I’m going to need glasses and hearing aids in the next few years. I already use small magnification readers when text is small or my eyes are fatigued, and I know that my hearing has diminished. One example of my hearing issue is that when we shut down our gas fireplace it beeps, but I don’t hear the beep. That sound is no longer in the range that I can hear. I only know it’s there because my wife and daughter mentioned it.

It’s only in relatively recent history that we’ve had access to technologies that allow us to enhance our senses when they fall below ‘normal’ capabilities. Before that we just lived less vivid lives as our senses worsened.

Having my family ask me ‘Can’t you hear that?’ and listening to nothing but their voices, knowing full well that I’m missing something is a little disconcerting. How are they getting to experience a sound that is outside the range of my capability? But the reality is that there are sounds they too can’t hear, which dogs and other animals can.

This makes me wonder what our world really looks and sounds like? What are we incapable of sensing and hearing, and how does that alter our reality? And for that matter, how do we perceive the world differently not just from other species but from each other? We can agree that certain colours on a spectrum are red, green, and blue, but is my experience of blue the same as yours? If it was, wouldn’t we all have the same favourite colour?

A few years back I had an eye condition that affected my vision at the focal point of my left eye. Later, I accidentally discovered that this eye doesn’t distinguish the difference between some blues and greens, but only at the focal point. I learned this playing a silly bubble bursting game on my phone. Without playing this game I might not have realized the limitations of my vision, and would have been ignorantly blind to my limited vision.

That’s the thought of of the day for me, how are we ignorantly blind to the limitations of our senses? What are we missing that our world tries to share with us? How will technology aid us in seeing what can’t be seen? Hearing what we can’t usually hear? That is to say, that we haven’t already accomplished in detecting? Our houses have carbon monoxide detectors, and we have sensors for radiation that are used in different occupations. We have sensors that detect infrared light, and accurately measure temperature and humidity. This kind of sense enhancing technology isn’t new.

Still, while we have sensors and tools to detect these things for us, we can’t fully experience aspects of our world that are present but undetectable by our senses. It makes me wonder just how much of our world we don’t experience? We are blessed with amazing senses and we have some incredible tools to help us observe the world in greater detail, but what are we missing? What are we ignorantly (or should I say blissfully) unaware of?
