Book 31, Question 129
What could happen if you aimed binoculars at the Sun?
Binoculars gather light and focus it into your eye.
Sunlight is so bright that this can burn the tissue at the back of your eye and damage your vision, sometimes for good. It can happen in a second, and it doesn’t hurt right away. The same goes for telescopes and cameras. Always aim binoculars away from the Sun, even when looking at the sky.
