Yes, the glasses, but especially the treatments on their lenses are ultra sensitive to temperature changes.

Who has never experienced when opening the oven door or lifting the lid of a pot of boiling water, that fog on their glasses lenses?

The repetition of these thermal shocks permanently alters the anti-reflective treatments.

Tips:

• Avoid leaving your glasses in the glove compartment of your vehicle.
• Remove your glasses before opening the oven door.
• Wash your glasses in lukewarm water instead of hot water.
