@F1Yankee – I’ve not managed to find much specific information on eyes other than one solitary paper, and I’m not sure about the evidence behind the blink rate, but I’ll delve further.
@verstappen – That should be straightforward enough – I’ll give it a go.
@raymondu999 – I’m a doctor so have a pretty decent understanding of human physiology. Response to sport is exercise induced and isn’t too dissimilar to stress responses.
In any case, it’ll take me a while to write, reading up a lot of papers at the moment on the topic! Thanks for your feedback :)
