1. General introduction:

In addition to N95 medical masks, medical protective clothing, antibacterial hand sanitizers, and nutritional supplements, which are all boosting resistance, recently, many people have heard about a COVID-19 face shield. With the desire to provide maximum protection for the health of themselves and their families, face shields have already attracted a great interest and been chosen by many consumers.

The face shield - The best choice for protecting.

According to Ph.D. Nguyen Hoang Yen - Director of the Children & Maternity center, the face shields are transparent pieces of mica cut to shape or affixed to cloth caps. Then, using a piece of foam and foam padding, create a bracelet on the head to keep the glasses from being too near to the face and support the nose, to keep moisture from breathing out, and to keep the glasses from fogging.

2. Uses:

The face shield is mainly used to protect the wearer's eyes. In the medical field, doctors also use products with plastic diaphragms in front to prevent secretions from patients splashing up during the surgery or endotracheal intubation… More people are now using the face shield to avoid droplets created by the COVID-19 pandemic, particularly in the difficult conditions caused by the Delta variety.

As we all know, the new Delta version spreads in both air and droplets, so in addition to the N95 medical mask, the face shield will give more safety to protect your eye area in the COVID-19 infection today.
