Ever walked into an office or classroom and wondered WOW the lighting is so bright in here?
Let me tell you why. If someone told you there was a direct or indirect effect on your mood and performance due to the lighting you probably wouldn’t believe me? well, listen up!
if you're one of the many that are working from home or have started due to (COVID-19) it sounds like an amazing idea until you're actually in the midst of it laptop in lap, butt on the sofa, and keeps getting distracted by your pet's cuteness how comfy your bed looks from here what snacks are in the fridge.
In this article, we are going to cover off the two different variations of light and the health benefits that can improve your overall performance and your office environment so the million-dollar question
What is blue light? The Love-Hate Relationship
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. The 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. Just like the sun we receive an artificial fabrication of the exact same light through the devices we use and the lights we use to brighten up low lit areas.
Proper lighting makes most tasks easier but chances are that the existing lighting in your home space is inadequate so...
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 healthy circadian rhythm. Too much exposure to blue light late at night (through smartphones, 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.
Blue-enriched white light
- stimulates the brain,
- improves alertness
- and will help you sleep better at night.
not only does it reduce eye strain but it will also make you feel less tired overall.
Let’s look at other examples, for instance, most vehicles are fitted with high beam lights when natural lighting is not available these are encouraged to be used in low lit areas to assist drivers to focus better and regulate alertness
University and high school classrooms and any facilities or jobs that require full cognitive awareness over long periods have all taken the same approach how do you expect to learn algebra and not fall asleep right? Its the lighting.
In Summary: a healthy substitute to natural lighting is blue-enriched white lighting in the form of LED or Ring Lights which are very inexpensive. The reason for this is that Ring Lights create evenly proportioned light distribution because the light is so evenly spread ('There's no focal point") the tone and colour can be changed from white to warmer tones and also the strength of the brightness can be controlled
if (your job requires you to work behind a computer) for long periods of time extra protection is needed please read below:
The second variation of light is the direct blue light that can be produced by the very device you're reading this from yes your phone!
- LCD Televisions
- Laptops and Computers
- Smartphones (the culprit)
Here's an example if you looked a light bulb for 3 hours straight that would be the equivalent of being on your mobile phone for an entire day or working an office job which some of us can't help.
Our eyes are in a constant battle to try and heal after the long lengths of exposure to radiation dust UVB and UVA rays blue-light and our busy lifestyles. That it's almost impossible to ensure the health of our eyes are top-notch
- Phototobia and light sensitivity
- Dizziness and can worsen symptoms of dry eye
- Vision Syndrome
- Eye Strain
Are some of the ailments that may be developed over long periods of time if not prevented or treated early
let's not get confused
There is a reason your eyes go all funny when you stare at your computer for too long. "Digital eye strain is more likely related to our prolonged exposure to smartphone and tablet screens, rather than blue light itself," explains Khan. "When we are using our devices, we forget to blink as often as we should (approximately 15 to 20 times a minute)," she says
the best alternative to ensure you have adequate lighting whilst you are working in your home office is LED Ring Light dimmable lighting equipment which is very inexpensive and can be positioned to an office desk via a tripod
if you are working on your computer for long periods of time for extra protection anti-reflective glasses or blue-blocking glasses can save your eyes from any potential on-going damage that may result in a decrease in cognitive function or overall eye health
