What is Blue Light?

Sunlight is made up of red, orange, yellow, green, blue, indigo and violet light. When combined, it becomes the white light we see. Each of these has a different energy and wavelength. Rays on the red end have longer wavelengths and less energy. On the other end, blue rays have shorter wavelengths and more energy. Light that looks white can have a large blue component, which can expose the eye to a higher amount of wavelength from the blue end of the spectrum.

Where Are You Exposed to Blue Light?

The largest source of blue light is sunlight. In addition, there are many other sources:

  • Fluorescent light
  • CFL (compact fluorescent light) bulbs
  • LED light
  • Flat screen LED televisions
  • Computer monitors, smart phones, and tablet screens

Blue light exposure you receive from screens is small compared to the amount of exposure from the sun.  And yet, there is concern over the long-term effects of screen exposure because of the close proximity of the screens and the length of time spent looking at them. 


What Are The Benefits of Blue Light?

Blue light is needed for good health:

  • It boosts alertness, helps memory and cognitive function and elevates mood.
  • It regulates circadian rhythm – the body’s natural wake and sleep cycle. Exposure to blue light during daytime hours helps maintain a healthful circadian rhythm. Too much exposure to blue light late at night (through smart phones, tablets, and computers) can disturb the wake and sleep cycle, leading to problems sleeping and daytime tiredness.
  • Not enough exposure to sunlight in children could affect the growth and development of the eyes and vision. Early studies show a deficiency in blue light exposure could contribute to the recent increase in myopia/nearsightedness.

 How Does Blue Light Affect the Eyes?

Almost all visible blue light passes through the cornea and lens and reaches the retina. This light may affect vision and could prematurely age the eyes. Early research shows that too much exposure to blue light could lead to:

  • Digital eye strain: Blue light from computer screens and digital devices can decrease contrast leading to digital eyestrain. Fatigue, dry eyes, bad lighting, or how you sit in front of the computer can cause eyestrain. Symptoms of eyestrain include sore or irritated eyes and difficulty focusing.
  • Retina damage: Studies suggest that continued exposure to blue light over time could lead to damaged retinal cells. This can cause vision problems like age-related macular degeneration.



  • ANTI BLUE LIGHT FILTER - The lens in our glasses blocks up to 35% of harmful blue light, and 100% of UV 400nm. Blue light is a harmful portion of light emitted by digital devices. Studies suggest that continued exposure to blue light over time could lead to damaged retinal cells. This can cause vision problems such as macular degeneration.
  • MATERIAL/QUALITY - Our frames are made of a material called Acetate, which is a nylon-based plastic. Acetate is stronger, more durable, and more flexible than regular plastic. It is more resistant to pressure placed upon the frames and can bend further before breaking.
  • REDUCE EYE STRAIN/FATIGUE - Our Glasses help reduce eye strain, headaches, blurred vision and fatigue due to over exposure of blue lights from digital devices. HEV light from computers, phones, and tablets can causes the eyes to not only work harder but puts them at risk of aging faster.
  • SLEEP BETTER - Too much exposure to blue light late at night can disturb the wake and sleep cycle (Circadian Rhythm), leading to problems sleeping and daytime tiredness. Our glasses block the blue light that you absorb at night while using your smart phones, tablets, and computers.
