The balls are not where they appear to be
I started back playing a half dozen years ago after 25 years off, right after detached retina surgery, partly because i couldn't do anything else for however many months. Then it took a few years to figure out why i hit the balls so badly. (balls are not where they appear to be) Old skills would carry me along, then lay off a week, and it was like i never hit a ball accurately before in my life.
May have to explore some of the glasses options mentioned here, but one thing that finally dawned on me is that if i play more than twice/wk, my brain adjusts and compensates. If once a week or less, my brain does not automatically compensate and the frustration comes back. this is different from actual "staying in practice". It's what my eye-brain adapts to coordinate to the point it become unconscious, but seems to drop quickly again.
There have been several studies starting with George Stratton, that outfitted test subjects with "upside down" or other goggles that displaced a normal image. After a few days, the subject starts seeing things correctly again. When the goggles are removed, it can take a few days for the subject to see normally again.
Or at least that's my excuse for "can't hit a ball". :wink:
