When you're ready to submit your revision, log on to https://www.editorialmanager.com/pone/ and select the 'Submissions Needing Revision' folder to locate your manuscript file.

Please include the following items when submitting your revised manuscript:

  • A rebuttal letter that responds to each point raised by the academic editor and reviewer(s). You should upload this letter as a separate file labeled 'Response to Reviewers'.
  • A marked-up copy of your manuscript that highlights changes made to the original version. You should upload this as a separate file labeled 'Revised Manuscript with Track Changes'.
  • An unmarked version of your revised paper without tracked changes. You should upload this as a separate file labeled 'Manuscript'.

If you would like to make changes to your financial disclosure, please include your updated statement in your cover letter. Guidelines for resubmitting your figure files are available below the reviewer comments at the end of this letter.

If applicable, we recommend that you deposit your laboratory protocols in protocols.io to enhance the reproducibility of your results.

Reviewer's Responses to Questions

Comments to the Author

1. Is the manuscript technically sound, and do the data support the conclusions?

The manuscript must describe a technically sound piece of scientific research with data that supports the conclusions. Experiments must have been conducted rigorously, with appropriate controls, replication, and sample sizes. The conclusions must be drawn appropriately based on the data presented.

Reviewer #1: Partly

Reviewer #2: Yes

The data should be provided as part of the manuscript or its supporting information, or deposited to a public repository. For example, in addition to summary statistics, the data points behind means, medians and variance measures should be available. If there are restrictions on publicly sharing data—e.g. participant privacy or use of data from a third party—those must be specified.

Reviewer #1: Yes

5. Review Comments to the Author

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: Generally, the manuscript is well written. However, revisions are required before acceptance.

1. In the experiment, participants were asked to wear contact lenses with varying degrees of defocusing to achieve visual degradation. The manuscript did not specify the extent to which they affected the increase in drivers' visual demands. No significant difference between the low-degradation and high-degradation groups was observed in the study, assuming that the participants could compensate to some extent. This is not rigorous; is there more detail.

2. 21 participants were selected for the experiment. The degree of astigmatism and other factors also have an impact on the experimental results, such as affecting the anchoring of eye tracker, which was not considered in the experiment.

3. The minimum gaze duration of the eye is 120 ms, therefore, eye and gaze data were divided into time bins of 120 ms. However, whether it is reasonable to divide the head movement data into a time bins of 800 ms? There's no basis here. And the coupling between data is questionable. In the discussion section of experimental results, it is found that drivers focus on the road ahead, assuming that they complete the auxiliary tasks faster than expected, which is lack of experimental verification. Therefore, there should be rigorous consideration in this aspect, which is also helpful for analysis.

4. According to the density distribution of the yaw/pitch Angle data of the driver's head, eyes and gaze, it is not precise enough to infer the location of the driver's gaze, which is two-dimensional. Different drivers test at different locations of the equipment, that is, there is a big difference in the original position in the spatial coordinate system, there is an individual difference in the projected position in front of them.

Reviewer #2: The topic is worthy of investigating and the conclusion is useful. The paper is overall well written and structured. There is one minor requested revision to the current paper, there literature review should be exhaustive and include the following driving simulator related studies:

[1] Examining the safety of trucks under crosswind at bridge-tunnel section: A driving simulator study, Tunnelling and Underground Space Technology, 2019, 92, 103034. https://doi.org/10.1016/j.tust.2019.103034
