Glad if it might have helped- I’m not sure if what I may throw out there triggers and assists at times…
<<now the only sensation I really get is similar to having your eyes open in a pool that has too much chlorine in it. Much better than invisible ‘needles’!>>
I can relate, I’d say that’s much better
Just to add a twist (in partic from Tao “water method” chi gung, but I find it runs in my ongoing, so like realizing one torques one’s back when sitting or leans, or raises a shoulder unconsciously… more an all the time, vs “when doing chi gung” as can be partitioned) : might add the idea of “receiving vision”
Not "pushing out" the eyes (nor "pulling in"- let the eyes wait and be ready to receive the light coming in.. I worked with that idea until I really got it, as sounds ok, sure, but underneath.. hmm what does that mean? realized the tension literally as if reaching out to go and get- in the literal eye ball.. in some people gets bug-eye look even). if not in the entire eye, but just parts can "dry out the eye" and feel left-lower part of eyeball pushing/tense (push part-pull other.. ugh).
Also imagine you have some clothes sort of scooped into your arms- like hugged to your chest (the tree hug sort of position) like forearms basket (not so much for that pose, just the metaphor, but the practice drawover may be revealing)…
Then imagine (or actually) let your arms open and let-go the clothing a bit- not fully- but open so it starts slipping the grip that was holding it… it sort of slides via the opening down your chest-stomach. to your seat (if seated, or hips-standing/same thing) and then the floor-feet… even if seated slips along legs…
If that same slipping through your grip- gravity (not release, but still in the grip- just enough: this came out more compicated- quick to show in example, but thought I'd struggle-force myself to try and type it out :) other example holding a staff (broom handle) in the middle of it... so one end is pointing at the ground but raised up.. loosen your fist a bit so it just starts to slide-fall down, not disconnect your grip fully, but not hold tight enough so it is stuck... you can find that you can loosen a lot before it starts to move anyway (and thus baseline holding is tighter than needs to be... same in neck-torso- and in "mind")
Thus have the awareness behind the eyes (not just physically- literally not as an idea /eye-de-ah… and not visualize… making picture to see/think = tenses eyeball and thus optic nerve tension [one can allow vision elements to float up into awareness without “creating” via tensing parts of experienced visual field)… .not just phy, but also in exper… and thus feeling/mind (just behind where you are sensing-looking from… let that part- release- and what is held within that grasp can slip a bit… to where it can go, more free? we’ll see…
that (as a part of qigong/neigung) a tweak to get, but do and can get a softening-moistening of the eyes in practice (and then as baseline… “eyes in pool” could also mean a feeling of floating, better than stuck-solid… but then more
=====
(see with your “feet” by your “feet- under the ground” looking through your "center which then sees what comes into your eyes (not looking “out” your eyes)… not imagine that part looking, check in and see if it is… if it was it would be… but the thoughts say if there is then I’ll take it over) If that feeling can click (over time and practice that changes meaning alot) could help- luck
