We see the world quite differently from the way humans do. For a start we are so much smaller. Looking at a hedgerow of long grass and foliage We look at it straight into it (above). So much better for spotting small rodents! Humans look down on it from their great height (see below)
We don't see so much colour. That's because we have far fewer colour-perceiving cells, called cones, in our eyes, than humans do. We can just about see the same three primary colours but only dimly.
And everything we see is blurry compared with human sight. These photos don't show that due to human error! Blurriness is partly because the colours are dim but also because we have traded sharp sight during the day for good sight during the night.
We see in the dark much better than humans do because we have far more light-receiving cells, called rods, in our eyes. We also have bigger curved eyes and bigger pupils than humans. (Please don't go about poking us in the eye to measure it.)
And our eyes glow at night.. because we have a mirror-like tapetum which reflects back the light into the rods, meaning that more light reaches them, though blurry.
That's where we are superior. OK so we can't read The Times but why would we? We can catch mice when they come out in the twilight. Humans can't do that.
Knowing someone as special as you adds a little extra joy to the day. Wishing you sunshine and a basket full of chocolate on this beautiful day. Happy Easter!
