Keep lenses clean to reduce fogging

Clean your lenses regularly with a proper lens cleaner and microfiber cloth, ensuring they are completely dry and streak-free. Clean lenses fog less because dirt, oils, and smudges create microscopic rough spots where moisture condenses more readily.

Why It Works

Smudges and skin oils on a lens surface act as nucleation sites -- tiny irregularities where water vapor can condense into droplets more easily. A clean, smooth surface gives moisture fewer places to cling, so fog forms more slowly and dissipates faster.

Tips

• Clean lenses at least once a day, especially before situations where fogging is likely (cooking, cold weather, wearing a mask)
• Avoid wiping with paper towels or clothing, which can leave lint and micro-scratches that worsen fogging over time
• Pair this with an anti-fog treatment for the best results
