Blue cut lenses are specifically designed to filter or block a significant portion of blue light emitted from digital screens and artificial lighting while minimizing color distortion.
In more detail:
- Purpose: The primary function of blue cut lenses is to reduce the amount of blue light reaching the eyes.
- Blue Light Filtering: They selectively block most, but not all, blue light. This selective filtering aims to reduce potential eye strain and sleep disruption associated with prolonged exposure to blue light. Allowing some blue light through is important to avoid excessive color distortion.
- Color Perception: Quality blue cut lenses are engineered to minimize or eliminate color distortion, ensuring that the wearer perceives colors accurately. Cheaper versions may noticeably tint everything yellow or orange.
- Contrast with Anti-Glare Lenses: Unlike anti-glare lenses, which reduce reflections and glare, blue cut lenses directly address the blue light spectrum. Anti-glare lenses do not block any specific wavelengths of light.
In essence, blue cut lenses are a type of eyewear designed to selectively filter blue light, aiming to reduce its potential negative effects on vision and sleep patterns while maintaining accurate color perception.
