What will happen if look at(or in the direction of) a distant object through a convex lens?
Nothing disastrous will happen, so why not give it a try ?
However, do not -- repeat do not -- use the sun as your distant object !
In case you had expected some other kind of answer: what is it you want to know / are cusrious about ?
It depends very much upon where you hold the lens with respect to your eye and the object.
Look at this link, this link or this link to find the various cases of object and lens position. If you can follow the last (excellent video) link through to the end you will understand the whole thing, I think.
Something fishy with the second link:
This site has been blocked by the network administrator.
Block reason: Gateway GEO-IP Filter Alert
Strange. It works fine for me and it's a dot org site. The link is http://www.leydenscience.org/physics/electmag/raylens.html. Try it manually.
The company network system, where I work, also blocks it with the same warning
