Those of us who wear glasses know foggy glasses can be quite an inconvenience. Glasses become foggy when water vapor condenses and collects on the lenses. This happens because the water vapor does not have enough energy to keep itself in a gas state once it hits the cool surface of lenses. Different factors cause fogging lenses, such as humidity, temperature changes, body heat, and face coverings (Young, 2020). With the pandemic still looming over the world, it is still common to see people wearing face coverings while working and performing day-to-day activities. Those who wear glasses or safety glasses at work know all too well that foggy lenses can get in the way. Wearing masks and face coverings has led to a growing demand for anti-fog safety glasses and solutions.
Safety glasses are important PPE because they are the best defense against eye injuries. They can keep debris and foreign objects from getting into your eyes, shield your eyes from chemicals, and provide UV light protection if you are working long hours outside. Fogging lenses cause workers to remove or not wear safety glasses in their workplaces, especially if they are wearing face coverings to protect themselves from getting sick. One solution to this problem is to provide anti-fog safety glasses to employees. Anti-fog safety glasses have their lenses treated with anti-fog sprays, gels, wipes, or coatings during the manufacturing process. Anti-fog solutions help keep lenses clear of fog and allow workers to continue performing their work safely.
Workers in various industries may benefit from anti-fog technology. Healthcare, food service and processing plants, and construction are just a few industries with workers who can benefit from using anti-fog safety glasses. Healthcare workers wear full PPE to protect themselves while treating patients with COVID-19 and other diseases. Safety glasses can protect food service workers from having food particles go into their eyes. Construction workers who work long hours outdoors can have their eyes protected from UV rays and not fog up as the weather gets warmer.
If anti-fog solutions are not available, these are a few tips to mitigate fogging (Cleveland Clinic, 2020):
- Ensure the mask fits securely over your nose.
- Use your glasses to create a seal at the top of your mask to prevent warm air from escaping from the top of your mask.
- Tape down the mask on your nose and/or cheeks using sports or medical tape.
- Wash your lenses with soapy water and shake off the excess liquid. Allow the glasses to air dry or wipe them off using a cloth before wearing them again.
