Blue light protect lenses filter out a portion of blue light emitted from digital devices like computers, smartphones, and tablets. : Sunlight naturally emits blue light, which plays a role in regulating our sleep-wake cycle. However, digital devices also emit a significant amount of blue light, particularly in the high-energy range. • Potential Effects: There's ongoing research about the long-term effects of blue light exposure from digital devices. Some studies suggest it can contribute to eye strain, fatigue, and disruptions in sleep patterns. • Blue Light Filtering: Blue light protect lenses contain a special coating that absorbs or reflects some of the blue light, particularly in the high-energy range. This aims to potentially reduce the discomfort associated with prolonged screen time.
