Palming is excellent for vision - and esp. for any retina problems (like detachment). Eyes are closed.
This palming method works great for me. Thank you for the much needed relief.
First let me say that neither my husband nor I wear glasses and we are in our sixties.
When we find our vision going out of focus we stop trying to read immediately. The worst thing you can do is try to force your eyes into focus. Then we palm (Bates Method for Improving Vision) We palm throughout the day. Once you palm for a few minutes, try reading the material again. You most likely will have brought your eyes back into focus. If you already wear glasses, palming frequently throughout the day will most likely help your vision.
What is palming? Cover your eyes with the palms of your hands formed in a cup to avoid pressure on your eyes. The objective is to make it as black as possible to allow your eyes to refocus (regain its point of central fixation).
This has certainly helped our eyes and it might be worth a try.
