Glasses that fog up due to changes in temperature are very frustrating because you suddenly can't see. Foggy glasses are more than just a nuisance, they can also be a safety threat if they occur while driving or operating machinery. Fortunately, by using special products, materials you have at home, or with simple adjustments, your glasses can be dew-free and you can see clearly.
Step
Method 1 of 3: Protecting the Lens
Step 1. Purchase an anti-fog product to protect the glasses
Many companies make products specifically designed to prevent fogging of glasses. It can be in the form of a spray or a gel and will reduce condensation when applied directly to the lens by forming a barrier that protects it from moisture condensation.
Most product should be sprayed onto both sides of the lens, allowed to dry, then wiped clean with a soft, dry cloth. Some products require a longer drying time, while others require that the spray or gel be rinsed off before wiping off. Check the product packaging for specific instructions
Step 2. Purchase anti-fog wet wipes to protect your glasses on the go
This is a rag that has been given a liquid so that it is easy and comfortable to use. Just wipe both sides of the lens using the tissue. These wipes are made for single use only. So throw it away when you're done using it.
Step 3. Purchase a professional anti-foam treatment for a longer lasting solution
Check with your ophthalmologist for availability and the cost of applying a one-time coating to your lenses to permanently prevent moisture. This option will be especially useful when there are drastic and/or frequent changes in temperature, or when moisture will pose a safety hazard.
Be prepared to leave your glasses on for a few days and spend around IDR 700,000-1,500,000
Method 2 of 3: Using Materials at Home to Prevent Dew
Step 1. Apply shaving cream to the lens to create a protective film
Before going out in the cold, apply a small amount of shaving cream to both sides of the lens, then rub it in. Allow the shaving cream to dry before wiping off the residue with a soft, dry cloth.
Some people even say shaving cream lasts longer than store-bought dehydrating products
Step 2. Rub a bar of soap onto the lens to create a clear protective film
Apply a small amount of soap, let it dry, and gently wipe off the residue with a soft, dry cloth. The soap will work like shaving cream and make the lenses clear and dew-free.
Step 3. Spit on the lens if you have no other choice
You can apply a small amount of saliva on both sides of the lens, then wipe it with a soft, dry cloth. Only do this if no other ingredients are available, as saliva can contain oils or substances that could potentially damage the lens.
Method 3 of 3: Making Simple Adjustments
Step 1. Keep the glasses away from the face
Glasses will trap heat and moisture when they are too close to your face or eyes, and this will increase the chance of condensation forming. Slide the glasses down the nose to allow more room for air circulation and less condensation.
Step 2. Check to make sure your clothes are not blocking the airflow
Items such as scarves and high-collared coats can hold moisture in and push it up, which can cause glasses to fog up.
- If you can't avoid wearing this type of clothing, unzip the coat or leave the scarf hanging open to allow air to circulate better. Alternatively, tuck the garment under your chin so that your breath can flow outwards instead of upwards.
- During exercise, use a sweatband to absorb sweat and reduce perspiration.
Step 3. Do not store glasses in cold weather
Wearing cold glasses on a warm body will create a more intense dew effect due to changes in temperature. Instead, keep your glasses indoors (instead of in your car) to help reduce condensation as you move from warm to cold places.
