How to safely observe a solar eclipse

The safest way to watch an eclipse is by projection old technique. Take a piece of cardboard and make a small hole in the center. Pointing at the Sun cardboard that light passes through the small hole and has to project on a flat white surface.

Be especially careful with the glasses for solar observations that are sold in stores, because not all are certified to ensure that they are treated with appropriate filters to prevent eye damage.

To avoid the risk of irreversible damage to the eye:
Do not look at the sun directly with the naked eye
Do not look at the sun with telescopes or other optical devices that do not have adequate filters
