Do I Need a Face Shield if I Already Wear Glasses?

As more individuals transition back to their daily routines, concerns about airborne particles and viruses persist. This article explores the role of face shields and glasses in protecting one's eyes during the ongoing pandemic. Let's delve into whether wearing glasses is enough or if additional protective measures like face shields are necessary.

Understanding the Protection Provided by Glasses

Many people, like myself, opt for a combination of cotton masks with a MERV 13 filter and flannel backing, complemented by large frame aviator glasses for eye protection. Aviator glasses are particularly effective because they cover a broad area, protecting the eyes from potential splashes and particles. However, while glasses play a significant role, they might not provide comprehensive eye coverage.

The Role of Face Shields in Eye Protection

While glasses offer a certain level of protection, they primarily cover a small part of the eyes. In contrast, face shields offer much broader coverage, protecting not just the eyes but also the face. They are especially crucial for situations where there is a higher risk of exposure to airborne pathogens.

Comprehensive Protection Against Various Factors

The applicability of face shields and glasses varies depending on the specific scenario. Here’s a breakdown of their usefulness:

COVID Prevention: Both glasses and face shields are essential. Glasses cover the eyes, but you still need a mask to protect the nose and mouth. A face shield offers coverage for both the eyes and the mask area, creating an extra barrier. Preventing Facial Contact with Contaminants: Glasses are effective for preventing contaminants from landing on your face, but not all glasses provide the same level of protection. Some prescription glasses might not offer the same coverage as aviator-style glasses. Preventing Eye Contamination: The effectiveness of glasses in protecting your eyes depends on the type of glasses you wear and the specific threat. For instance, normal prescription glasses may not be as effective as aviator glasses in dealing with debris and pathogens. Preventing Contaminants from Leaving the Face: Glasses only cover the eyes and do not address the issue of facial droplets that might come in contact with other surfaces or individuals.

When Face Shields and Chemical Goggles Are Essential

In high-risk scenarios, such as those encountered in hospitals or other medical settings, the use of N95 masks, face shields, and full protective PPE (Personal Protective Equipment) is paramount. Glasses alone are insufficient for preventing the spread of viruses and potentially harmful particles.

Preparing for a Worsening Situation

As the situation evolves, it's wise to have additional layers of protection. Having a couple of face shields and chemical goggles in your toolkit can be beneficial. Even if the pandemic situation stabilizes, it's a good idea to be prepared for potential future outbreaks or high-risk scenarios.

Conclusion

While wearing glasses can offer some level of eye protection, it is important to recognize their limitations and consider adding a face shield to your safety arsenal. Whether you are out in public or in a work environment, ensuring comprehensive eye and facial protection is crucial in safeguarding yourself and others.
