In today’s modern world, we spend countless hours in front of screens—phones, computers, and TVs. But what seems like a harmless habit may be silently disrupting the quality of our sleep. The culprit? Blue light—a type of light surrounding us more than we realize.

What is blue light?

Blue light is a high-energy, short-wavelength light (about 400–500 nm) that naturally exists in sunlight, helping regulate alertness and the body’s circadian rhythm. However, artificial blue light—emitted from screens, LED lights, and fluorescent lamps—can be harmful, especially during the evening and night.

Negative effects of blue light on health

Blue light’s biggest danger is its ability to suppress melatonin, the hormone responsible for making you feel sleepy and relaxed. When exposed to blue light at night, your brain is tricked into thinking it's still daytime, delaying melatonin production. This leads to:

  • Difficulty falling asleep or staying asleep

  • Daytime fatigue and poor concentration

  • Disrupted circadian rhythm

  • Long-term risks to mental health and immunity

A Harvard study found that exposure to blue light before bed can delay melatonin production by up to 90 minutes and reduce REM sleep duration—the deep, restorative stage of sleep.

Who is most vulnerable to blue light exposure?

  • Night-shift workers constantly exposed to screens and artificial light

  • Students and children, whose developing brains are highly sensitive to circadian disruptions

  • Older adults, who already struggle with sleep

  • Anyone using devices before bed—a widespread habit today

How to reduce blue light’s harmful effects

To protect your sleep and overall health, try implementing the following habits:

  • Limit device use 1–2 hours before bedtime

  • Enable Night Shift or Night Light mode on your screens

  • Use warm-colored night lights instead of bright LEDs

  • Maintain a consistent sleep schedule

  • Use blue light blocking glasses

This last method is highly recommended by sleep experts. These glasses filter harmful wavelengths before they affect your eyes and brain, helping your body maintain its natural sleep-wake cycle.

VivaRays: Blue Light Glasses Designed for Each Time of Day

Not all blue light glasses are created equal. Many claim to reduce digital eye strain, but very few are designed with the body’s natural circadian rhythm in mind. Most simply block a portion of blue light, regardless of the time of day or your biological needs. That’s where VivaRays truly stands out—by offering a science-backed, time-specific solution that works in harmony with your body’s internal clock.

VivaRays has developed a unique three-tier system that addresses your light exposure needs across the entire day, helping you stay energized when needed and wind down naturally when it’s time to rest.

1. Daytime Yellow Glasses: Stay Focused Without Fatigue

During the day—especially in indoor environments filled with artificial lighting and digital screens—our eyes are bombarded with intense blue light. VivaRays' Daytime Yellow Glasses are designed to filter out the most disruptive wavelengths of high-energy visible (HEV) light while still allowing enough natural light to promote alertness.

Wearing these glasses can:

  • Reduce computer-related eye strain and visual fatigue

  • Improve focus and cognitive clarity, especially during long work sessions

  • Support stable mood and energy levels

  • Lower your risk of developing digital eye strain or “computer vision syndrome”

These lenses are ideal for office workers, remote professionals, students, and anyone spending more than 2–3 hours a day on screens.

2. Evening Orange Glasses: Shift from Activity to Recovery

As the day winds down, our body should start producing melatonin to prepare for sleep. But exposure to screens, LED lights, and even bright overhead lighting can prevent that process. VivaRays' Evening Orange Glasses block out more than 90% of blue and green light—two wavelengths known to suppress melatonin and overstimulate the nervous system.

Benefits include:

  • Helping the brain shift from a “thinking” mode to a “rest and digest” mode

  • Lowering cortisol levels and reducing mental tension

  • Promoting earlier melatonin release so you can fall asleep naturally

  • Supporting better emotional regulation and relaxation in the evening

These are perfect for wearing after sunset, during dinner, while reading or watching TV, and during your bedtime routine.

3. Nighttime Red Glasses: Maximize Deep, Restful Sleep

The final piece in the VivaRays system is the Nighttime Red Glasses, which block 100% of blue light and a significant portion of green light. These glasses are designed for use in the final hour or two before bed. They simulate the lighting conditions of a pre-electricity environment—dark and warm-toned—signaling to your body that it's time to sleep.

With regular use, users report:

  • Falling asleep faster and waking up less frequently at night

  • Improved sleep depth and vivid dreams (a sign of more REM and deep sleep)

  • Enhanced morning alertness and reduced “sleep inertia”

  • Stabilized circadian rhythm, even for shift workers or frequent travelers

If you're someone who wakes up feeling groggy despite sleeping 7–8 hours, this tool might be the missing link in your sleep strategy.

Flexible Solutions for Real Life

In addition to individual pairs, VivaRays offers 2-in-1 and 3-in-1 modular systems. These allow you to swap lenses throughout the day using a magnetic clip-on design—no need to carry multiple glasses or guess which one to wear. It’s perfect for people on the go, parents juggling routines, or anyone who values convenience and simplicity.

Why Choose VivaRays Over Other Blue Light Glasses?

Here’s how VivaRays sets itself apart from typical mass-produced blue light glasses:

  • Scientifically engineered to support your natural hormonal rhythms, not just your screen comfort

  • Eco-friendly materials, including FSC-certified wood frames and non-toxic lens coatings

  • Exceptional comfort for extended wear—lightweight frames with ergonomic nose pads

  • Endorsed by leading biohackers, doctors, and wellness coaches

  • 90-day risk-free trial, so you can test the difference without pressure

With thousands of positive reviews and a growing community of sleep-conscious users, VivaRays isn’t just a product—it’s a lifestyle upgrade backed by science.

Conclusion: Sleep is the Foundation of Health

We can't completely eliminate blue light from our lives, but we can take control of our exposure through small, effective changes. Managing screen time, adjusting lighting, and using the right tools can help restore energy, improve sleep, and boost overall well-being.

Don’t wait until sleepless nights take a toll on your life. Start protecting yourself and your loved ones—begin with your sleep.

If you're looking for an easy, effective, and trusted solution, blue light blocking glasses from VivaRays are worth considering. Sometimes, a simple shift like this can lead to major improvements in your health and quality of life.
