4: Staring at an eclipse can blind you.
____ True ____ False ____ Only if you're not wearing specially made sunglasses
ANSWER: True. Never view the sun directly with the naked eye or with any unfiltered optical device, such as binoculars or a telescope!.
As sunlight enters the eye, it can damage the light-sensitive nerve endings in the back of the eye -- known as the retina -- causing vision loss.
Total and partial eclipses can lead to serious damage if precautions are not taken to prevent blindness. This is why there are only a few safe ways to view an eclipse, such as with a referred image. Regular sunglasses, exposed film, and even a welder's helmet are not safe.
