Pierre,
 
That was me. The repair tech Bernie O'Doherty gave me that tip, and it did have something to do with the sand that was used to make the glass. Apparently the "sun tan" would reduce or eliminate the yellow cast that the Lomo's can develop over time. Maybe keeping them in a case in a dark closet isn't the best for them!

We have a post early this year about lens Russian or Zeiss where the glass
shift color because of the sand they used to made the glass...
If i remember in the post the persons propose to expose the lens to the
natural light near a window for few days and put a aluminum paper on the
other side for reflexion.The glass then recover the transparency or is
original color....

We protect the lens and put them all the time in a dark area maybe if they
got some sun tan  for few hours this could dry them and avoid other problem
?

Any optical specialist on the list ?
