It is very easy for manufacturers to overlook some vital features of the face shield due to their current demand, some of these features may look irrelevant but given the infection rate of the coronavirus every detail should be adhered to, therefore you need to be extra vigilant when buying these face shields especially when you are buying in bulk, you can imagine how many people you can expose to the deadly coronavirus if you purchased substandard face shields, this can make you be held responsible for the damages resulting from the virus. The difficulty in selecting the right face shields normally is a result of inadequate knowledge of features to look for in a reliable face shield to give you more insight we have gathered some information regarding aspects you need to look for to buy a safe and reliable face shield.
The very first thing you need to pay attention to is the user comfort, this is important because you will be wearing the face shield most of the time, therefore, consider things such as shape, size, and designs. You need to realize that some face shield will sacrifice a certain percentage of comfort for safety especially the face shields meant to e used in a potentially high infectious environment such as hospitals and labs, therefore, knowing the exact purpose of the face shield you are buying will play a key role in identifying the right face shield.
It is imperative to pick face shield that let insufficient light from both sides to give it a high transparency rate, therefore the material of the face shield need to have high optical clarity with minimal distortion. Viewing through a clear and better lens ensures your eyes do not strain and you can work longer with less fatigue and therefore less overall strain on your body, one of the materials that can be used to achieve this condition is PETG a short name of polyethylene terephthalate that is modified with glycol.
The other important feature you need to look at is the reusability of the face shield you are buying, you should be able to distinguish between reusable and disposable face shield, a disposable face shield is meant for one-time use and therefore, the raw material will be light and has a foam attached to the visor making them porous and difficult to clean, however, a reusable face shield is normally heavier and has a more rigid visor, formless and can be cleaned with ease for re-use. You can apply these pointers when buying face shields.
