Is there anyway to return them to clear or should I be looking for new ones?

**simple homer** answered this a few months ago:

“Meguiars sells a plastic polish and cleaner that has worked really well for me in taking care of the problem you describe, makes the lens look like new again, you can buy it at auto parts places like Pep Boys and Auto Zone.  
I really suspect that bleach would do much more damage than good on plastic…”  
For the original thread, do a search under “bleaching plastic.”
