There are many face shields on the market for use by health workers, but most have limitations:
Face shields can be heavy, expensive and difficult to adjust
Condensation forms on the visor, especially when wearing a mask
Visors cannot be lifted to allow direct vision
Most shields do not have any lighting system to help vision
Some face shields with lighting have wires to the power supply that often is worn on a belt
The wearer often finds wearing a shield is uncomfortable due to heat build up
The visor often splays outwards toward to the chin and are too long
This device has the following benefits:
Comfortable to wear with a rotating dial ratchet system that allows movement of the overhead and around head headbands
Light weigh- under 263g (including the headband). Weight is supported efficiently with vertical headband support. Some face shields weigh over 400g.
Two superbright cool white LEDs with a narrow beam angle; this allows excellent vision. The two LEDs stick out from the visor to allow easy movement (up, down, left and right) to allow focus of the beams. The LEDs cannot be rotated but can be retracted into the housing when not in use
Virtually silent mini fan that cools the face and reduces condensation
Two micro switches that allow on/off control of LEDs and fan
Internal power supply- that lasts for over fifteen hours with continuous use of LEDs and fan. The batteries are easily replaceable and rechargeable
Micro USB port on the unit to allow recharge or “on the go” recharge and use if plugged into a 5V power supply or power bank via USB
Charging and charged LED light; battery indicator to show remaining power capacity
Visors are cheap, easily replaced and coated with anti-fog film
Visor can be easily moved upwards to allow direct vision
Fan can be used for 30,000 hours. LED can be used for 50,000 hours
Side support to prevent splaying of visor and wrap around protection
To reduce weight, the internal batteries may be removed and the device powered by a mobile phone power bank.
Filtration of intake ventilation air using a piece of a surgical face mask, ideally a Level 3 type. This prevents aerosols contaminating the operator’s eyes. Level 3 masks consist of an outer fluid resistant layer, a middle anti-microbial layer and inner layer for soaking up sweat. Only the first two layers are used, so that air intake through the shield is efficient. Users can replace the filter easily or choose not to have a filter if no risk of aerosols.
Can be worn with loupes and face mask. Please note that loupes may still get condensation; fan will only help reduce condensation of the visor.
The front of the face shield housing in Version 1B has a small loupe light holder to allow the user to attach his/her own loupe headlight and use his/her own power supply.
Version 2 of the face shield has an ultrabright, dimmable, integral loupe headlight. This can be used wirelessly for some time using the internal batteries or wired using a power bank. Version 2 has an integral battery charging and battery capacity indictor.
