WHAT IS BLUE LIGHT?

Blue light is everywhere. It is a segment of the visible light spectrum responsible for keeping you alert, however research has found that excessive exposure to it is not healthy for our eyes. Blue light is found naturally in sunlight, but also emitted in high concentrations from our digital devices - phones, tablets, laptops, etc.

Natural Blue Light

Blue light from the sun is a form of natural blue light, it is essential for regulating your sleep and wake cycles, and your body clock. Blue light has also been found to improve alertness, reaction times, and create a sense of wellness. Blue light from the sun is also accompanied by all the other colours from the light spectrum, making it a balanced and healthy light source.

Artificial Blue Light

Blue light can also be found artificially from electronic devices which include your smartphones, tablets, computer screens, TV screens, and all light emitting devices that we face every day.

PROBLEM WITH TOO MUCH BLUE LIGHT

The shorter the wavelength of light, the higher the amount of energy it contains. Blue lights are found at the very beginning of the visible light spectrum, this means it contains intense amounts of energy ranging from 400 nm to 495 nm.

The light found in digital devices and light bulbs contain far more blue compared to other colours in the spectrum, meaning that our eyes are subjected to an excessive amount of imbalanced blue light. This blue light penetrates the eye, and over the course of a day it will cause digital eye strain.

WHAT IS DIGITAL EYE STRAIN?

Digital Eye Strain (also known as Computer Vision Syndrome) is characterized by dry itchy eyes, headaches, and fatigue. Over time, digital eye strain can potentially progress into macular degeneration. During winter time, the sun does not come out as much as it would in the summer, hence, we tend to rely on artificial light sources that have high concentrations of blue light. Prolonged exposure to high concentrations of blue light in the absence of sunlight contributes to stress, anxiety, and depression (SAD), because it keeps our cortisol levels (stress hormone) chronically high.

RESEARCH

According to The Vision Council, an independent group of eye doctors comprised of optometrists and ophthalmologists, the average American spends more than 7 hours in front of a screen every day. Much of this computer use happens at work (or when we’re on our phone). According to the same group, nearly 50% of all Americans have jobs that require prolonged computer use.

With this increased screen time comes consequences. The American Optometric Association estimates that 50% - 90% of computer users suffer symptoms of Digital Eyestrain. The Vision Council reports that 57% of Baby Boomers report symptoms of Digital Eye Strain; alarmingly, that number jumps to 63% for Gen Y and up to 70% for Millennials. That’s a 7% increase per generation! This comes as no surprise given that The Vision Council claims people can suffer from Digital Eye Strain with as little as two hours a day in front of a screen.

BLUE LIGHT GLASSES

Q+ Glasses has been specifically developed for people who spend a lot of time indoors and are exposed to the blue-violet and LED light of digital devices like smartphones, TVs, and tablets without large distortion to the colour you do want to see.

The high quality lenses has been specifically designed to block out ALL UV light (200 – 400 nm) which is most harmful but invisible light that you do not see, and 35% of Blue light (400 – 495nm).

Recommended by doctors from around the world, human should minimize our eyes form long exposure to high energy light such as blue light and UV light.
