Believe it or not, a light spritz of Lemon Pledge is about the best solvent for cleaning eyeglasse lenses! I picked up a new pair of glasses years ago from an optical store, and was amazed to see the person I bought them from cleaning them just before she handed them to me. You would think the silicone would make a film on the lens, but it leaves them crystal clear. That tells me there is probably not enough silicone to cause any difficulty in automotive detailing.
