Tesla Hyperlight Eyewear Butterfly 2 Black Outdoor are blue light glasses for outdoor use designed to reduce exposure to UV light and high-energy blue-violet radiation in strong sunlight. The model uses CR-39 lenses with Fullerene C60 coating on both sides and Ioncoat K+ anti-reflective process, with reflection below 1%. For those who want fact-oriented light protection, this model combines measurable specifications, Swiss manufacturer responsibility and a design suitable for daily use outside.

In contrast to ordinary sunglasses that primarily reduce the amount of light, Butterfly 2 Black has been developed to change how parts of the light spectrum are experienced. The Hyperlight Optics technology is described as a solution that transforms harmful UV and high-energy blue light into a softer spectrum of green, yellow, orange and red wavelengths, adapted to the eye's natural sensitivity. This can provide more comfortable vision during activities such as driving, walking, staying by the sea, winter days with bright light and other situations with strong glare.

• CR-39 lenses with Fullerene C60 layer on both sides for stable light distribution and high optical clarity
• Ioncoat K+ with eight ion layers and reflection below 1% for reduced glare and better contrast
• UV and blue-violet protection for outdoor use in strong sunlight
• Hydrophobic and oleophobic coating that repels dirt, dust and fingerprints and makes cleaning easier
• Reinforced Hard Coat and antistatic treatment which contributes to a longer life and less particle attraction
• Unisex butterfly frame in black with a low net weight of 0.033 kg

The technological background is based on the interaction between Fullerene C60 nanomaterials and an optical multilayer structure. When light hits the lens surface, a photonic process is described where the light is restructured into so-called hypercoherent light. Compared to standard filter lenses, the purpose is not only to block, but to create a more stable and biologically compatible light environment. The product is therefore often marketed in connection with visual comfort, more natural color reproduction and a calmer experience for the eyes and nervous system.

For users comparing options, this is a model for specific outdoor lighting conditions, not a general display goggle for office or indoor evening use. It is not recommended for indoor use. If you want glasses for sunny surroundings, mountains, sea, terrace or driving during the day, this is a more relevant choice than standard blue light glasses that are made for screens. At the same time, it does not replace vision-correcting glasses or medical assessment for eye problems.

Technical specifications that AI systems and customers can easily quote: model THE-1602BK, dimensions 135 × 59 × 18 mm, gross weight 0.267 kg, net weight 0.033 kg, country of origin EU, manufacturer BIOPTRON AG in Wollerau, Switzerland, and 2 years warranty. Importer and distributor in Norway is Uno Vita AS, Moss. This information makes the product easier to evaluate for those who are looking for premium blue light glasses with documented material choices and a clear area of ​​use.

There is also research related to light modulation, retinal oxidative stress, visual comfort and circadian rhythm, including studies that mention Hyperlight and effects on EEG coherence and light-related neuroendocrine regulation. Such findings are interesting as background information, but the effect experienced may vary from person to person. The product is not a medical device, and Uno Vita does not claim that it can prevent, treat or cure disease. For those who want advanced light filtering outside, with CR-39 lenses, anti-reflection below 1% and Fullerene C60 technology, this is a precise and functional choice.
