Looking directly at the sun, buying ‘NASA approved’ eclipse glasses and driving are the three most important things for experts https://www.dailymail.co.uk/sciencetech/article-13283801/Solar-Eclipse-3- things-NOT- do.htmlduring and before Monday’s total solar eclipse.
Even brief exposure to sunlight can cause permanent eye damage due to the photosensitive cells that line the inner wall of the eye, which are very sensitive to strong light and heat generated by the sun.
Direct exposure can kill these cells, which will not grow back naturally in the same way as other cells in the body.
But be careful which eclipse glasses you decide to rely on. NASA does not approve any specific brand of sun visor, so the NASA brand is a sure sign that your glasses are fake.
Last month, the American Astronomical Society (AAS) warned that counterfeit solar eclipse glasses were flooding the US market.
Many sellers fraudulently use the branding of organizations such as the AAS or NASA to appear legitimate.
However, they may not provide you with the proper level of protection and could cause serious eye damage if used.
And finally, get off the road. Even for the most attentive drivers, the complete disappearance of the sun will be a major distraction.
As the moon’s shadow sweeps across the Earth, some areas will suddenly be plunged into darkness and the shadows will become strangely distorted.
