera, visual perception is developed through dyes that are
activated by the light and which can later be developed into a picture. Otherway
in digital cameras, the light activates transistor-like pixels to store a
digital record of the light level falling on each pixel. But in living being
photochemical substances of the eyes activate special neurons that send signals
to the visual perception of neural network.
There are innumerous species which have eyes some are similar to human being few
are different, but each has its different capability and limits. We have some
predicament in our hind sight that species other than human being see the world
When we think about this, our heart feels expressing sympathy for the “poor”
species incapable to see the world as wonderfully as we human being can. Though
it is true that our visual acuity is admirable, there are animals that see
things that we cannot, or see the world in ways that we can only imagine.
The ability to see color works more or less the same for all living things. Each
color represents a different wavelength. When light hits an object, some
wavelengths are absorbed and others bounce back. This creates what we call
color. We human are trichromats meaning we have special cell in our eyes called
cone cells capable of detecting Red, blue and green, when stimulated, these
cells send signals to the brain, where they are interpreted into an image with
However, we will be amazed to find that some animals possess cones that are able
to detect ultraviolet wavelengths and other animals are able to detect infrared
wavelengths. Additionally, some birds have cones other than those previously
mentioned, meaning they can see colors we cannot.
Bees have cones for yellow, blue, and ultraviolet light. This means they see
wavelengths we cannot, in addition to blues and yellows and mixes of those two
colors. The UV information in particular guides them to the nectar they need, as
most flowers have patterns in the UV range that we can’t see.
Through this exhibition containing interactive exhibits and informative panels
we are unveiling the arcane which is beyond human vision.
