Because in a full eclipse the moon is close enough to the earth to block all the sun's disk and the light of this disk does not visually hide the corona. In an annular eclipse the moon is farther from the earth and not all of the sun's disk is blocked so there is enough light escaping around the block to hide the corona. .

When a solar eclipse happens the moon is in front of the sun. So you see the shadow of the moon you do not see the reflection of the sunlight though. The only thing you see is the shadow of the moon and the sun's corona.
corona* apex! You can see the corona better, but it is also visible with the naked eye but ONLY WITH APPROPRIATE PROTECTION!
The corona always emits light, but normally it is hidden by the light of the much brighter photosphere. During a total solar eclipse the moon completely blocks the photosphere, allowing us to see the surrounding corona.

You can see the corona during a total solar eclipse
Not with the naked eye, although we have special instruments - the coronagraph - that allow us to see the solar corona at any time. You can only see the solar corona with the naked eye during a total solar eclipse, and the Moon is already too far away to do that at apogee. If the Moon were further away than it is now, you would NEVER see a total solar eclipse.
Usually, we cannot see the corona because of the brightness of the photosphere. However, during a total solar eclipse, the corona shines beautifully against the dark sky. During a partial or an annular eclipse, a ring of the photosphere is visible around the Moon and the corona is not visible.
During a TOTAL solar eclipse, one can see the corona, the part that extends millions of miles out into space.
The Sun's corona.
The corona of the Sun can only be seen with the naked eye during a total solar eclipse. However, with a special telescope called a coronagraph, you can view the solar corona at any time.During a solar eclipse, you can see the corona as a bright ring. But compared to the brilliance of the Sun itself, the corona is invisibly dim. That's why you can only see it when the Sun itself is hidden behind the Moon.
You can see the corona and chromosphere.
The glare of the sun's photosphere. To see the corona with your eyes, wait for a total solar eclipse, or use a specialise telescope.
The light seen around the sun during a total solar eclipse is the sun's outer atmosphere, known as the corona. The corona appears as a shimmering ring of light due to the sun's intense heat and magnetic fields. This phenomenon is only visible during a total solar eclipse when the moon completely covers the sun, revealing the sun's outer atmosphere.
An even fainter layer of the sun becomes visible.
