I have eyesight on my 2016 legacy limited 2.5 and I had my OEM windshield cracked so safelite replaced it with a pilkington ez kool plus windshield. I called my local subaru's service department and they said that no calibration is necessary. Since the replacement, my eyesight has been working as expected (it even engaged the pre-collision braking for me once because I was careless, whoops). Also I've had success with the other features that eyesight has provided: lane keep assist, adaptive cruise control.
