There are UV rays still glaring down from the visibible prominences of the sun which can cause serious damage to the human eye. one of the ways to view this amazing cosmic event is get a certain camer filter with a certain filter. look it up on Bing.
The other reason being, when there is eclipse, there is darkness and hence the pupil in our eye expand to absorb more light in order to see better. But when the moon moves further there is a sudden burst of light coming in and our pupils are still expanded(it takes more time for it to settle down) by then the burst of light directly falling on the eyes would have caused a lot of harm.
Added to this, during eclipse, the curiosity makes us stare at the sun for longer then the usual glance that we do of a fraction of second. This adds to the side-effects caused to the eyes during a solar eclipse.c
Because your mother hates you.
Or maybe its because your iris is degraded by a single focal point of light and light becomes more intensified if it wraps itself around the surface of the moon and the edges of where the light peaks over have less to move along, since there isn't an atmosphere to degrade the potency and if that were to make it to your eyes, it would burn a hole inside your retinas?
Or maybe the govt just doesn't want to grow a personal attachment to something that lasts for only 5 minutes and happens only once a year or 2.
Because even a sliver of the sun is intense enough to burn your retina. The full sun is so intense that you can't bear to look directly at it, so it's not much of a danger. But the partially eclipsed sun is much dimmer overall, and interesting, too. But the remaining sliver of sun can still burn your retina, it will just make a smaller burn than if you looked at the full sun.
