How To View The Total Eclipse Without Going Blind And Without Glasses
All we’ve heard is to not look at the eclipse without approved, safe eye wear, or you could severely damage your eyes. Well, now we see that while people may risk serious eye damage looking at partial phases without proper protection, there is a way you can actually view it without glasses.
After all we’ve been told about this, for over a year now, you may ask how you can get away with not wearing special glasses. This is not a trick question, as though the answer is, “You don’t need glasses viewing it on television,” though that is true. According to foxnews.com/science, it is safe to look directly at the event during totality, only when the sun is blocked in its entirety by the moon. Of course, that's a short two and a half minute window.
Dr. Ralph Chou, an eclipse watcher and professor emeritus at the School of Optometry & Vision Science at the University of Waterloo in Ontario, says, “Not everyone will be able to see the total solar eclipse, though many people may be able to see a partial eclipse.” Chou emphasized that if you’re in an area where only a partial eclipse can be viewed, there’s never a safe time to look straight at the sun. So that makes it very important to only take off the protection in the middle of totality – not until after it has been established at the beginning – and only until just before the end of it.
You can pull this off unscathed if in Casper, in totality, but if in Cheyenne, I wouldn't try it.
So, for the above question, “How to view the total eclipse without going blind and without glasses,” the answer is, “Make sure that’s only if you are in a totality path,” on the “Dark Side of the Moon.”
