Are
solar eclipses dangerous ?
Solar
eclipses are not in the least bit dangerous, if observed with proper
care. Normally, one cannot look directly at the sun because it is too
bright. But during an eclipse, just before and after totality, it is
possible to look at the sun without immediate discomfort - and this
is where the danger lies.
You can damage your eyes without knowing it.
It is essential to use a safe viewing filter
to obsereve the eclipse. A filter that drastically cuts down
the strength of the sun's intensity by a factor of 10,000 is recommended.
Ordinary dark goggles or sun glasses are not suited for viewing the
eclipse.
During
the brief period of complete totality, it is safe to view the eclipse
with naked eyes. In fact the beauty of totality is not only safe but
truly and overwhelmingly awe inspiring. But remember that before and
after totality it is necessary to protect your eyes with proper equipment
and techniques.
For extra safety, restrict viewing time to not more than
15-20 seconds continuously.
Another
safe way to view the eclipse is by projecting the image on a screen
or a wall.
