We have had many requests for advice, support, files, etc from schools who are making visors to help protect the NHS and other medical and care workers through the COVID-19 pandemic.
General Advice from the Design and Technology Association
There is a demand for a large quantity of visors to be used in conjunction with face masks to help protect medical staff from COVID-19. This is not intended to be used in place of a surgical visor, but where the alternative would be no visor at all. The visor can take the form of a disposable item or with the right processing between uses can be reusable or could have a reusable section with a disposable screen. The visor will in most cases be used for a period of four hours at a time so some consideration should be given to the comfort of the device. The visor should be held slightly away from the face to accommodate a face mask and the possibility of prescription glasses, and to reduce fogging due to breathing on the item. If possible, the visor should provide protection between the top of the product and the forehead of the wearer. The size of the visor should be no smaller than A4, covering ear to ear and extending below the mouth. The shape must not splay out at the bottom and be rounded to prevent it digging into the body.
School's are typically using their Laser Cutters and/or 3D Printers to manufacture the visors.
