How Do I Make My Glasses Less Foggy When I Cook

Q. What harm can a foggy glass do to me?

A foggy glass can put you in harm's way. All the people with glass on their eyes are well familiar with this situation every once in a while. It is like you are blind even with your "four eyes." Fogging of the eyeglasses can occur spontaneously during the winter season or when there is heavy rainfall. 

Fogging can happen even while doing simple tasks like having a cup of tea or coffee, wearing a mask, or cooking. And this is a very annoying situation for most of the sufferers. The matter is even more irritating as fogging occurs again after a few minutes of cleaning the glasses. 

Sometimes, even one's life can be in danger when fogging covers up the glass. These situations are faced mostly while driving, operating heavy machinery, or working near fire like cooking, who must absolutely maintain clear vision all the time. 

Q. Firstly, please tell me how fog occurs?

It is essential to know how and why the fogging occurs in the glass to know how this annoying condition can be addressed. To understand this, it is important to keep in mind that glass is a supercooled liquid. Steam or water vapor generated from any reasons like cooking, working in humid environmental conditions, or wearing a mask will somehow contact the glass. 

Steam/vapor, whenever it gets in contact with this supercooled liquid, steam/vapor will immediately condense and forms small spherical droplets, which we commonly call fog. This process is most rapid; thus, fog immediately becomes dense and blocks the vision.

The time to worry about the foggy class is now a talk of the past. Here, we discuss various ways to reduce a foggy glass while cooking or other activities.

Choose anti-fog for glass spray.

The advanced spray technology has made it possible to design an anti-fog for glasses to use over any glass to make it fog-free. It is basically an activator liquid/spray which is applied on either side of the glass. 

Q. How does the anti-fog for glass spray work?

The liquid in an anti-fog spray is hydrophilic, which means that it attracts moisture and forms a thin layer instead of the formation of small droplets. The thin layer formed along the glass's surface does not affect the vision, unlike the droplet. Droplets are formed when anti-fog spray is not used and can cause visual disturbances.

Q. I just heard about the anti-fog spray for glasses. Can you tell me more?

Anti-fog spray for glasses may be a new thing for most of us, but this material has been available in the market for a long time, and has helped people with this spray. Another interesting fact about this kind of spray is that it is a long-lasting anti-fog material. Because the liquid content of the spray always sticks on the glass. The spray's anti-fog property is also not affected by the temperature changes, and the benefit of using the spray is the same in summer as it is during the winter season.

Q. I heard that the spray uses a chemical that can damage the glass surface later on, is this true?

There are lots of products in the market that uses other harmful chemicals and call them anti-fog spray. But the spray made available by is a genuine product and does not harm the glass surface. The spray protects the outer glass surface by forming a tiny film on the glass's surface, which looks like an additional coating on the lens's surface.

Q. Are there other methods that can be used along with the anti-fog spray to reduce fogging?

- Selecting appropriate glass frames that allow air circulation between the face and the glass.

- Wearing a headband during exercise to limit the seat from getting near the glass.

Most people use these methods only to know later on that these are ineffective methods.

Q. Many people suggest that washing with soap and water or applying a thin layer of shaving foam can prevent fog formation too, is it true?

There is no scientific basis for the application of soap or shaving foam to reduce the fog. Scientific and valid reasons back up the anti-fog spray made available by You can try both of these methods and find out the difference yourself. 

Q. I do not wear glasses. Is it still a useful product for me?
