Looking at the sun, even during the totality phases of a total
eclipse can _permanently_ damage your eyes.
Looking at the eclipse with the naked eye is damaging, but looking
at it with an optical device (such as binoculars or a telescope) is
even more dangerous, as the device is designed to focus incoming
light on your retina, destroying them faster.
There are safe ways of observing the eclipse:
1. Use #14 welders glass as a filter for either your eyes or any
optical instrument such as a camera, telescope or binoculars;
2. Use a pinhole to project the image onto a piece of cardboard or
paper and look at the projected image only.
3. Find a local amateur astronomer and really enjoy the view through
a telescope suitably protected with a solar filter.
