How to enjoy the solar eclipse safely
Most people underestimate how much light a pair of sunglasses blocks out. A typical dark pair removes around 80% to 90% of the visible light reaching the eye.
The article advises readers on how to safely observe a solar eclipse. Sunglasses, even those designed for sun protection, block too little light and can still cause eye injury. To view the eclipse safely, one must use ISO 12312-2 certified solar filters, which are much darker and specifically designed for this purpose. These filters reduce visible, ultraviolet, and infrared radiation to safe levels.
Sellers must be reputable and products thoroughly tested to ensure authenticity. Damaged or scratched glasses should not be used. Children require supervision. Ordinary objects like colander or a simple piece of card can project a safe image of the eclipse; however, direct viewing is not recommended. The British Isles will not witness another total solar eclipse for over a decade, making it a unique and valuable sight to witness without jeopardizing one's vision.
