During solar eclipse why it is so harmful to see the sun directly inspite all other days?

Answer 1

The media tend to overblow this one. Here's the actual explanation:

1. When the sun is shining normally, you can't look at it for more than a fraction of a second or so because it's too bright. That's a good thing, because looking at it for an extended period would damage your eyes.

2. During an eclipse, you could conceivably look at it for much longer because most of the light is blocked. However, prolonged exposure will still damage your eyes. There aren't any "special rays" that only appear during eclipses; it's the normal radiation that you're exposing yourself to that causes the damage.

Bottom line: you CAN look at a solar eclipse for a second or two without any damage to your eyes.

Answer 2

Staring at the sun on any day is harmful.People seldom see into the sun directlyon normal days especially in view of its brilliance. Further with the brilliance of the sun cut off and with curiosity running high it is more likely for people to stare at the sun on an eclipse day .The heat and brilliant light can burn the macula causing blindness of varying degree. The UV light can hasten formation of cataract.

Answer 3

it rather is risk-free to observe the great part of a image voltaic eclipse rapidly with the unaided eye, binoculars or a telescope, in basic terms whilst the solar's photosphere is thoroughly lined by the Moon. in this era the solar is in basic terms too dim to be considered by filters. The solar's faint corona would be seen, and the chromosphere, image voltaic prominences, and probable even a image voltaic flare could be considered. besides the undeniable fact that, viewing the solar after totality would be risky.

Answer 4

definitely a good question. i have also heard people say that the sun shines brighter and more intensely during a solar eclipse, which is a total crock. obviously, the sun doesn't change its intensity in such a way, nor does it know there is an eclipse...

Answer 5

Mr Steve has given a good reply.Looking at the sun any longer than a few seconds will do harm irrespective of its position.Avoid also during sunrise,sunset or when partly hidden behind clouds when you may be tempted to look.
