This talks about IOP changes on using smart phones. And it increases more when done in low light. I saw a lot of links for myopia in children and links to light exposure

These articles are talking about overall exposure - spending time outdoors and find it to be of statistical importance. https://webvision.med.utah.edu/book/part-viii-psychophysics-...
See the section on illumination "For recognition tasks, visual acuity is greatly affected by the level of background luminance. (Graph) One theory put forward by Hecht is that within the rod population and within the cone population, there are differing sensitivities which are distributed randomly. Therefore, at high luminance, all cells are active for a high level of visual acuity. At low luminances, only cells sensitive to that level of luminances are active and because they are distributed randomly, the retinal mosaic is coarser thus a lower level of visual acuity is achieved (Graham, 1965). Another possible explanation is that under limited quantal availability, quantal capture is more probable in the para-central and peripheral retinal due to greater spatial summation. Since photoreceptors density in this area is low, resolution is poorer. As light levels increase, quantal capture occurs more successfully at the central retinal (macula and fovea). A higher level of visual acuity is achieved due to the high photoreceptor density.
" I am not sure what all of these terms mean but I guess some good sources for you to check out. Do share if you find something interesting. |
