Synvy 4 Pack Anti Blue Light Screen Protector for Casio PRO TREK Smart WSD-F30

• What is Blue Light? Blue light refers to light with a wavelength of 400-500 nm. It is a type of visible light that is short and has high energy. This light can directly penetrate the lens and reach the retina of the eye. In the age of smartphones, people are spending more time staring at screens, which emit a significant amount of blue light. This can be harmful to the eyes, causing strain and fatigue, as well as potentially leading to skin issues and exacerbating myopia, ultimately disrupting normal sleep patterns.
