You can be frustrated when you encounter glasses that always fog up while working or swimming. Fortunately, there are a few quick and simple ways to get rid of any condensation or fog on your glasses. In swimming goggles, you can use spit as a quick solution, or buy an anti-fog spray to completely solve the problem. If you have diving equipment, try burning the film to prevent the goggles from fogging. For other types of protective eyewear, try choosing glasses with anti-fog designs with good air circulation.
Step
Method 1 of 2: Using Homemade Solutions to Prevent Foggy Glasses
Step 1. Slow down condensation (change of water vapor or gas to liquid) by splashing cold water on your face
Minimizing the temperature difference between the face and the outside of the glasses will reduce condensation on the lenses of the glasses. Cool your face by splashing cold water 4-5 times right before you put on your glasses.
While it can solve the problem of moisture quickly, this method is not a good long-term solution. Try buying another pair of glasses if the problem persists
Step 2. Rub the inside of the glasses with a small amount of spit for an inexpensive solution
Dab a small amount of spit on each lens just before you put on your glasses. Spread the spit with your finger around the lens to form a thin film that will reduce the formation of condensation.
While this method of preventing dew doesn't last long, it's the most effective free method. Use this method if you need to prevent condensation from forming on the glasses quickly
Step 3. Use baby shampoo or other liquid soap to stop the condensation
Apply liquid soap to your fingers and rub it over the lenses of your work or swimming goggles. Dip the glasses in clean, chlorine-free water and wash them thoroughly with soap and water. A small amount of soap stuck to the inside of the glasses will stop the formation of fog on the plastic.
- Be sure to wash off any soap left on the glasses before you put them on to prevent soap from getting into your eyes. It's a good idea to use baby shampoo or something similar, as it won't sting your eyes too much.
- In addition to soap, you can also use shaving cream that is applied thinly to the lens. Again, always wash off the cream thoroughly to prevent the minty gel from getting into your eyes when you swim.
Step 4. Rub potato wedges on the lens to ward off water
Slice one potato until the flesh is visible. Rub the flesh of the potato on the lens of the glasses to form a thin protective layer that can prevent water and moisture from sticking to the lenses. Wash the lens using clean water to remove any visible residue.
While it can be used on plastic lenses, this method is usually most effective when applied to glass lenses
Step 5. Clean the glasses with toothpaste and a toothbrush
Apply a small amount of toothpaste to the inside of the lens. Use a clean, moistened toothbrush to spread the toothpaste, then gently rub the paste into the inside of the lens. Rinse the glasses with clean, non-chlorinated water to remove any remaining toothpaste.
Mild abrasion caused by brushes and toothpaste can remove the protective film of the lens, and clean it thoroughly. A thin layer of toothpaste left behind will prevent condensation from forming on the lenses of the glasses
Method 2 of 2: Using Commercial Products to Prevent Foggy Glasses
Step 1. Purchase an anti-fog spray or dew-dew cleaning sheet as a long-term solution
If you're reluctant to apply spit or soap to the inside of the lens, or don't think this method will last long, try buying an antifog product at a sports or swimwear store. Be sure to follow the included instructions for use. Below are some of the products you can try, and how to use them.
- Spray a small amount of anti-fog product on the inside of the goggles. Rub the lens with a clean cloth before you rinse it thoroughly. This is to remove any remaining spray and leave a thin layer of product on the inside of the eyeglass lens.
- Take a sheet of anti-fog product from the package and use it to wipe the lenses of your glasses.
Step 2. Wear protective goggles further away from your face to minimize condensation
The main cause of condensation on a mask or protective eyewear is moisture from the breath, or from the face turning hot and trapped inside the goggles. Look for glasses that are well ventilated, at a distance from your face to reduce heat and moisture that can build up on the lenses of your glasses.
Step 3. Choose anti-fog swimming goggles as an easy solution
Some swimming and diving goggles have been coated with a fog-blocking material. Visit a swimming or sports supply store for goggles that say "anti-fogging" or something similar to reduce condensation.
Step 4. Burn the protective film on the inside of the goggles
Diving masks are generally given a thin protective layer on the inside of the lens, which is easy to form mist or dew. Position the match about 5 cm from the lens, then move the flame, and aim it over the entire surface of the glass. Allow the glasses to cool on their own before you rinse them.
- Make sure you don't burn or melt the silicone, rubber, or plastic insulation sticking to the edges of the glasses, as this can make the glasses impermeable.
- If you're not sure you can do it yourself, take your goggles to a diving equipment store and ask if they can burn off the protective film on the lenses.
Tips
- Try not to touch the inside of the glasses with your fingers which can cause large smudges to appear due to the transfer of dirt and oil to the lenses.
- When swimming in a chlorinated pool, wash your goggles with clean water after you are done swimming. Chlorine can peel off the thin film on the lenses quickly, requiring you to apply more soap or anti-fog spray.
- Always keep the glasses dry when not in use. The moisture trapped inside the lens will turn into condensation when you swim later.
- Don't put goggles on your forehead when you swim. This can increase the humidity inside the lens.
