Technological advances in optical performance, channel size and image enhancement now deliver the benefits of visual resolution and diagnostic performance comparable and often superior to c-OGD. To test whether the aforementioned effect can be explained by increased sensitivity to blue light above fixation, we designed a follow-up experiment that presented luminance-matched color stimuli (red, green, and blue) separated by either the horizontal or vertical meridian of the computer screen and paired with luminance-matched gray on the other side of the screen. We hypothesized that (i) blue would result in a larger constriction of pupil size due to a general bias or sensitivity to blue light, (ii) that blue light above would induce larger pupillary constrictions compared to blue light below, and (iii) that this effect would be specific for the blue channel and this orientation. These hypotheses are consistent with data presented in Experiment 1, and an ecological perspective that years of experience in the world with a blue sky (correlated with sun brightness) has adapted the system to anticipate or exaggerate the PLR specifically when blue is overhead. Participants The studies involving human participants were reviewed and approved by ARL Institutional Review Board. The patients/participants provided their written informed consent to participate in this study. Author Contributions The TV’s coverage of the DCI-P3 colour gamut is now 79%, which is better but still not great. However the biggest improvements are to be seen in peak brightness. With Custom mode selected and local dimming enabled we saw peak brightness reach 804cd/m2 with a 25% patch of white in the centre of the screen and a still respectable 704cd/m2 with the standard 10% patch displayed, up from 439cd/m2 at launch.

This result was highly consistent across subjects as observed in the individual correlation maps for the green and blue channels ( Figure 3, right). While location of fixation was not experimentally manipulated or controlled in this analysis, these results indicate that fixations toward the horizon may have comprised the majority of fixations. When this well-matched visual pattern of blue on top and terrain on bottom fell onto the retina, it induced robust pupillary responses that accounted for a large degree of variance in the pupil signal by comparison to other areas or features of the environment. One surprising aspect to this finding is that the blue sky itself had lower luminance intensity compared to the terrain below, which was composed of more red and green hues that tend to carry stronger luminance signals (See Supplementary File 1). So while the strength of the luminance signal tended to be stronger below fixation, it was the specific temporal pattern of blue luminance above fixation that correlated most with pupil size, indicating the strength of this contextual effect. Confirming the “Blue Sky Effect” There is a substantial need to improve GI endoscopy capacity in the UK, with units in the pre-COVID-19 era unable to meet their targets for urgent 2-week cancer wait (26.3%), routine 6-week DM01 (31.3%) and surveillance procedures (36.6%). 2 Further impacts caused by COVID-19 have exposed patients to diagnostic delay for upper GI cancer with an estimated 759 oesophageal and 320 gastric cancers missed during the COVID-19-impacted period in the UK, 3 and modelling studies estimating a 10% increase in oesophageal cancer deaths up to 1 year after the pandemic. 4

Foreshadowing our results from Experiment 1, the correlation maps surprisingly revealed that pixels closest to fixation actually varied the least with pupil size, contrary to our hypothesis of a foveal bias. The maps instead uncovered a distinct spatial pattern to indicate a significant contextual effect in which blue pixels, specifically located above the gaze position, had a disproportionate influence on pupil size. These results were interpreted to be related to a blue light from above or “blue sky effect,” reasoning that from an ecological perspective it would make sense for the brain to anticipate a brightness change whenever there is a visual pattern resembling a blue sky overhead due to its association with daytime and sunlight ( Laeng and Endestad, 2012; Naber and Nakayama, 2013; Castellotti et al., 2020). In Experiment 2, we performed a controlled laboratory experiment that paired a gray patch with luminance-matched red, green, and blue patches located either on the top, bottom, left, or right relative to the control (gray). Results of this follow-on study confirmed our hypothesis, demonstrating a significant and highly specific “blue sky effect” on the PLR. Participants Audio quality remains as good as ever, although that didn’t need improvement as badly as picture quality did. It isn’t as good, it must be said, as if you were to connect a decent dedicated soundbar, such as the Sonos Beam 2, but better than you’ll get with most TVs at around the price of Sky Glass.Indeed, Sky Glass plays host to a full 3.1.2 Dolby Atmos-compatible audio system. Four drivers are housed in the “soundbar” part of the TV – one centre speaker, one 120mm bass woofer and two stereo drivers – and there’s a pair of upward-firing Atmos speakers in the top corners of the TV set to deliver Atmos’ height effects. Colour performance while viewing standard dynamic range content (SDR) using Movie mode colour proved decent, with Sky Glass covering 95.1% of the Rec.709 colour gamut when measured using our colorimeter and the Calman colour calibration software.These factors, combined with its excellent safety profile and minimal cardiorespiratory effects, 10 offer flexibility for endoscopy to safely expand beyond the traditional boundaries of the endoscopy unit and into novel outpatient spaces.

The remaining authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. Publisher’s Note In this study, we examined correlations between pupil size and dynamic image statistics in the context of a free visual search and navigation task in a 3D virtual environment. We found that blue and green pixel intensities had a disproportionately large impact on pupil size in comparison with the red color channel. Furthermore, we found that visual scenes in which blue was predominantly overhead had the strongest influence on pupil size, which led us to hypothesize a “blue sky effect.” We conducted a follow-up controlled laboratory experiment and found evidence consistent with our hypothesis, showing a specific sensitivity of the PLR to blue light when it is located above fixation. From an ecological perspective, we speculate that the heightened sensitivity of the pupillary system to this visual pattern may be a useful adaptive response due to the persistent association between sunlight, large increases in brightness, and the blue sky in our daily lives. From a practical standpoint in terms of pupillometry research, the findings of this report suggest that equating luminance alone may be insufficient to account for luminance effects on pupil size if multi-colored stimuli and/or naturalistic images are used in psychological research. More research is necessary to fully understand how best to account for the influence of light on pupil size for studies or applications in complex visual environments outside the laboratory.
