Strange to think,
How we used to blink and grope our way
Through the blurry day,
Our vision out-of-sync.
Ever since the needle was invented,
How the squinters were tormented
Without sharpness to apply
The thread into the eye.
But then, and just in time for printing,
Came the perfect cure for squinting –
All was focused once again,
From furthest hills to finest grain.
Of all our labour-saving friends,
I say the lens is friendliest of all –
It works so simple, cheap and small –
Such humble, perfect skill !
And yet so mighty, how it bends
All light unto its will !
To let us see, when genes and wear
Would waste our rods and blank our stare –
