Make sure your eclipse glasses are safe
Before putting your eclipse glasses to use, however, you must always ensure that there are no pinprick holes in the lenses.
This is as true for eclipse glasses that have been stored away since the last solar eclipse, as it is for brand new ones: make no assumptions!
In the event that you do discover your eclipse glasses are damaged, do not attempt to fix them: get your hands on a brand new pair.
You also need to make sure you buy properly certified solar eclipse glasses from a reputable manufacturer: accept no substitutes, as buying homemade versions risks damaging your eyesight.
The International Organization for Standardization recommends only buying eclipse glasses that have the ISO 12312-2:2015 certificate, as these are certified as being safe for observing the Sun, including during a solar eclipse.
Myths abound regarding using smoked glass for observing solar eclipses, and we've even heard one erroneous claim that black bin liners can be used as a material for safe solar observing, but these methods are both ineffective and dangerous.
You should only use eclipse glasses or other certified solar observing equipment when observing an eclipse.
However, during a total solar eclipse, at the point of totality - when the Sun is completely covered by the silhouette of the Moon - many viewers take this opportunity to remove their eclipse glasses and enjoy the full spectacle.
If you do this, don't forget to put your glasses back on once the Moon's silhouette begins drifting away from the solar disc again.
