Modern society is addicted to rapidly advancing technologies. After all, tech changed the way we live, work, study, play, and communicate. A typical worker will face a computer monitor all day while attending meetings, generating reports, and replying to emails. During their breaks and after their shifts, they will spend hours on their smartphones chatting with friends, using apps, checking social media, reading the news, and more. There is no doubt that these digital devices can improve efficiency and convenience, but they also come with hidden hazards. These backlit screens emit blue light that can gradually damage our eyes. Blue Optical helps to minimize this problem.

 

The Visible Light Spectrum

Visible light comes in a wide range of frequencies with each band corresponding to a certain color. They have their own unique properties such as wavelength and energy level. Rainbows are the perfect illustration with observers seeing red, orange, yellow, green, blue, indigo, and violet. When these are combined, as by spinning a color wheel, the result is pure white. It just so happens that the light emitted by fluorescent lamps and LEDs are heavy on blue light. This has a shorter wavelength, but higher energy compared to other colors. Frequent exposure can adversely affect health.

 

Digital Eyestrain

It is common for people who work with digital devices to experience eyestrain after long hours. The eyes dry out and may become painful. Irritation and blurred vision may also be observed. Taking frequent breaks can prevent eyestrain. Every 30 minutes to an hour, workers should close their eyes and relax for a few minutes. They may get up, stretch, and look out the window to somewhere far away. Looking at greenery such as trees or gardens may help. For people who get too engrossed in their work, setting periodic reminders is a good strategy.

 

Poor Sleep

Blue light can be a good thing when exposure happens during the day. It can make people perk up and help them stay awake throughout their shift. On the other hand, this can keep them awake at night when they should be winding down and getting ready for bed. This disrupts the body’s natural rhythm and makes it difficult to fall asleep. It takes a while after fiddling with a laptop or a phone before sleepiness sets in. People wake up tired in the morning, preventing them from working as well as they should. Make it a habit to put down digital devices an hour or two before nap time.

 

Macular Degeneration

Blue light may slowly damage the retina and cause visual impairment in the form of macular degeneration. People will not feel this right away. It will take years of constant exposure to see the effects and those who are older are more likely to develop this condition. A study showed that blue light had the ability to trigger the release of toxic substances from photoreceptor cells. This could lead to age-related macular degeneration. Many are interested in ways to prevent AMD in their old age given that they cannot work without their digital devices.

One of the best solutions is filtration. It is possible to block much of the blue light coming from the screens to lower exposure and mitigate effects. This can work in two ways. First, a transparent screen that can filter blue light after installation on the devices themselves. Second, people can wear glasses with a special blue light filter coat. Both allow people to work without any worries of eyestrain, poor sleep, and AMD. Of course, it would still be a good idea to take periodic rests and put the phone down at night.
