Philco had a line of color sets in the late '60s with a tuning eye. I don't recall the model number, but the set was a console that had a horizontal eye tube. When the two segments just met each other without overlapping, the fine tuning was set for the best possible picture.
You are probably right as far as AFT (automatic fine tuning) is concerned. This system took the guesswork out of tuning a color set for the best picture; with AFT, of course, there was no further need for tuning eyes or meters (the latter used on some late-'60s models of GE color TVs). The advent of quartz-locked electronic tuning meant that all the viewer had to do was select the channel and forget it. Today's flat-screen TVs probably use this type of tuner; in fact, it wouldn't surprise me if they did, since there is no AFC switch on these sets.
