Speaking only very generally (because everyone ages differently): when you're an active player anywhere on the spectrum between early senior years and well into your 70s, even 80s (I'm 83) it's crucial to studiously tune up certain key things periodically via very self-observant special practice sessions, as follows (and they needn't be long sessions):
(a) Carefully notice and allow for the fact that retinal and lens acuity (and aging eye muscles) and the muscles involved in your stance and setup can change in subtle -- or sometimes major -- ways from your younger days and therefore affect where your optimal vision center and head position should be. Experiment with changes that help your accuracy and CB position play.
(b) Ensure that the timing of your eye movements between CB and OB is ideally coordinated to what your arm is doing during each of the phases of the aiming and stroking processes. Subtle, overly-casual lack of concern about this important eye-movement timing often creeps in amongst senior players and can make a huge difference in performance results.
The (a) and (b) items I cite above can be consciously monitored and ingrained during these recommended periodic tune-ups from year to year in the special practice sessions by being deliberately observant and not least, by definitely recording those sessions using a mounted smartphone or camcorder. The camera is an objective observer -- virtually a coach that will notice physical and behavioral things that you couldn't spot yourself. The recording will then "report" them to you when you carefully study the video. You'll then see any easily correctable performing lapses you can either remedy or work around by making a few changes that make up for physical body aging of strength and endurance, or overly-relaxed attention to the details that once were automatically present in your game . . . and thankfully can be regularly made automatic once again when you're consciously aware of year-over-year needed adjustments.
