Bye Bye, Blue Light!
Written by x
In modern-day & age, digital devices have become an essential part of our daily lives (shocker? We think not). Studies reveal that 60% of us spend almost half a day on our digital devices. Curious to find out the effects this has on us? Scroll down for the 411.
What is blue light?
Blue light is the shortest wavelength of light on the visible light spectrum. The short-wavelength produces high amounts of energy scattering blue light more easily than any other visible light. In basic English – this means the shorter the wavelength, the more harmful it gets.
“43% of adults have a job that requires prolonged use of a tablet or computer”
Where does blue light come from?
The largest source of blue light is sunlight. In addition to the sun, we are exposed to blue light by:
- Fluorescent lights
- CFL (compact fluorescent light) bulbs
- LED lights
- Flat-screen LED televisions
- Computer monitors, smartphones, and tablet screens
Although the sun is the largest source. Eye care specialists are more concerned about digital blue light due to the proximity of our screens & the amount of time spent looking at them. The sun, being the short-wavelength, high energy blue light scatters more easily than other light sources which impact our eyes less than what a digital device would.
How does it affect us?
Cue the concern. Being exposed to blue light can cause serious long-term damage to your eyes. Almost all visible blue light passes through the cornea, lens & 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:
The continuous blue light exposure in the evening’s from our digital screens and fluorescent light bulbs are the same light source as the sun suppresses the secretion of melatonin.
- MUSCULAR DEGENERATION
Blue light penetrates right through to the retina (the inner lining of the back of the eye). Exposure to blue light can damage light-sensitive cells in the retina causing macular degeneration, which can lead to vision loss.
- Digital eyestrain:
Studies showed 70% of adults who regularly use electronic devices report symptoms of digital eye strain. When you’re looking at computer screens & other digital devices that emit significant amounts of blue light, this unfocused visual “noise” reduces contrast & contributes to digital eyestrain. Symptoms of eyestrain include:
- Sore or irritated eyes
- Difficulty focusing
- Dry eyes
- Blurred Vision
- Neck and shoulder pain
Bye Bye Blue Light
Research has shown that Blue light Blocking lenses increase comfort when you’re viewing digital devices for extended periods.
Here are a few things you can do to help decrease your blue light exposure:
- Invest in blue light blocking glasses. Browse our full Blue Light collection here.
- When staring at a digital screen, blink more often.
- Clean your screen, as a smudge-free, dust-free screen helps reduce glare.
- Change digital device background colours from bright white to warmer colours to reduce eye strain.
- Take regular breaks using the “20-20-20” rule: every 20 minutes, shift your eyes to look at an object at least 20 feet away for at least 20 seconds.
