1.What is DxShield®?
Do you experience any of the difficulties below?
Wearing the equipment for many hours in medical situations causes eyestrain.
It is difficult to read characters and look at screens.
Light Reflection Interferes with Your Vision
Glare from the film disrupts your work.
Your glasses and face mask reflect on the shield.
The Shield Film Fogs Up
Moisture in exhaled breath sticks to the shield, fogging it up and blocking your view.
DxShield® is a film for medical eye shield with a highly transparent anti-reflection film. Clear vision for long period of time is crucial in medical settings, especially in operating theaters. This shield is ideal for the task.
Dexerials has developed this film for shields by applying anti-reflection technology used for LCD displays.

2.Features of DxShield®
DxShield® has an anti-reflection layer on both sides of the film. This anti-reflection layer features nano-level tiny convexes arranged on the surface, which can be seen under magnification. It is called a moth-eye structure because it resembles the surface of a moth's eyes.
Dexerials' moth-eye type anti-reflection film provides anti-reflectivity to displays in the field of electronics field. Dexerials Corporation has applied this technology for medical shield applications.
Low reflection / High transmission
DxShield film has convexes smaller than the wavelengths of visible light (380 to 780 nm) to make light reflection as low as possible.
Light reflection occurs between the air and a light-receiving substance that has a refractive index different to that of air. The refractive index of the moth-eye structure changes continuously so almost no light is reflected back to your eyes.

- * If the film surface is scratched or stained, it may not meet the above product characteristics.
Difficult to fog up
Fogging of the shield is caused by water vapor contained in exhaled air sticking to the shield surface as small water droplets.
Because DxShield® uses a hydrophilic resin to form the moth-eye structure, moisture attached to the surface does not spread or wet the surface quickly, making it difficult for the film to fog up.
This feature keeps the shield fog-free from the inside, providing a clear view during medical diagnosis and treatment.

3.Mitigating the fatigue from wearing eye shields
Protective eyewear such as eye shields increases medical safety by preventing medical professionals from experiencing droplet infection through the eyes. However, in practice, eye shields are not always used due to the discomfort of wearing them and the feeling of fatigue caused by the way they scatter light and obstruct one's view.
Compared to conventional eye shields, eye shields using moth-eye type films can reduce the eyes fatigue. We hope this will improve the rate at which medical professionals wear eye shields, thus increasing medical safety and making surgical rooms easier to work in.
