Fernando Fraccaro Thiene explains why should not look at a solar eclipse

The sun cannot be underestimated, Fernando Fraccaro Thiene assures. If you look at the sun for a long time, you can damage your retina and spend the rest of your life with a dark spot in front of your eyes or even go blind, warns Fernando Fraccaro Thiene. The same effect happens if you observe a solar eclipse without special protection. It only seems that during an eclipse, the sun does not shine as brightly as usual. In fact, at this time, infrared and ultraviolet waves – the same length and strength of impact as on a fine day, explains Fernando Fraccaro Thiene.
