Knowing the effect of the blue light on human eyes, from the perspective of physics and optometry; we aim to reduce the dangers of blue light exposure among computer and smart phone users in Nigeria and Africa at large. Through our researches, we discovered that this generation best referred to as the screen age may suffer serious eye problems and other health challenges, if proper awareness about the blue light blocker is not made. Anti-blue light glass or best called computer glass is the surest way to avoid the hazard emanating from the daily exposure to the dangerous rays called blue light.

 Blue light has a wavelength of between approximately 380nm and 500nm; making it one of the shortest, highest-energy wavelengths. This particular wavelength of light has been shown to potentially damage ones ’retina, which could lead to vision impairment. Researches have shown that approximately 6 in 10 adults experience symptoms of digital eye strain after using devices for more than 2 hours. Common symptoms of such digital eyestrain include: headaches, blurry vision, migraine and sleep distortion; kids and teens experience same.

 Knowing that almost 90% of the young people of this generation make use of smartphone or computer it became a necessity to ensure that anti blue light glasses are made available and affordable to the teaming population of Nigerians. Blue-light filtering glasses can reduce the potential damage to your eye and could improve symptoms of computer vision syndrome (another name for digital eye strain). It is important to note that even if you don’t need a prescription offered by an eye specialist, you should consider a pair of glasses with blue light blocking technology. Our company C-Field link partners with an American registered company ZAKLINA, to ensure that we serve humanity by making the glasses available and affordable to them, least we have a nation of blind people.

Below are a few benefits to wearing blue-light glasses:

  • Benefit 1: Relieve eye discomfort

Excess device usage can lead to computer vision syndrome or digital eye strain. Glasses with blue light filtering technology can enhance your focus and reduce eye strain, resulting in making your eyes feel less tired and improving productivity. Another way to reduce eye strain is to make sure you take regular breaks from the screen.

  • Benefit 2: Improve sleep

One of the more surprising impacts of exposure to screens is the potential to negatively affect sleep patterns. Blue light has a high energy frequency that can increase alertness and delay the body’s release of melatonin, which helps induce sleep. In general, we should all avoid using blue-light devices one to two hours before sleep. Blue-light blocking glasses can reduce the impact of blue light, enabling you to use your devices before bed and still get a good night’s sleep. However, the best option is to put the screen down before it’s time for bed.

  • Benefit 3: Reduce the likelihood of Age-Related Macular Degeneration (AMD)

AMD is a leading cause of blindness. Blue-light blocking lenses can help avoid or delay this condition by preventing blue light from impacting your eyes. 


With protective technologies, blue-light blocking glasses can reduce the impact of blue light and digital eye strain. They can help alleviate the discomfort from too much time on devices, improve sleep and reduce the likelihood of AMD.
