Eliminating experiences on the frog (Hollwich) and on the duck (Benoit) showed that these stimuli \u2013 beside vision \u2013 use a separate way, the so-called \u2018energetic portion\u2019 of the visual pathway (Hollwich). In compared studies on blind and on temporarily blind patients involved by cataract in both eyes, we found significant low levels of ACTH and cortisol. The levels normalized after cataract extraction. \u2013 Furthermore, we studied the influence of strong artificial illumination (3,500 and 3,200 lx) on healthy persons with considerable and, on the other hand, with minimal difference of their spectral composition to daylight. We found stress-like levels of ACTH and cortisol in the first group. These findings explain the agitated mental and physical behavior of children staying the whole day in school under artificial illumination with strong spectral deviation from daylight. Therefore, to avoid mental and physical alterations, the spectrum of artificial illumination should be largely similar to that of natural light.<\/jats:p>","DOI":"10.1159\/000308973","type":"journal-article","created":{"date-parts":[[2010,3,31]],"date-time":"2010-03-31T05:08:54Z","timestamp":1270012134000},"page":"188-197","source":"Crossref","is-referenced-by-count":12,"title":["The Effect of Natural and Artificial Light via the Eye on the Hormonal and Metabolic Balance of Animal and Man"],"prefix":"10.1159","author":[{"given":"F.","family":"Hollwich","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"B.","family":"Dieckhues","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2010,3,30]]},"container-title":["Ophthalmologica"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000308973","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,2]],"date-time":"2026-05-02T06:58:42Z","timestamp":1777705122000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000308973"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010,3,30]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000308973","archive":["Portico"],"relation":{},"ISSN":["0030-3755","1423-0267"],"issn-type":[{"value":"0030-3755","type":"print"},{"value":"1423-0267","type":"electronic"}],"subject":[],"published":{"date-parts":[[2010,3,30]]}}}
