Iridescence

I can see that I am going to be learning something new every day about eyesight and perception.  And maybe more importantly - I CAN SEE!

I have always had monovision - didn't know it was a thing or that it had a name.  It means that all my life one eye has specialised in near vision and the other distance.  Not at all uncommon.  And it worked pretty well for me, didn't need glasses until I was in my sixties.

In November close vision and colour perception were restored to my right eye with a close vision lens.  As the lovely surgeon said at the time 'Your right eye will be rubbish at distance.  Be careful.'   He was right!  It's been a vivid but dodgy few months.   Yesterday he fitted a distance lens to my left eye restoring monovision so my eyes can co-operate again to create a 3-D world in full living colour.  Wow!!

I learned a lot of things today.  Stereo colour is astonishing.  BUT/and you need depth perception to perceive iridescence.  I've been living in a kind of 2-dimensional visual world for the last couple of years.  

Suddenly today, with both eyes working together again, I can see depth and distance and colour and shape and dimensions and, and, and ...

Small wonder i have not felt drawn to make images, I couldn't see them.
Without depth perception you cannot see iridescence.  What a thing to discover.
