I would offer this is the only company I will do business with regarding Class 4 Laser safety. Their service is second to none. Regarding the acrylic face shield only, and its protection, this is absolute. The hardware metal screws are of a poor grade and sheared in half. The controls to elevate the face shield, will not properly hold the face shield elevated, and all plastic components, excepting the acrylic face shield, component plastic used, is some sort of possible styrene and not acceptable for this application . I wear their CE protective goggles in the 445 NM in the event the unit fails, and if you do, the face shield has merit in Class 4.

How long a prism is needed depends upon your individual needs and your eye condition. Sometimes a prism is needed for several months, but the strength of it changes as your eye condition stabilises.

This leaflet has been given to you by your orthoptist, who has suggested that a fresnel prism may be the best treatment for you at this stage.

A fresnel prism is a thin transparent plastic sheet which induces a prismatic effect (it alters the direction of the image entering the eye). One side has a series of angular grooves (prisms), and the other smooth side is attached to the lens of your glasses.

Expect excellent service and certifications sent on each pair of specific lenses to the end user client. You cannot get a second chance with high intensity lasers and your eyes. I absolutely trust this firms product, their certifications and their excellent service.

Please note that our face shield design is functionally similar to those available from industry leaders like Pyramex, Grainger, 3M, or at hardware stores, differing primarily in the addition of the laser safety component, which is our unique value proposition.

You do not usually need to remove the prism from your glasses to clean it, just wipe it with a lens cloth. If the fresnel prism becomes dirty it can be removed and cleaned with a soft toothbrush and soapy water and reapplied.

A prism is a wedge-shaped piece of glass or other transparent material, which deflects rays of light toward the base. It is routinely used in orthoptic practice to measure the size of a squint (how much the eye turns in or out) and can be used to redirect the rays of light onto the correct point of the back of the eye.
