Guardian tempered glass is specially designed to protect your screen and privacy. It has a patented dust-free chamber for automatic adjustment and quick application. The 28° ultra-narrow privacy technology ensures that only you can see the contents of the screen, providing more extensive privacy. The anti-reflective coating improves clarity and protects the eyes. The reinforced glass with a high aluminum content provides impact resistance and prevents the edges from breaking. The vacuum-coated oleophobic layer resists oil and fingerprints for a smooth touch experience.
