Wear Protective Goggles To Watch Solar Eclipse
Solar eclipse is a wondrous spectacle
Solar eclipse is a wondrous spectacle. It is so shocked and charming that everyone would like to appreciate it when it comes only once in a thousand years. However, you should know despite that it is wondrous; it hurts, because sunlight is rather strong. If staring with naked eyes for 30 seconds, you would probably lose 30% of your sense of sight. Therefore, you should learn correct ways to watch solar eclipse and share them with people you care about.
One of the best ways for you to keep eyes from getting burnt is to wear
protective goggles, which are thought to be able to reduce sunlight shining into eyes. Here below are some tips telling you how to use those protective goggles.
Firstly, check carefully whether the goggles are in good condition. If there is any damage, stop using immediately. Children should use goggles under the corrective guidance of their teachers or parents.
Secondly, put on the goggles 30 minutes in advance. Everyone should have such an experience that when entering a dim room from outside places, where sunlight is rather strong, one would find it hard to see objects clearly or even hardly to see them in the room. It would take about half an hour for the vision ability to get recovered. This phenomenon is called dark adaptation. Therefore, it is necessary for one to put on goggles in advance, so as to make the eyes get accustomed first.
Thirdly, take a rest for about 30 seconds every 3 minutes. Never watch the sun for too long time. Although to some extent protective goggles could soften the sunlight, watching the sun for too long time, eyes would be heavily pressed.
Fourthly, wear protective goggles during the partial eclipse period, and take off during the total eclipse. That is to say it is possible to watch total eclipse with naked eyes, however, 4 to 5 minutes later, put on eyewear again.
Tips above are fairly important, for if you neglect them, your eyes are probably to get burnt. Remember never watch the sun with naked eyes. What is more, for better protection, one is suggested to buy those goggles in former shops. They are thought to soften sunlight and filter the infrared and ultraviolet effectively. Those sold along the street are not well quality guaranteed.
