Blue light is everywhere.
Your computer screen, phone, tablet and even LED lights in offices and homes.
Just as commonly known UV light, high energy blue light also causes strain and damages to the eye as well as other complications.
Traditional blue light blockers simply introduce a yellow tint that do not discriminate in the blue light spectrum. A unnecessary high block percentage causes color distortion and other undesirable effects. Le Seven lenses target mostly the high energy density blue lights which is a much more effective mechanism and eliminates any side effects.
GETTING TO KNOW ABOUT BLUE LIGHT
The Inevitable Exposure to Blue Light
Blue light is part of the visible light spectrum and is emitted by daylight, LED lighting, and digital screens. Le Seven blue-light-filtering lenses filter 25% of blue light while helping maintain natural color perception.
Blue Light Can Be Harmful
Blue light is a part of the visible light spectrum, with a wavelength between 380nm and 495nm. It reaches deeper into the eye compare to UV lights, and its cumulative effect can cause damage to the retina. Certain wavelength of blue light also leads to implications in the development of age-related macular degeneration (AMD).

Blue light is a part of the visible light spectrum, with a wavelength between 380nm and 495nm. It reaches deeper into the eye compare to UV lights, and its cumulative effect can cause damage to the retina. Certain wavelength of blue light also leads to implications in the development of age-related macular degeneration (AMD).
Traditional Blue Light Blocker
The traditional blue blockers do not discriminate in the blue light spectrum. They simply block all the blue light by introducing a yellow color tint. This blocking mechanism is less efficient, and also blocks beneficial blue light causing color distortion.
Le Seven Blue Light Blocker
Not all blue light is harmful. Filtering too much blue light by simply introducing a yellow tint causes color distortion.
Le Seven lenses are clear lenses with a special coating that targets only high energy blue lights. It allows the beneficial visible light, including the blue-turquoise light, to pass through. This allows the lenses to have excellent light transmittance with no color distortion and the best possible clarity.
Le Seven Screen Material & Coating
Le Seven lenses are designed for impact resistance, lightness, and a thin profile.
Every Le Seven lens option includes scratch-, impact-, and glare-resistant coatings as standard.
