Do You See The Same Colour Differently?

3 min read

It’s possible your eyes perceive same colour differently. Ever noticed that why a particular spot on the wall appears slightly blue when you look at it with both eyes open however closing one would turn it into a shade of red.

This is a unique situation and not particular some eye disease. Perhaps one of the most fascinating thing is that the condition is quite common among the most but still under-research. Although no serious impact is laid on the eyes, those who have this strange condition usually ask ‘why they see same colour differently’! Let’s have a detailed look.

Our Observation on Colours

The human eye is constantly being researched upon which makes it quite evolved and complex. One thing which makes it better and unique is its colour perception factor. From the way we decorate our home to how we dress and define our lifestyle, everything’s influenced the way our eyes perceive.

Part of the eye which let us know of the colour is the retina; the light sensitive part of the eye which is made of photoreceptors known as rods and cones. Within the retina, there’re over six million and three different types of cones in the eye that can detect the red, green and blue. Recall the RGB in computers which pretty much clarify things.

Then there’re monochromatic rods in the retina that dim and adjust brightness whereby important to interpret light and can only perceive the shades; not the actual colour. But then, how colour reaches the receptor? If light is absent, a human eye’s unable to perceive colour which means the light has to bounce from an object and into the eye which is refracted to the retina through the cornea which functions the cones and rods.

The ‘ganglion cells’; neurons inside the retina then process the visual data from the cones and define colours the way we see them. The colour signals are further broken into three colour groups namely green/red, blue/yellow and brightness before being redirected to the brain.

With such a precise natural process, even the slightest difference in a single eye can change the shades as we see them. On the contrary, not both our eyes are always identical, either by birth or perhaps an anomaly which causes the phenomenon. People at times mistake asymmetrical eyes to colour blindness so let’s also clarify this particular fact as well.

Colour Blindness

A condition which impedes an individual from distinguishing between colours and not the disability to see them at all is referred to as colour blindness. Instead, people have trouble making it out between shades of pink, red, brown, burgundy so on. Colour blindness occurs when something’s misaligned or askew with the retinal cones or maybe the cells are absent or non-functional. That said, cells may be functional but only for the colours a person’s able to perceive.

Colour blindness can be mild in severity which means the cones are functional but detecting unusual shades. It’s possible that one might’ve gone through an eye surgery but experiencing a backlash to the procedure. Always consult with the doctor and there’s a possibility you might be recommended a YAG laser eye surgery procedure in case the reaction is because of the previously performed surgery.
