Blue Blocking Glasses

Blue light blockers aid in improving sleep by addressing the disruptive influence of blue light on our body's natural sleep-wake cycle.

Here's how they work scientifically:

Our sleep patterns are governed by an internal biological clock known as the circadian rhythm.

This rhythm is highly sensitive to environmental light, particularly the blue light spectrum that is abundant in sunlight and also emitted by screens and artificial lighting.

Exposure to blue light, especially in the evening, can trick your brain into thinking it's still daytime, leading to suppressed production of melatonin, the hormone responsible for signaling sleepiness.

Blue light blockers function by filtering out this specific spectrum of light.

When you wear these glasses, especially in the hours leading up to bedtime, they reduce your exposure to blue light.

This allows your body to produce melatonin at a natural rate, helping to cue your body that it's time to wind down and prepare for sleep.

In essence, blue light blockers work like a dimmer switch for your brain's perception of light, gradually preparing your body for rest.

By reducing the interference with your circadian rhythm, these glasses can help promote a more natural sleep pattern, leading to better sleep quality and overall health.

Yes, blue light blockers can also be effective in reducing digital eye strain.

Here's the science behind it:

Digital eye strain, sometimes known as computer vision syndrome, results from prolonged exposure to screens.

This exposure leads to various symptoms like eye fatigue, dryness, blurred vision, and headaches.

One of the main culprits behind these symptoms is blue light.

Blue light from digital devices has a high energy level, which can cause more flicker and glare compared to other wavelengths.

This flicker and glare can reduce visual contrast, affecting sharpness and clarity, and leading to eye strain.

Our eyes also have to work harder to focus on the high-energy, short-wavelength blue light, contributing to the strain.

Blue light blockers help mitigate these issues by filtering out a significant portion of this problematic blue light.

By doing so, they reduce the flicker and glare, providing a more comfortable visual experience.

This reduction in blue light exposure can alleviate the symptoms of digital eye strain, making it easier to focus and reducing the overall stress on your eyes during prolonged screen use.

In summary, by minimizing exposure to blue light, these glasses help create a more visually ergonomic environment for your eyes, which can lessen the strain and discomfort associated with extended screen time.

The difference between Yellow (DayPro) and Red (NightPro) lenses in blue light blockers lies in their specific filtering capabilities and intended usage times.

1. DayPro (Yellow) Lenses:

These lenses are designed to filter out 95% of the blue light spectrum.

They're less intense compared to red lenses, making them suitable for daytime use, especially when indoors or working on screens. 

We recommend wearing DayPro lenses from around 2:30 PM onwards if you're going to be indoors and using screens.

This timing aligns with the natural increase in blue light exposure from screens and artificial lighting as the day progresses.

It's important to take regular breaks from screens and, if possible, go outside to receive natural light.

Natural light exposure is crucial for maintaining a healthy circadian rhythm.

When going outside, it’s advisable to take off your DayPro lenses to allow natural light to reach your eyes, which is beneficial for your internal body clock.

2. NightPro (Red) Lenses:

NightPro lenses are designed to block 100% of blue and green light.

This comprehensive blocking makes them more effective in preparing your body for sleep.

These lenses should ideally be worn after dark or 2-3 hours before your bedtime.

The complete blockage of blue and green light helps in the natural production of melatonin, facilitating a smoother transition to sleep.

It is not recommended to wear red lenses during the day, as this can disrupt your natural circadian rhythm and make you feel sleepy, when you're supposed to be alert.

When choosing the right blockers for you, it's important to know that all our glasses offer the same level of protection, as the lens quality is uniform across our products.

The primary difference lies in the frame material, which affects the price of each pair.

Here's how to choose based on your needs:

• If you work on screens all day, our DayPro (yellow) blockers are ideal. They're designed to reduce blue light exposure, making them perfect for daytime use and extended periods of screen time.

• For those who have trouble sleeping, especially after screen use at night, our NightPro (red) blockers are more suitable. These block a greater spectrum of blue and green light, aiding in natural melatonin production and improving sleep quality.

• For the most comprehensive benefits, consider having both yellow and red lenses in your arsenal.

Use the yellow lenses during your screen-heavy activities and switch to the red lenses in the evening or before bedtime to help prepare your body for rest.
