: How to observe an eclipse ?
To observe the solar eclipse with the naked eye, it is imperative to wear special glasses . Conventional sunglasses are not sufficient to protect the retina. During the eclipse, with the decrease in brightness, the pupils will tend to dilate. When the sun suddenly reappears, severe retinal damage may occur . These burns are not painful, so we must be particularly careful. Tips of the type watching the eclipse through a CD or through smoked glass are not effective.
To protect your eyes and enjoy the eclipse better, go to an astronomy club where you can observe the eclipse indirectly by projection. The simplest solution: make a small hole in a cardboard, direct it towards the sun and observe the projected eclipse.
