Firstly, I would like to explain the theory of lunar eclipse and solar eclipse in a dimpliest way. Lunar eclipse, is when the globe move to the middle of the sun and the moon, the globe block the sunlight that beams to the moon; solar eclipse, is when the moon move to the middle of the sun and globe, it hides the sunlight that shine to the globe. So, they are totally different! The lunar eclipse, as the light is not too strong to damage your eyes, you could watch it without sunglasses; the solar eclipse, you must use something to hide your eyes from hurt. Because of the tiny rays of lunar eclipse, with the hide of sunglasses, some of the process you may not observe its detail, so the sunglasses are unnecessary!
