Did you see the post on [creating camera lenses with SLA?](https://formlabs.com/blog/creating-camera-lenses-with-stereolithography/)

For the resin dipping in that post, the lenses were left on support bracing so that they wouldn’t need to be handled themselves.

As far as curing goes, a UV box is going to be much quicker than sunlight. Both light and heat initiate the curing process which is why we developed [Form Cure](https://formlabs.com/tools/wash-cure/). On a budget, [a small cure box can be rigged](http://forum.formlabs.com/t/recommended-uv-chamber-for-post-curing/3547) which should still prove much quicker than leaving parts out in the sun.
