captpackratI made a useful discovery today. Apparently the process that makes my Transitions lenses get darker is exothermic (and the lightening process is endothermic). The glasses get darker faster if the lenses are cold, while they stay dark for a long time after going indoors if they are still cold.
If I warm the lenses under hot water, they'll lighten much faster than if I left them alone.
