POSTCARD #14: Rutnin Eye Hospital, Bangkok: I just had eye surgery for cataracts and there’s a protective eye shield with cotton wadding taped over my right eye, but I don’t remember anything about it. I remember lying on a gurney in the operating room, and recall chatting with the anesthetist as he’s putting the needle in my arm – then suddenly I’m back in my hospital room with the eye shield taped over the eye and no memory of it at all. I feel normal, the only difference is I know that a newer version of part of the eye mechanism has just been installed; I’ve had an upgrade. But the eye has to stay covered today, so I can’t see anything, except when the nurses take off the shield every hour and I get a brief glimpse; they give me eye-drops then it’s covered again. A great flood of liquid in the eye, slight taste in the mouth as it drains through the tear duct into the back of the throat; swallowing my tears, gulp, gulp…

They take the eye shield off next morning. I get dressed, go downstairs to the outpatients department and through to the exit. The décor in the waiting area is in shades of lime green and ice blue, colours are amazing. Unexpected. There’s a completely clear perception of distance for the first time in many years. Fascinating. I’m distracted by colour and movement at the edge of vision, face turns in that direction, curiosity – an involuntary response. Head spinning like a child or a small animal, noticing all kinds of things. Sense organs filter incoming information. In my case, visual data enters through implanted intraocular lenses (IOLs). I see the world and assume it exists exactly as I perceive it, but I know the lens implant has, to some extent, created my version of the world; perception is subjective, reality is a construct in the mind. I can see a wide range of colours where insects see ultraviolet, reptiles see infrared, and cats and dogs see the world in only two colours. Viewed in this way, the world is suddenly endowed with great mystery; ask the question: ‘what is reality?’ and it takes you to a different place entirely.

Out of the exit, wait for a taxi, on to the highway system and step into a world that looks like it’s been Photo-shopped, high resolution, multi-pixel display. If there comes a time in the future when I’m no longer able to see it in this way because the novelty of it has gone and consciousness doesn’t regard it as special anymore, then I can return here, read this post and remember how wonderful it was…

‘Normally we human beings assume the world ‘out there’ exists just as we perceive it (by way of eye, ear, nose, tongue and physical contact) but if we consider these sense organs, it must become apparent to us that the world ‘out there’ is really dependent on our particular modes of perception. For instance, the human eye limits conditions, by its very structure, the objects we see. It is well known that a bee can see, as a colour, ultraviolet but we have no idea what such a colour looks like nor, of course, can we find any words to describe it. It follows therefore that our sense organs being differently constructed from that of a bee (or any other non-human being), our world “out there” is not necessarily the world as it really is.’ [Phra Khantipalo, ‘Buddhism Explained’ 1965]

Note: Claude Monet had treatment for cataracts that left him with poor vision. He agreed at age 82 to have the lens of his left eye completely removed. Light could now stream through the opening unimpeded and he began to see – and to paint – in ultraviolet (Water Lilies series). [Link]
