There is a wide variety of face masks available on the market, each differing in color, from white and black to pink. However, the standard medical mask is typically light blue. Why is there such a discrepancy in colors?

Firstly, it is common for doctors and nurses to don white lab coats during their shifts. Initially, they paired these coats with white masks, but it was later noticed that the combination of white coats and masks caused glare and eye strain for both patients and colleagues. Thus, they switched to light blue masks, which reduce glare from overhead lights and are easier on the eyes.

Additionally, medical professionals may encounter blood or other bodily fluids during patient treatment, especially during surgeries. The light blue color of the masks helps to disguise these fluids, reducing the visual impact and potential discomfort for patients and staff.

Lastly, the unique design of medical masks serves a practical purpose. The pleated, layered structure enhances water resistance, providing three layers of protection for the wearer. Furthermore, the outer layer is treated with a water-repellent coating, while the middle layer effectively filters airborne bacteria, and the inner layer provides direct protection near the mouth and nose.

Another clever design feature is the color differentiation between the outer and inner layers, with the outside being light blue and the inside white, ensuring the mask is worn correctly.

Now you know why standard medical masks are light blue. This information will hopefully enhance your understanding of the functionality and importance of wearing these masks, especially during these challenging times. Stay safe and protected!
