My glasses

My companion is my guide,
Without it I am a bat.
Wandering about confused.
They are adjustable and fickle,
They are my reliable glass eyes…
They accomodate to my daily tasks
And allow me to learn properly.
My eternal lamp lighting my path,
They are like hawks lending me their sight.
They create unpaintable drawings,
Some that are not real.
What is this artist called?
My trusty friend, my glasses.
