Difference in light perceived between right and left eye

Hi,

I noticed something strange while watching TV in the dark last night.
I had the channel guide on, and noticed that my right eye sees things
brighter than my left. Not a huge difference but definitely a
difference, like bold text vs normal text.

The eye that sees things 'darker', my left eye, is also faster to
adjust to bright light, like walking out of a movie theatre into the
sunshine.

Is this condition widespread ? Or am I bonkers ?
