Fulton Sunset

[red tinted sunset lenses]

Iconic square frames perfect for round faces - by adding definition, heart-shaped faces - by balancing proportions and oval faces - by complementing. Equipped with sunset lenses that block almost 100% of blue & green light (depends on lenses option) to help you fall asleep instantly.

Frame:

Named after the historic Fulton Street in New York City, these bold frames capture the vibrant energy and architectural edge of downtown Manhattan. Just as Fulton Street has evolved from a maritime hub to a bustling commercial center, our Fulton frames blend classic structure with modern flair.

The substantial square silhouette offers a confident presence, crafted with premium materials, including durable & sustainable bio-acetate front paired with natural wood temples and precision hinges, the Fulton delivers both statement style and everyday wearability.

Perfect for the urban explorer or the fashion-forward trendsetter who appreciates design with a story behind it.

Lenses:

For red lenses Fulton Sunset offers three options: Standard 550, Premium 550, Premium 530. Wearing them 2 - 3 hours before bedtime makes you fall asleep instantly. By blocking the spectrum, it supports the production of melatonin, the sleep. Lenses are superior to competitors, by offering double sided anti-reflex coating to cover you also from blue and green light coming from your backs

Standard 550 lenses - the sleep preparation tool. The Standard Red lens is almost monochromatic—99.7% color purity means you're seeing almost exclusively pure red light. At 1,000K CCT, this approaches the warmth of an old incandescent bulb or candlelight. This is the maximum circadian protection. Your brain receives almost zero blue light signals, making melatonin suppression nearly impossible. The spectral output is radically simplified: red dominates completely, and blues and greens are essentially eliminated. Trade-off: With 80% light reduction and an Ra of 42, this lens transforms your visual world. You lose significant color information—reds remain vivid, but other colors become indistinct. Reading is possible but requires conscious effort. This isn't a lens for detailed work or color-critical tasks. Best For: Late-night wind-down routines, reading before bed, situations where maximum sleep preparation is the priority over visual acuity.

Premium 550 lenses - the evening guardian. The spectral analysis shows that they aggressively suppresses the blue and green peaks. Your eyes receive predominantly red wavelengths, with virtually no blue content. This is powerful for evening use and maximizes circadian benefits. Trade-off: At 69% light reduction, you'll notice a darker screen. Text becomes slightly more effortful to read, and colors shift dramatically. The Color Rendering Index drops to 51—meaning color accuracy suffers significantly. This is the choice for evening relaxation, not detailed work. Best For: Evening browsing, winding down after work, reducing melatonin suppression when you need to sleep soon.

Premium 530 lenses - the smart choice. They split the difference, it's still powerfully protective but maintains more usability. At 1,763K, office lighting takes on a warm amber-orange cast, similar to late sunset lighting. You're still dramatically reducing blue light exposure, but with better visibility for practical tasks. The spectral data shows a cleaner filtration profile. While red dominates (61.96%), you retain some green and amber spectrum, which helps with screen legibility and color perception. The Color Rendering Index of 58 is moderate—good enough for most evening activities, though still noticeably warmer than neutral. The 65% light reduction means your monitor appears dimmer, but this is often an advantage: you're naturally reducing overall eye strain while simultaneously cutting blue light. Best For: Evening work sessions, video calls after sunset, extended computer use without sacrificing too much visual information.

For prescription lenses, we need to know your exact eye correction measurements. After concluding your purchase, our team will get back to you with the request to provide us with the correct pupillary distance (PD), power range, and cylinder measurements.

Fulton glasses are packed with cork case, soft fabric case, soft cloth, tons of positive feelings and zero harmful plastics.

Each pair of glasses and lenses are assembled/finished in our manufactory in Slovakia, EU.
