It is something I’ve been doing for a few days and it feels efficient so I thought it was worth sharing.
Usually I relax in a sofa while doing active focus on my Snellen. Lately once I hold a good AF I maintain it for as long as possible obviously but then instead of eventually blinking and see blurry again I close my eyes and keep them shut for a 20 sec. It feels like the ciliary muscles stay relaxed under my eyelids. When I reopen it is still in focus or if not really easy to reach back. And I do that again and again. It feels good in a meditating way and in a deceiving way as it is like the blur is gone for good.
I highly recommend this trick but if you guys are already doing that regularly then I apologize for wasting your close up time on this post.
