9H Hardness - Screen Patrol's top layer takes scratch-resistance to a new level. With a 9H hardness rating, Screen Patrol cannot be scratched by knives, let alone your house keys.
Responsive Screen - Screen Patrol maintains your original touch experience with a barely-there thickness of 0.33 mm. Plus, this also means you can see your screen like it was meant to be seen.
No More Fingerprints - The oleophobic coating keeps fingerprints off your screen by repelling any and all oils. Cleaning your screen just got way easier.
Blue Light Protection - Exposure to shortwave blue light from LEDs for long periods of time can throw off your sleep cycle, and worse, it can strain or damage your eyes. Screen Patrol's Anti-Blue Light technology reduces the intensity and strength of shortwave blue light by over 50 percent, protecting your vision.
For Samsung Galaxy S4 Only
Protect your eyes with Caseco Screen Patrol. Screen Patrol is Caseco's newest offering designed to protect you from high-energy blue light. High-energy blue light is produced by all displays and causes tired eyes, loss of sleep, and potentially eye damage. What kind of displays produce harmful blue light? All devices with screens produce harmful blue light. LED displays produce high-energy blue light, as shown in the picture. Even devices without LED displays like the iPhone, for example, are still using an LED backlight to provide that crisp, clean white look that iPhone users love. This means that Screen Patrol is beneficial no matter what kind of device you use.
