9 Tips for Preventing Fog On Your Eyeglasses

Foggy eyeglasses are a part of life for many people. Sports sunglasses and snowboard goggles often fill with condensation in response to frigid air, and even regular prescription lenses can fog up just because you’re sipping a hot drink in the cold outdoors. Why does this happen? Our opticians in Overland and St. Charles, Missouri, explain what’s going on – and provide helpful tips and tricks on how to prevent humidity white out in optics or laymen's terms: keep  your eyeglasses from fogging up.

Condensation is the cause

When moist heat, such as your breath or humidity in the atmosphere lands on a cold surface, such as your chilled eyeglasses lenses, it cools and transforms into tiny drops of liquid. These droplets, called condensation, create the film that you see as fog.

9 tips for stopping your eyeglasses from fogging up

  1. Anti-fog wipes: this is the easiest fix. The disadvantage of this simple hack is that you have to bring your wipes with you everywhere you go. Stock up on anti-fog wipes at our optical stores in Overland and St. Charles, Missouri.
  2. Anti-fog spray or cream: just like the wipes, anti-fog spray or cream also works well; it’s just a bit less convenient than the wipes.
  3. Clean eyeglasses with shaving cream: apply a small amount of shaving cream on both sides of your lenses, and wipe it off gently with a soft cloth and cold water.
  4. Spread white soap on your lenses: if you don’t have a can of shaving cream handy, white bar soap works as a good alternative. But don’t rinse the soap off with water. Instead, brush it off gently with a dry cloth until your lenses sparkle.
  5. Wipe lenses with saliva: this may be the fastest, cheapest way to prevent fog on your lenses. However, it can also lead to visual distortions, so don’t apply this fix right during sports.
  6. Eyeglasses that fit further from your face: some designs of frames sit further away from your face, providing better ventilation that can prevent condensation because the airborne water evaporates more quickly.
  7. Water-repellent lens coating: purchase eyeglasses with lenses coated with a water-repellent lens coating. The drawback of this solution is that it may prevent you from adding other types of lens coatings.
  8. Anti-fog sports eyeglasses: if you’re an avid outdoors person in the winter, you’ll benefit from buying a specialized pair of sports eyewear; check out our optical collection in Overland and St. Charles, Missouri.
  9. Take off your scarf: depending on the material of your winter scarf, it may be deflecting your breath upwards, where the warm air gets trapped behind your eyeglasses and leads to fog.

Note: these tips are for eyeglasses only; never use wipes, saliva, shaving cream or anything other than contact solution on contact lenses.
