Experts remind: when observing the solar eclipse, we must use the correct method and pay attention to protecting our eyes from injury.
When observing the solar eclipse, professional eclipse glasses or welding goggles should be used for observation. According to Zhang Yifan, director of the Department of Ophthalmology of the First Hospital of Qinhuangdao City, when the solar eclipse occurs, the brightness will increase relatively. If you look directly with the naked eye, or through colored glass such as candle-blackened glass, your eyes will be damaged, which may lead to permanent blindness.
In addition, sunglasses and sunglasses are not specially designed for observing solar eclipses. Even if you wear them, watching the eclipse directly will burn your eyes. When watching the eclipse with a telescope or taking pictures with a camera, you must add a filter in front of the telescope and lens, otherwise it will not only lead to the scrapping of the camera, but also damage your eyes.
