Do Safety Glasses Normally Fog Up?

Safety glasses are a necessity in any dangerous workspace. They are anti-fogging, scratch-resistant, and smudge-proof. Also, they prevent you from putting yourself within the sight of serious harm. You should always wear safety glasses when doing any task that could cause damage to your eyes such as using power tools, welding equipment, or any other risky activity. On top of that, safety glasses can also protect your eyes from flying debris, dirt, and splattering liquids.

However, despite the usefulness of safety glasses, they do have some drawbacks. A common dilemma with safety glasses is the incessant way some of them fog up even when they seem like they shouldn’t. But should they even be fogging up in the first place? Let’s take a look.

What Are the Leading Cause of Foggy Glasses?

One of the most common factors that cause foggy safety glasses is humidity. When the temperature drops and humidity increases, moisture condenses on the lenses of your glasses. This may cause them to become cloudy or milky white.

Likewise, fogging in your glasses can be caused by the reflection of the sun off of your glasses. This can cause them to get too hot, and react to that heat by fogging up. Polarized glasses might be a great option for you in you typically work in a sunny environment.

Are Safety Glasses Supposed to Get Foggy?

Safety glasses are not supposed to get foggy at all! Many of them are covered in coatings to prevent moisture from remaining on the glasses, therefore preventing them from becoming unusable with fog. However, anti-fog coatings do not protect against windblown rain, which can still cause some fogging.

Why Are My Safety Glasses Fogging Up Then?

Unfortunately, the coating on safety glasses does not last forever and can be worn down by normal wear and tear. However, you can do your part to prevent the annoyance of foggy lenses by taking good care of your glasses. Luckily, most pairs come with user manuals that will give you instructions on how best to care for your glasses.

If you are convinced that they are fogging up for other reasons, here are some places to start.

Counterfeit Anti-fogging Layer

Fogging is a common complaint among individuals who purchase cheap glasses that are sold at department stores. In such pairs, the coat has been manufactured with a poor-quality anti-fog coating, and after several washes, the coating wears off and the visor becomes cloudy. The solution to this problem is simple—get your glasses from a reputable manufacturer and choose a pair with a good quality layer.

Extended Use

Fogging can also occur if the user wears glasses for long periods of time— especially if they are working outside. When working outside the lenses being to accumulate a thin layer of mineral deposits eachtime, which then eventually forms a crusty surface on top of the lens. This slowly destroys the anti-fog layer, which is another reason why your glasses may not be performing well.

Wrapping It Up!

Safety glasses are often overlooked, but they play a huge role in keeping your eyes healthy and protected throughout the day. If you notice that your glasses becoming cloudier than usual or that your vision starts to deteriorate, then you may want to consider buying a new pair (just steer clear of the fake ones).
