A little more information.
It’s like, instead of looking out of the eyes*, the scene merely comes in as a whole. One isn’t looking for, or at, anything: there is just seeing, and the seeing is not held onto. Everything becomes brighter.
The eyes are merely a surface upon which images rest. This connects directly to the mind, and the mind is still. Then, awareness can either be aware of being aware, and therefore stay in relative reality, or completely let go, realising the empty quality – absolute reality.
We can notice that we can oscillate between these two states. One is holding on, and the other is completely letting be.
Best is short moments many times, as it so easy to get caught, holding on. So, see drop, see drop, see drop. Gradually, those moment join up!
* it’s the same with all the senses.
BUDDHA IN THE MUD is a blog - a living book based on the Dzogchen teachings. Our teacher is life, and life is karma. We are all Buddhas in the mud of concepts. 
Oh, I like that…”The eyes are merely a surface upon which images rest”.
And of course, “short moments, many times”. Allowing self-existing wakefulness just to remain. Without alteration, without distraction, and through repetition, we will become more familiar with that.
