Wearing glasses is already quite cumbersome, and if things couldn’t get any worse, your glasses may start to fog up and make seeing more challenging. Certain conditions are responsible for lenses to become foggy or steamy, and mostly, they have something to do with changes in the weather or the temperature of your surroundings.
Here’s a situation that can help explain the science behind fogging glasses: When you’re in a room that has a colder temperature than the outdoors, your glasses will naturally be colder too. But when you go outside, your glasses fog up because the steam or vapor in the warm air hits your cold glasses and turns into droplets of water. This fogging then continues until your glasses warm to the dew point.
Here’s another possible scenario: You’re wearing your glasses too close to your face such that when you breathe, the air has no way out. Thus, it reaches the lenses, giving your glasses a foggy coating. The same happens when the sweat from your skin evaporates, as the vapor cools and condenses or turns into moisture, hits your cold glasses, and fogs them up.
Luckily, clearing your glasses of that pesky foggy film is manageable. Read on to find out how you can keep your glasses fog-free.
1. Add anti-fog coating on your lenses.
The anti-fog coating works by blocking moisture that could stick to your lenses. You can specifically request your optical clinic, shop, or store to apply the coating (either a temporary or a permanent one) to your glasses.
If you decide to have an anti-fog coating on your lenses, you should refrain from touching or wiping the lenses that might cause the coating to peel off.
2. Use anti-fog wipes, sprays, or creams.
If your glasses don’t have any anti-fog coating yet, commercially made anti-fog solutions can be quite handy.
Anti-fog wipes are formulated with compounds that prevent water droplets from forming on the surface of your glasses. The spray or paste form can be applied directly to the lenses. You then wipe and buff it off in a small, circular motion using a clean fabric until you clear your glasses with the application.
3. Clean your glasses with a dab of shaving foam or cream.
This neat hack can be especially useful if you’re at home with no commercial anti-fog solution on hand. On your finger, place a tiny dab of your shaving foam and rub it on your lenses. Afterward, wipe your glasses clean with a soft fabric (cotton or microfiber cleaning cloth) that’s suitable for lenses and eyeglasses.
Alternatively, you can use tiny shavings from a bar of soap to clean your lenses in the same way that you would use shaving foam.
For best results: Let the shaving cream or foam dry when wiping off any excess amounts off your lenses. This trick should help create a clear layer on the surface of your glasses, serving as a buffer against changes of coldness or hotness.
This item also has cleaning properties that may be suitable for your foggy glasses:
• A solution made from three parts water and one part white vinegar – rub both sides of your glasses with the solution. No need to rinse or wipe away.
4. Choose your rainy season essentials and accessories.
Bundling yourself up in rainy season clothing should not cause air to be trapped around your spectacles. This might mean doing away with scarves or face masks, but if you can’t stand the weather without your scarf on, wear the type with weaves that are coarse enough to let the air pass through.
Contact lenses can also work great during the cold season, although you should be careful about having dry eye syndrome. Using eye drops can do the trick though.
5. Position your glasses further away from your face.
Earlier, we mentioned that water vapor from your breath changes into moisture, as it gets trapped onto the cold surface of your glasses. By wearing your glasses slightly further from your face, air can flow move quickly between your skin and lenses such that the amount of heat difference decreases. Some eyeglasses in the Philippines are fitted with an adjustable nose piece that can help solve this type of problem.
6. Take your glasses off.
This may be the most logical solution when your glasses start to fog. Apart from not giving the fog to chance to get worse, your glasses won’t be needing constant wiping which could leave marks or scratches on the lenses.
Another practical tip to help you achieve a fog-free look on your glasses is to avoid abrupt temperature changes. Wait sometime before going from cold to hot areas to help prevent fogging on your glasses. For example:
• Upon entering a building, stand by the doorway (where the air is warmer than outside but cooler than inside the main premises) for a minute or two.
• When you’re in the car, adjust the heat gradually especially when your hands are not free to simply remove your glasses and wipe off the fog.
Foggy glasses are both a bother and a hazard, which should not be taken lightly. Not only does it pay to know what’s causing the nuisance, but one should likewise understand and apply the precautionary measures to keep all the fog at bay and maintain good vision.
