WHY BLULIGHT SHIELDTM GLASSES?
We live totally surrounded by screens, spending almost nine hours a day, on average, in front of digital devices. All these devices emit blue light, and since our eyes aren't protected against this overexposure, the light can be detrimental. Potential side effects are:
EYE STRAIN & DRY EYES
NECK PAIN & VERTIGO
HEADACHES & MIGRAINES
FATIGUE &
POOR WELLBEING
BLURRED & DOUBLE VISION
WHAT'S BLUE LIGHT?
Visible light, is the portion of the electromagnetic spectrum that can be perceived by the human eye. In the natural law of Physics, light propagates through space as waves and these waves carry energy. And because the energy of a wave is inversely proportional to its wavelength, the shorter the wavelength; the higher the wave energy.
Blue Light is a type of High Energy Visible (HEV) light, defined as having very short wavelength between 400 and 450 nm.
BLUE LIGHT IN THE SPECTRUM.
Every wavelength is represented by a different colour, and is classified into the following categories: gamma rays, x-rays, ultraviolet (UV) rays, visible light, infrared light, and radio waves. Together these wavelengths make up the electromagnetic spectrum. However the human eye is sensitive to only a part of this spectrum: visible light. Visible light is that part of the electromagnetic spectrum that is seen as colours: violet, indigo, blue, green, yellow, orange and red. Blue Light has a very short wavelength, and so carries a high amount of energy. Studies suggest that, over time, prolonged exposure to the Blue end of the light spectrum may cause negative impacts on eye health.
Length of the waves is measured in nanometers (nm), with 1 nanometer equaling to 1 billionth of a meter.
WHERE IS BLUE LIGHT FOUND?
Blue Light is actually found everywhere. Sunlight reaches the Earth's atmosphere and and is scattered in all directions by gases and particles in the air. Blue Light is scattered more than the other colors because the high energy ray travels as shorter and smaller waves. This is what makes the sky look blue. Naturally, your body uses Blue Light from the sun to regulate your sleep and wake cycles. This is known as Circadian Rhythm. During the day, Blue Light helps boost alertness, heighten reaction times, elevate moods, and increase the feeling of well being. Artificial sources of Blue Light include electronic devices such as tablets, smart phones and laptop computers, as well as energy-efficient fluorescent bulbs and LED lights.
SHOULD WE BE CONCERNED ABOUT BLUE LIGHT EXPOSURE?
Absolutely. Blue Light waves are classified as High Energy Visible (HEV) light. These light waves are among the shortest, highest energy wavelengths in the visible light spectrum. And because they are shorter, these "Blue" wavelengths flicker more easily than longer, weaker wavelengths. This flickering casts a glare that can reduce visual contrast, affecting sharpness and clarity.
This flickering and glaring may be one of the reasons for eye strain, headaches, physical and mental fatigue caused by hours sitting in front of digital screen of electronic device.
Our eyes' natural filters do not provide sufficient protection against Blue Light rays from the sun, let alone the Blue Light emitting from these devices or from Blue Light emitted from fluorescent-light tubes. Prolonged exposure to Blue Light may cause eye strain. Symptoms include: Sore, tired, burning or itching eyes, watery or dry eyes, blurred or double vision, headache, sore neck, shoulders or back, increased sensitivity to light and difficulty concentrating.
WHERE IS THE OVER-EXPOSURE OF BLUE LIGHT COMING FROM?
Over the years, technology has revolutionized our world and daily lives. Digital screen technology has evolved and advanced dramatically. Many of today's electronic devices use LED backlights to enhance screen brightness and clarity. These LEDs emit high energy Blue Light waves. Smart phones, computers, tablets and flat-screen televisions are just among a few of the devices that use this technology. Because of their wide-spread use and increasing popularity, we are gradually being exposed to more and more sources of Blue Light and for much longer periods of time.
WHAT ARE EFFECTS OF BLUE LIGHT ON OUR HEALTH?
Blue Light can help boost your alertness, cognitive function, reaction time, and elevates mood, which are very beneficial during daylight, but chronic over exposure to Blue Light at night can lower the secretion of Melatonin, a hormone that regulates sleep, and disrupt your Circadian Rhythm. While light of any kind can suppress the secretion of Melatonin, Blue Light at night does so more powerfully. This can throw the body's biological clock, the Circadian Rhythm, out of balance. As a result, sleep suffers, and researchers have linked short sleep to increased risk for depression, as well as diabetes and cardiovascular problems.
NEARLY 3/4 OF TEENS AGED 12-17 ACCESS THE INTERNET ON CELL PHONES, TABLETS AND OTHER MOBILE DEVICES.
Two American surveys of children aged 12 to 15 years released in July 2014, researchers at the U.S. Centers for Disease Control and Prevention found that nearly three-quarters spent at least two hours a day watching TV and using a computer.
The surveys also found that 15 percent of teens watch four or more hours of TV daily, while nearly 12 percent report using their computers for four or more hours a day. The surveys didn't ask teens about their use of smartphones.
Dr. Marjorie Hogan, a pediatrician who helped write the American Academy of Pediatrics guidelines on kids' screen time, recognizes parents have a tough task limiting TV and computers for kids in that 12 to 15 age range - especially in the age of social media.
BLUE LIGHT & DIGITAL EYE STRAIN.
Many of us stare at digital screens all day, whether it's the computer at work, our personal cell phone, playing a video game, or just relaxing and watching TV. However, this modern behavior comes with consequences. Screens are slowly changing our bodies and possibly even our minds. Digital eye strain is a new term used to describe the conditions arising from the use of today's popular electronic devicess.
NO. 1 COMPUTER-RELATED COMPLAINT:
DIGITAL EYE STRAIN.
Digital eye strain is a condition with serious symptoms that can disrupt learning and work productivity. Symptoms of digital eye strain, also referred to as computer vision syndrome, include blurry vision, difficulty focusing, dry and irritated eyes, headaches, neck and back pain. Digital eye strain has overtaken carpal-tunnel syndrome (i.e. pain, numbness, and tingling in the hand and arm) as the number one computer-related complaint.
CHILDREN ARE AT RISK.
Our children are also at risk for digital eye strain due to the increasing use of electronic devices. Children today have more digital tools at their disposal than any other time. Tablets, smart phones, e-readers, laptops, videogames to name a few.
According to a study by the Kaiser family Foundation, children and teenagers (ages 8-18) spend 7.5 hours daily engaging with digital media. Before the age of 10, children's eyes are not fully developed. The crystalline lens and cornea are still largely transparent and overexposed to light, so too much exposure to Blue Light is not advised. Parents should supervise the amount of screen time their children are permitted.
BLUE LIGHT & AGE-RELATED MACULAR DEGENERATION (AMD).
There's increasing medical evidence that Blue Light exposure may cause permanent eye damage; contributing to the deterioration of delicate cells in the center of the retina; and a part to play in causing age-related macular degeneration, which can lead to the loss of vision.
According to American Macular Degeneration Foundation (AMDF), researchers have identified Melanin as the substance in the skin, hair, and eyes that absorbs harmful UV and Blue Light rays. It's the body's natural sunscreen protection. Higher amounts of melanin afford greater protection, but as we age we lose melanin. By age 65, approximately half of the protection is gone making us more susceptible to eye disease such as macular degeneration.
EYE RETINA CAN BE HARMED BY HEV.
The retina is a thin light-sensitive membrane that lines the inner surface of the back of the eyeball. This delicate tissue can be harmed by High Energy Visible (HEV) radiation of blue/violet light that penetrates the macular pigment found in the eye. A low density of macular pigment may represent a risk factor for age-related macular degeneration (AMD) by permitting greater Blue Light damage.
A Harvard medical study states that "High Energy Visible (HEV) Blue Light has been identified for years as the most dangerous light for the retina. After chronic exposure, one can expect to see long range growth in the number of macular degenerations, glaucomas, and retinal degenerative diseases". And a paper published by the American Macular Degeneration Foundation (AMDF) reports that "the blue rays of the spectrum seem to accelerate age-related macular degeneration (AMD) more than any other rays in the spectrum".
WHO NEEDS PROTECTION FROM BLUE LIGHT OVER EXPOSURE?
The short answer to this question is: All of us do.
Everyone needs to take precautions against the potentially ill-effects of over exposure of Blue Light. Whether we work in an enclosed office or play out in the open; spend hours staring at a computer screen or texting on our cell phones, we are all being exposed to Blue Light everyday.
PROTECT YOURSELF FROM OVER EXPOSURE OF BLUE LIGHT.
1. The simplest way to help prevent overexposure to digital Blue Light is by managing the time spent using them. Take regular breaks away from the screen. One easy method is to employ the 20-20-20 rule. Every 20 minutes, take a break from your computer to look at something 20 feet away for a minimum of 20 seconds. This technique can help you avoid eye strain, and serves as a regular reminder to be conscious of excessive Blue Light exposure.
2. Avoid looking at bright screens beginning two to three hours before bed.
3. If you work a night shift or use a lot of electronic devices at night, consider wearing Blue Light blocking glasses to block potentially harmful Blue Light and minimize digital eye strain.
