No, it is not safe to watch the eclipse using regular sunglasses. Only specialised eclipse glasses are safe to use. According to the National Aeronautics and Space Administration (Nasa), eclipse glasses are several thousand times darker than sunglasses, meaning they are safe for viewing the Sun. If you have a pair of eclipse glasses, Nasa recommends inspecting them for damage before using and discarding the goggles if torn or scratched.
