No problem with the lens unless you took a very long exposure and buckled the
iris which is hardly likely with a something as bright as the sun.   Your
eyes are a differrent matter though  -  i've no idea of the filter factor
required but astronomers regard the sun as magnitude 27 in brightness so
its pretty bright.  Whenever doing this kind of photography you'll have to
brackte shots anyway.   Why not try this technique for size - use a
telescope to project the image of the sun onto a white board and photograph
that instead.  You'd find it very easy to measure the light coming back at you,
and wouldn't risk your sight either.
