BLUVERRA® A journey with light

Besides being an adventure, traveling across time zones is also a challenge for both body and mind. Every time shift (even switching to daylight saving time), shift work, or missing regular sleep changes the way our bodies function. At the center of this change lies one key factor: light.

Just imagine traveling without exhausting jet lag, without insomnia, and without losing days to adapt.

Imagine your internal clock staying in perfect harmony with the world around you while you travel.

Welcome to BLUVERRA®. Glasses with sophisticated design and advanced NEURAOPTICS® technology based on years of scientific research on the negative effects of blue light on the body. BLUVERRA® glasses successfully harmonize circadian rhythms and prevent jet lag.

Control the light and control the time

Jet lag occurs when our circadian rhythm, our natural sleep-wake cycle, becomes disrupted due to travel, changes in sleeping patterns, or even too much screen exposure.

At the core of this mechanism is blue light, the part of the spectrum that most strongly affects sleep, acting through the internal biological clock in the brain — the suprachiasmatic nucleus (SCN). It regulates the release of melatonin, the hormone that tells us it's time to rest and sleep.

During travel across global time zones, our internal and external rhythms may fall out of sync. The brain continues to follow previous patterns, leading to classic jet lag symptoms: insomnia, headaches, fatigue, and reduced concentration.

Bluverra Science – Optical precision for biological balance

Bluverra glasses are more than a popular fashion accessory. They are the result of optometric engineering and biological expertise, designed to act at the very source of the issue – the light spectrum that influences the body's rhythm.

Their bio-optimized NEURAOPTICS® technology filters wavelengths of blue light that most inhibit melatonin secretion, allowing the body to naturally recognize “night.” In this way, in addition to all other positive effects, Bluverra® supports optimal melatonin production and speeds up the adaptation process to a new time zone.

Three levels of Bluverra lens action

  1. Melatonin regulation
    By reducing exposure to blue light in the evening, Bluverra enables a physiological rise in melatonin. The body more quickly “understands” that it is time to rest, making it easier to fall asleep and reducing nighttime wakefulness — even in the first days after arriving in a new time zone.
  2. Faster circadian rhythm adjustment
    Controlling light stimuli through blue spectrum filtration helps shorten jet lag duration and reduce symptom intensity. We achieve more stable sleep, better concentration, and more daytime energy.
  3. Vision protection and reduced digital fatigue
    Beyond its impact on the sleep hormone, Bluverra glasses reduce eye strain and digital fatigue — a common issue for travelers spending hours in front of screens or under artificial lighting during flights or work.

Bluverra Experience – Science you can wear

Imagine that after a long flight into a new time zone, your body and mind remain clear, rested, and synchronized. That sleep comes easily, and the day begins without drowsiness or fatigue.
Bluverra glasses provide precisely this biological stability through optical intelligence. Each pair is the result of combining modern design, medical knowledge, and technology that respects the body’s natural rhythm.

Who are Bluverra glasses for?

  • Frequent travelers and business people who cross multiple time zones and wish to reduce jet lag effects
  • Pilots and cabin crew whose sleep rhythm suffers due to changing time zones and lighting conditions
  • Digital nomads and professionals who work long hours in front of screens, regardless of location
  • Anyone who wants healthy sleep, clear focus, and a balanced biological rhythm

Bluverra glasses are not just blue-light protection. They are an investment in health, regeneration, and cognitive efficiency.

Balanced melatonin means better sleep. Better sleep means more energy, better memory, and a more stable mood. With all of this, we achieve better performance in every time zone.

For those who don’t want light to slow them down. For those who want to travel smarter, work clearer, and sleep more peacefully.

Welcome to Bluverra: the science of light, transformed into everyday protection.

Zašto su Vam potrebne naočare za plavu svetlost?

Why do you need blue light glasses?

We all know that using your phone before bed is a bad habit. However, few understand that the problem isn’t just the phone. Late use of computers, watching TV, or even regular home lighting can be the main reasons why you wake up tired and “broken” in the morning. In this blog, you will learn how artificial lighting affects your body and how BLUVERRA glasses using NEURAOPTICS technology can transform your health and energy levels. How does blue light block melatonin? When we are exposed to artificial light at night, our brain receives the signal that it is still daytime. As a result, the brain stops producing melatonin—the hormone crucial for initiating sleep and body regeneration (also known as an anti-aging molecule). Without melatonin, our body cannot enter deep, restorative sleep. Even if you manage to fall asleep, that sleep won’t be of high enough quality for your body and mind to fully recover. Why is the light spectrum important? The problem lies in the frequencies of blue light. These frequencies dominate all modern LED screens and bulbs. They are the same frequencies found in sunlight that our internal (circadian) clock uses to know when we should be awake and when we should rest and repair damaged cells. The connection between sleep, mitochondria, and your health Sleep is the time when your body performs “maintenance” at the cellular level. During sleep, we repair our mitochondria, the small powerhouses in our cells that convert food into energy. When we are young, our mitochondria work excellently (we call this a "fast metabolism"). As we age, their function declines, but this process accelerates drastically if we don’t sleep well. Leading experts agree: the most common cause of poor sleep in the modern world is excessive exposure to artificial light at night, which leads to: Obesity and metabolic disorders Anxiety and depression Heart disease and neurodegenerative issues BLUVERRA solution: NEURA DEFUSE and NEURA NIGHT Fortunately, you don’t have to live in darkness to protect your health. BLUVERRA offers science-based solutions tailored to your daily rhythm. 1. NEURA DEFUSE: Protection during the workday Our NEURA DEFUSE lenses are designed for daytime use. While most regular computer glasses block barely 3% of harmful spectrum, NEURA DEFUSE uses specific pigments that block 95-100% of the most harmful peak blue light (455nm). Use: Office, school, stores, and computer work. Benefit: Reduces eye strain and prevents headaches. 2. NEURA NIGHT: Maximum recovery after sunset When the sun sets, you need full blocking. NEURA NIGHT lenses block all blue and most green frequencies (up to 550nm). Use: As soon as artificial lights turn on at home or after sunset. Benefit: Signals the brain that it’s time to rest, allowing deep and quality sleep. Frequently Asked Questions (FAQ) Are “Night Shift” modes on phones enough? While these modes are a step in the right direction, they are insufficient. Software-based blue light reduction is minimal and does not protect you from home LED lighting or TV screens. NEURA NIGHT glasses provide a physical barrier that blocks the entire harmful spectrum from all sources. Why are NEURA DEFUSE glasses yellow and not clear? Clear lenses physically cannot block the harmful 455 nm peak. The yellow color of our lenses comes from specific pigments that are the only ones able to provide full protection. Clear glasses are often just a marketing trick that blocks less than 3% of harmful light. Can I wear blue light glasses all day? NEURA DEFUSE is ideal for all-day indoor use. However, we recommend not wearing them in the morning while outdoors in direct sunlight, as full-spectrum natural light is necessary for your hormonal balance. Light and darkness: The key to maximum results Glasses alone are not a magic solution if you completely ignore nature. Melatonin is created through interaction with UV light and our eyes during the day. Watch the sunrise: This is the “reset” button for your internal clock. Don’t wear glasses in the sun: Sunglasses block signals your body needs. Avoid contact lenses: They block oxygen to the cornea, directly weakening your mitochondria. As Benjamin Franklin said: "Early to bed and early to rise makes a man healthy, wealthy, and wise." Your health begins with the light you surround yourself with. Protect your eyes, sleep, and mitochondria with NEURAOPTICS technology. Your body will thank you. View the complete NEURA lens collection and choose your pair. ```

Pariz pod plavim svetlom: Grad svetlosti koji nikada ne spava

Paris under blue light: The city of light that never sleeps

Paris has always been a city that shines even when everyone else sleeps. From the golden glow of the Eiffel Tower to the reflections on the surface of the Seine, light is its signature. Back in the 19th century, it became known as the "City of Light" for being one of the first European capitals to introduce gas street lighting. Today, in the 21st century, that symbol of modernity is taking on a new, cooler shade — blue. Blue light, the high-frequency and high-energy part of the spectrum between 380 and 500 nanometers, naturally comes from the Sun, giving the sky its blue appearance. However, with the development of technology and modern urban living, humans have become exposed to an entirely new, artificial source of this radiation. LED diodes, screens, neon signs, and modern facades lit with cool tones have become a part of everyday life. Paris, once glowing warmly in golden tones, now in many areas shines cold blue at night. This visual aesthetic symbolizes technological progress, but also raises the question of how this change affects us. Biological clock in the era of artificial light The human body has evolved for millions of years in accordance with natural day-night cycles. Our circadian rhythm, that internal biological clock, aligns physiological processes with the alternation of light and darkness. When the sun sets, the reduction of light stimulation naturally triggers the release of melatonin — the hormone that signals the body it is time to rest. In modern cities like Paris, where the lights never go out, this ancient rhythm becomes disrupted. Blue light has a unique ability to affect special cells in the retina that are not used for vision, but only to measure the amount of light in the environment. They send signals directly to the part of the brain responsible for our biological clock. Exposure to blue light in the evening practically "tricks" the brain into believing it's still daytime. Melatonin release is delayed, sleep is postponed, and the consequences go beyond simple insomnia — chronic fatigue, weakened immunity, and metabolic imbalance occur. Paris becomes a symbol of the modern paradox: the desire for eternal activity in an environment that has forgotten darkness. Eyes under high-energy exposure On the level of the eye itself, the problem is physical. Blue light penetrates deeper into the structure of the eye, and its high energy can cause oxidative stress that damages cells. Particularly sensitive are the parts of the retina responsible for central vision and color perception. Although our eyes have natural defense mechanisms and antioxidants, they were not designed for constant, chronic exposure to artificial sources. When these resources become exhausted, permanent changes may occur, and scientific research increasingly links intensive blue light exposure with accelerated development of macular degeneration. A thin line between medicine and harm Still, it is important to remember that blue light is not exclusively an enemy. Its nature is dual. In medicine, it is successfully used, for example, in the treatment of jaundice in newborns or for accelerating tissue regeneration. A similar balance applies to everyday life — natural daylight, rich in blue spectrum, is essential for wakefulness, concentration, and good mood. The problem begins when that spectrum carries into the night. While it helps us function during the day, screens and LED lighting at night lead to digital fatigue and sleep disruption. Paris as a mirror of modern life Observing Paris at night reveals a mesmerizing sight. Bridges, streets, and monuments shine brightly. But behind that spectacle lies a change in lifestyle. Urban residents spend most of their time indoors, often under artificial lighting that disrupts natural balance. In Paris, where nightlife is part of cultural identity, the line between day and night becomes blurred. Studies in such urban environments show a clear correlation between light pollution and increased anxiety, cardiovascular problems, and depression. Our body has an incredible capacity for adaptation, but the hormonal system — from cortisol to serotonin — depends on a clear signal of when to be awake and when to sleep. Prolonged exposure to blue light at night creates neurohormonal confusion that affects not only the body, but also the mind. Between light and darkness Blue light has become a symbol of the rhythm of modern life: it boosts alertness and productivity, yet disturbs natural balance. Paris, as a global capital of culture and technology, perfectly reflects this duality — a city powered by its light, but one that must learn how to manage it. The solution is not darkness, but conscious use of technology. More natural light during the day, and warmer, dimmed lighting at night help the body return to balance. The phenomenon of blue light goes beyond medicine — it is a matter of lifestyle. To the extent that we learn to use light consciously, respecting biological rhythms, we can enjoy its beauty and the advantages of modern times without compromising what makes us human — our unbreakable connection with natural time.

Digitalni umor i vizuelni sindrom

Digital fatigue and visual syndrome

Digital fatigue is a complex functional disorder that occurs as a result of prolonged and intense exposure to screens. It is a multifactorial syndrome affecting the visual apparatus, oculomotor system, visual processing in the cortex, as well as neuroendocrine mechanisms regulating the circadian rhythm. Modern lifestyle, while it greatly facilitates work, also leads to the development of new professional problems. Additionally, computer use and high-energy LED lighting have contributed to digital fatigue becoming one of the most common subclinical conditions today. Modern screens emit light with a pronounced component of the short-wavelength visible spectrum (around 450 nm). Although these wavelengths are not “harmful” in the classical UV-radiation sense, they possess properties that accelerate visual fatigue. Short-wavelength blue light undergoes Rayleigh scattering, leading to increased intraretinal diffusion of light signals, reduced contrast sensitivity, and faster onset of visual confusion during long screen use. This effect becomes more pronounced during prolonged monitor work, especially in dim lighting. Increased accommodation effort is another key factor causing accelerated fatigue. High contrast of bright screen backgrounds, combined with short-term flicker modulation, results in faster ciliary muscle fatigue, increased accommodation spasm, and blurred vision. Biologically, the blue component specifically stimulates intrinsically photosensitive retinal ganglion cells (ipRGCs), which influence melatonin suppression and circadian rhythm shifting. This is the key reason why digital fatigue has systemic consequences, not only local ocular symptoms. Visual-ergonomic factors and symptoms During screen work, blinking frequency drops from an average of 15–17/min to only 5–7/min, which is a key mechanism behind dry eye. Additionally, Near-vision lock (visual lock-in), a phenomenon where prolonged near-focus causes muscle spasm and so-called pseudomyopia, is present. The most common symptoms indicating digital fatigue are: Ocular symptoms: Blurred vision after prolonged work, sensation of sand or foreign body in the eyes, dry eyes, redness, and a burning feeling. Neurological and painful symptoms: Headaches (especially frontal and supraorbital) and difficulty concentrating. Functional issues: Slower refocusing when looking into the distance, sleep disturbance, and nighttime insomnia. In children and adolescents: Poor posture, reduced attention span, and increased irritability are often present. Recommendations and expert advice There are several expert strategies that can reduce discomfort and prevent long-term consequences: Accommodation hygiene: Apply the “20-20-20” rule — every 20 minutes, look at a distant object (over 6 meters) for 20 seconds. This reduces accommodation stress and the risk of muscle spasm. Tear film stabilization: Conscious and regular blinking is key. If needed, use preservative-free lubricating eye drops (artificial tears) and avoid direct airflow (AC) to the eyes. Optimal ergonomics: Lighting color temperature should be 2700–3500 K in the evening. Place the monitor 15–20° below the horizontal line of sight to reduce eyelid opening and dryness. Eliminate reflections from windows and lighting sources. Blue light protection: When screen use cannot be avoided at night, use optical aids (glasses) or software filters that block high-energy wavelengths (≈ 420–455 nm) to stabilize circadian rhythm. Multitasking reduction: Limit rapid switching between multiple screens (phone, laptop, tablet) as it creates unexpectedly high cognitive and visual load.
