Looking straight at the sun, even when there isn't an eclipse, may do serious harm to your eyes. It is imperative that you use solar eclipse-specific eyewear during the eclipse. In August of last year, I ordered a pair of Eclipse Safe Solar Glasses from Amazon. When the moon completely blocks out the sun, you may take off your sunglasses. After around 10 minutes, the Sun will begin to peek out from behind the clouds again, at which point you'll need to put those special spectacles back on. It's crucial that you use eye protection.
