Why Should IT Workers Use Blue light Glasses?

While blue light is good for the environment, blue light can affect your sleep and can cause infections Until the advent of artificial light, the sun was a great source of light, and people spent their nights in darkness. Now, we are spending our most of time in front of digital screens such as mobile phones, computers, and laptops. IT workers are top of this list. Their all work is related to digital devices. In Pakistan, there is hype about freelancing. Everyone is searching on the internet for their next stream of income. As they are spending their most of time on digital screens, they must use blue light glasses.

In our body, we have a biological clock. At night when blue light falls on our body, it changes its circadian rhythm (24 hours clock). Sleep suffers and in worse cases, it may contribute to the causation of cancer, diabetes, heart disease and obesity.

What is Blue Light?

Blue light is part of the visible light spectrum. The human eye can see this light. Blue light has the shortest wavelength and the highest energy. Not all the colours of light have the same effects. Sunlight is the most significant source of blue light and others are smartphones, tablets, and laptops. Blue wavelengths—which are beneficial during daylight hours because they boost attention, reaction times, and awareness mood. But it seems like a very disturbing night. And the proliferation of electronics with screens increases our exposure to blue wavelengths, especially after sunset.

Blue Light and Sleep

Everyone has a different circadian rhythm, but the average length is 24 hours. The circadian rhythm of people sleeping until late at night is slightly longer, while the rhythm of the earlier birds is less than 24 hours. The circadian rhythm helps us:

When to sleep and wake and also contribute to motivation. In the daytime, our motivation will be high as compared tonight.

Dr Charles Czeisler of Harvard Medical School showed, in 1981, that daylight keeps a person’s internal clock aligned with the environment.

Effects of Blue light on Sleep

While light of any kind can block the melatonin hormone, blue night light makes it more intense. Melatonin is a hormone mainly released by the pineal gland at night and has long been associated with sleep-wake cycle regulation. Harvard researchers and their colleagues conducted a study comparing 6.5 hours of exposure to blue light and exposure to green light. The blue light suppressed melatonin approximately twice as compared to other light.

Another research at the University of Toronto contributes the same results that blue light is a strong suppression of melatonin. Suppression of melatonin means no sleep at all. It also suggests that shift workers and night owls can protect themselves if they wear sunglasses that block blue light. Inexpensive sunglasses with orange lenses block the blue light, but they also block other colours, so they are not suitable for home use at night. Glasses that block only blue light can cost up to $ 100.

What do Blue light glasses do?

Bright blue glasses, also known as computer glasses or screen mirrors, are becoming increasingly popular in the digital age. After all, we spend many hours working or relaxing in front of our digital devices.

Key features of blue light glasses are:

  • Better sleep cycle
  • Reduce glare & eye strain
  • Better focus
  • Reduces CVS
  • Improve posture and wellbeing

Do I need blue light glasses?

Are you feeling tired and having trouble focusing?

If you spend a lot of time using digital devices and notice eye strain or feeling tired, blue light glasses may be helpful. According to the Vision Council, 80% of American adults use digital devices for more than two hours a day. About 70% use two or more devices at the same time. And 59% experience digital eye colour symptoms. If you are having the same eye problems, Blue light glasses can help to protect yourself.

Here are common signs that might help you to invest in some glasses: 

  • Headache & Migraine
  • Blurry vision
  • Eye Strain & Dry eyes
  • Squinting
  • Distorted Vision
  • Halos around images
  • The need to get closer to read

How to reduce the negative effects of Blue light?

  • If you work a night shift or use a lot of electronic devices at night, consider wearing blue-blocking glasses
  • Use dim red lights for night lights. The red light is unlikely to change the circadian rhythm and suppress melatonin.
  • Follow the 15-15-15 rule to protect your eyes. Take a 15-second break to view something 15 feet away every 15 minutes.
  • Use control lighting on your digital devices.
  • Expose yourself to lots of bright light during the day, which will boost your ability to sleep at night.
  • Avoid using digital devices at least three hours before going to bed.
