Concerns are being raised around people buying 'knock-off' safety glasses to watch this week's solar eclipse. Safety officials remind observers to use ISO 12312-2 certified eclipse glasses during all partial phases of the eclipse. Use eclipse glasses, solar filters or make a pinhole projector using a cardboard box, tin foil and white paper.” The eclipse will be especially significant for Spain: the last total solar eclipse visible from the Iberian Peninsula occurred in 1912. The US and Canada will not experience totality from this eclipse and will see only a partial solar eclipse in limited areas.
