Looking directly at the sun, purchasing ‘NASA approved’ eclipse glasses, and driving are the three major things experts warn not to do during and ahead of Monday’s total solar eclipse.
Even brief exposure to the light of the sun can lead to permanent ocular damage because of the photosensitive cells that coat the inner wall of your eye, which are very sensitive to the intense light and heat generated by the sun.
Direct exposure can kill off these cells, which will not regrow naturally in the same way as other cells in the body.
But be careful which eclipse-safe eyewear you decide to trust. NASA does not approve any specific brand of solar viewer, so NASA branding is a surefire sign that your glasses are fakes.
Last month, the American Astronomical Society (AAS) warned that counterfeit solar eclipse glasses were flooding the American market.
Many sellers fraudulently use the branding of bodies like the AAS or NASA to appear legitimate.
However, they may not give you the right level of protection and could lead to severe eye damage if used.
And finally, get off the road. Even for the most vigilant drivers, the total disappearance of the sun is going to be a significant distraction.
As the moon’s shadow sweeps across the Earth, areas will suddenly plunge into darkness and shadows will become strangely distorted.
