Source: [None] URL Source: http://www.sciencefocus.com/qa/can-you-really-go-blind-staring-sun Published: Aug 21, 2017 Author: Steven A Collins Post Date: 2017-08-21 10:54:04 by no gnu taxes Keywords: None Views: 7146 Comments: 21 It’s possible, but the hazard is often exaggerated. Even at midday, a normal eye will only let in enough light to heat the retina by about 4°C. You need at least 10°C to cause thermal damage. Looking at the Sun during an eclipse for more than a minute can cause damage, because your pupils are more dilated during this, but it doesn’t result in total blindness and isn’t usually permanent. If the Sun is within 10 minutes of setting below a sea-level horizon, the more dangerous short-wavelength light is absorbed by the atmosphere and it should be quite safe to look at the Sun.

To: Vicomte13 (#15) Yeah. The "happy ending" was the arrival of the Spanish! Jeez Louise! Not sure if you're being sarcastic, but I'm sure the Spanish arriving at the end was not intended to be a happy ending. As per the movie title, it was more a revelation that the warring factions, while fighting amongst themselves, were oblivious to a greater threat that made their differences insignificant. It was an illustration of foolishness, and a message perhaps intended for the contemporary world.
