Have you ever tried to look at your phone screen in the sunlight, only to be unable to discern the content due to strong reflections? These frustrating moments can certainly leave us feeling defeated. In modern life, electronic devices accompany us in everything we do, but glare often becomes one of the biggest obstacles to using these devices. Glare refers to the phenomenon where excessive light intensity, as well as factors such as the direction and reflection of light, lead to visual discomfort or reduced visual capacity. Glare can interfere with a person's ability to effectively observe their surroundings, causing eye strain, distraction, and even impacting safety.

The glare we experience in our daily lives includes natural light from the sun and reflected light, as well as light emitted from LED lamps, fluorescent lights, televisions, and phone screens. The glare caused by phone screens mainly arises from two factors:

• The high brightness of screens leads to increased reflected light, resulting in glare;
• Most screens have a smooth glass surface, which easily reflects external light sources, causing intense reflections.

How Does an Anti-Glare Screen Protector Really Work?

Light Scattering

The surface of an anti-glare screen protector is typically matte or frosted, which creates tiny textures that enable light to scatter uniformly when it hits the protector's surface. Compared to a smooth surface, a matte finish effectively prevents light from reflecting straight into the eyes.

Reduced Reflection

With special coatings, anti-glare films can minimize the reflective light on the screen surface. Compared to smooth surfaces, matte surfaces disperse light reflections more effectively, thus significantly reducing the intense reflections and, consequently, the impact of glare. For instance, PERFECTSIGHT utilizes Rare Earth Coating Technology that not only blocks at least 55% of blue light but also reduces glare by 55%.

Contrast Optimization

The combination of scattered light and reduced reflection intensity enhances the contrast between images and text displayed on the screen and their backgrounds. This makes content clearer and lessens the visual blur caused by bright lighting conditions.

Reduced Eye Fatigue

By minimizing brightness-related visual distractions, anti-glare screen protectors help maintain eye comfort during prolonged use of electronic devices, thereby reducing eye fatigue and discomfort.
