Fig. 4 Rankings from the three preference questions.
Rankings from the three preference questions. Each black dot represents a user ranking. (Left) The users’ own corrections are more physically comfortable, even with only a short period of wear. Some prefer autofocals, citing lack of a need to crane their necks back. (Middle) On the other hand, the ease of refocus question shows a clear preference for autofocals, especially over the depth-tracked mode (i.e., eye tracking disabled). (Right) Autofocals are also preferred for convenience, although only slightly over their current correction. Again, the depth-tracked mode fares poorly. Significance is indicated at the *P = 0.05, **P = 0.01, and ***P = levels. Nitish Padmanaban et al.
