High-energy visible (HEV) light, or blue light, is a portion of the visible light spectrum that has a high frequency and so can be seen by humans. In general, the greater the energy of both visible and invisible light, whose wavelengths are measured in nanometers (nm), the shorter they are. Because of its shorter wavelength, blue light may generate more power than other colors. The eyes are unable to efficiently filter blue light, therefore more of it reaches the retina than with other colors of the spectrum. There are certain advantages to being exposed to blue light electronic shops, but there are also some risks to our eyes and general health.

Blue light with a lot of punch

Blue light is present in our environment almost continuously. While sunlight is the most abundant source of blue light, other sources include electronic devices such as laptops, computer displays, cellphones, tablets, televisions, and fluorescent and compact fluorescent blue light electronic shops. Because of our closeness to displays, the amount of time we spend using devices, and the cumulative effect of using devices daily, blue light exposure from digital devices is a specific reason for worry.

What Caused That Blue Light Increase?

The blue light emitted by the sun and by artificial sources like the LEDs in our electronic gadgets is different in important ways. The majority of the LEDs’ emitted light is between 400 and 490 nanometers in wavelength. The 435–440 nm range is where many LED displays excel. The medical community expresses serious worry about this range.

Should we be taking precautions?

There has been a rise in the popularity of glasses that promise to mitigate the effects of blue light emitted by electronic devices such as smartphones and tablets. Overexposure to blue light, according to the ads for these spectacles, may cause eye issues. But there is no evidence that the quantity of this light produced by computer and mobile displays is detrimental.

Taking precautions against blue light in the absence of data that it is hazardous might have unintended consequences that are much more detrimental than the light itself. Such drastic action is premature and might have unintended consequences.

Taking frequent pauses is the greatest method to prevent eye strain caused by blue light from electronics. The 20-20-20 rule can help us with this: every 20 minutes or so, look at anything at least 20 feet away for 20 seconds. When your eyes feel dry, you may also use artificial tears to moisten them. Given the paucity of proof for their efficacy, we also advise staying away from so-called “blue light” spectacles. For the most part, regular prescription glasses are OK to wear when using a computer.

Many of us indeed spend the better part of each day staring at the screen of some kind of digital electronic gadget. Think about the fact that 60% of the population spends more than 6 hours a day staring at a screen. Those that fall into this category may find that blue light filters are a practical solution to the problem of eye strain. Blue light filters for electronic devices like smartphones, tablets, and computers may be found at any retailer that sells such items. A predetermined option may even be included in the hardware itself.

Seeing the Blue Light for What It Is:

Electronically induced blue light, or blue light, is a spectrum of light that may damage the eye’s natural components. Television, computers, cellphones, tablets, and portable game consoles are just a few examples of the many electrical and digital gadgets that hold this kind of light upon which we rely throughout the day. While some blue light is necessary to maintain eye activity throughout the day and night, a significant quantity is harmful and may lead to macular degeneration.

In what ways can exposure to blue light harm your eyesight?

Did you know that your capacity for clear vision might be impaired by exposure to unfiltered blue light? As the blue light from our digital gadgets never stops and our eyes constantly concentrate and refocus, we run the risk of developing “Computer Vision Syndrome” (CVS), in which the retinal qualities deteriorate and the natural potential of sight is lost over time. Human eyes begin to respond after being exposed to this hostile stream of light because the eyes are forced to focus on a more intense continuity of the rays than they are used to.

Invest in some screen protection software right now

When it comes to preventing digital blue light from straining your eyes, no other solution compares to our Digital Screen Protection. This lens fits comfortably in any frame and works with any other lens type. Protecting your eyes from digital devices is as easy as coating your ordinary lenses with digital screen protection. This works with progressive or bifocal eyewear. Experiments with do-it-yourself passthrough devices confirm that our blue-cut lenses effectively block 17% of light. Do not be hesitant to dive headfirst into the online world. Here you may get glasses that protect digital screens.

Which direction should we look for blue light?

The presence of blue light is ubiquitous in our culture. We’ve established that digital technological gadgets house it, but that’s not all there is. There are only two main types of blue light emitters:

Sun-derived blue rays

The sky is blue because of what, exactly? Of course, the blue light is to blame. Sunlight is red in hue, however, on Earth it appears blue or very pale blue. The blue color of the sky is caused by the collision of short wavelengths of sunlight with molecules of air. The benefits of natural blue light include improved circadian rhythms (sleep and waking times), mood elevation, an overall sense of well-being, enhanced memory and cognitive performance, heightened alertness, and faster response times.

The blue light produced in a laboratory:

Devices like laptops, cellphones, and televisions also contribute to man-made blue light pollution. Artificial blue light may also be produced by fluorescent bulbs and LED lights. The usage of electronic devices, especially those that emit blue light, has been linked to sleep disturbance, eye tiredness, and headaches.
