The safest way to view a solar eclipse is with special eclipse glasses or an eclipse projector. Sunglasses, even multiple pairs, do not protect your eyes. You can view the eclipse directly during totality, when the moon completely obscures the sun, without proper eye protection. You'll know it's safe when you can no longer see any part of the sun through eclipse glasses or a solar viewer. As soon as you see even a little bit of the sun reappear after totality, immediately put your eclipse glasses back on or use a handheld solar viewer to look at the sun.
