How to develop visual focus ability?

[LSD-Rumi]

When I try to look at things to investigate their real nature, I notice that my eyes keep flickering and I cannot go as deep with this flickering. Is there any specific practices to increase focus or does it develop naturally with meditation?

You can also of course, focus on something. If you haven’t yet, try going for a walk, and effortlessly (not be any force) pick something way off in the distance in from of you, and visually maintain focus on it. You’ll notice thoughts arising, sensations like the feet on the ground etc, and just continue return full attention to that thing in front of you off in the distance. Thoughts might arise about how you need more focus, or should have more focus, etc. In simply noticing these are thoughts, you’ll begin to experience a certain delightful shift.
