In today’s fast-paced world, achieving career success often hinges on factors such as high productivity, innovative thinking, and effective interpersonal relationships. Surprisingly, the key to excelling in these aspects lies within our brain, the central command center of our body. The performance of our brain, whether strong or weak, can significantly influence our career trajectory. One important aspect of brain performance is its indirect vulnerability to artificial blue light, a type of light emitted by electronic devices like smartphones, tablets, and computers. Extended exposure to artificial blue light can disrupt our body’s internal clock, known as the circadian rhythm, which regulates sleep-wake cycles, hormone release, and various bodily functions. This disruption can lead to cognitive impairments, affecting memory, attention, and mood. So, theoretically, blocking artificial blue light from our eyes should improve our health, including brain health.
Brain performance studies have put this theory to the test. In a large-scale workplace study1 performed on office workers and waste disposal drivers, there was strong supporting evidence that showed significant improvements in cognition and focus for both groups who wore a specific type of blue light-blocking glasses. In another clinical study2, the same lens technology was shown to increase melatonin–our master sleep hormone–production by 96% while increasing daytime focus and alertness by 47%. Additionally, subjects fell asleep faster and woke up less during the night. It’s important to note that not all blue light-blocking glasses are created equal. Many on the market offer minimal protection from harmful ultraviolet light, blocking as little as 5% of the harmful rays. Some may have dark coatings that distort vision and wear off over time, leaving even less protection. However, if you have the right lenses–such as the REZME® lens technology used in Gamer Advantage eyewear–in a proper pair of blue light-blocking glasses, you should not only have more long-term benefits, such as a gradual improvement in sleep and brain health, but you should also see some faster improvements, such as an improvement in eye fatigue and comfort,3 and a marked decrease in migraines and general headaches.4
These specialized glasses are designed to target the specific wavelength of artificial light, particularly the blue-violet light within the 415nm to 455nm range on the color spectrum. This range is crucial to address as it is emitted by common sources like computers and bluish-hued energy-efficient light bulbs. Effective lens technology should focus on blocking the 455nm wavelength to provide optimal protection. The link between exposure to artificial blue light and job performance is undeniable. Chronic exposure to this light can drastically reduce sleep quality by suppressing melatonin production, the hormone responsible for sleep regulation. This leads to difficulty falling asleep, disrupted sleep patterns, and decreased overall sleep quality.
Quality sleep is essential for optimal brain function. During sleep, our brains consolidate information and memories, enhancing our cognitive abilities. Poor sleep quality disrupts this process, resulting in impaired memory, reduced attention span, and diminished problem-solving skills. These cognitive impairments can have a detrimental impact on job performance, affecting our ability to remember details, focus on tasks, and solve problems effectively. Furthermore, the consequences of poor sleep extend beyond individual performance and can impact team dynamics. Chronic sleep deprivation or irregular sleep patterns can lead to irritability, impatience, and difficulties in managing stress. These factors can hinder effective teamwork, damage professional relationships, and create an unhealthy work environment.
In conclusion, prioritizing brain health is a wise move in the pursuit of career success. Minimizing exposure to artificial blue light, especially in the hours leading up to bedtime, can help maintain sleep quality and, subsequently, enhance brain function. Simple adjustments in our daily habits, such as using advanced blue light-blocking glasses and limiting screen time before bed, can significantly improve cognitive abilities. By safeguarding and nurturing our brains, we pave the way for improved job performance and healthier working relationships. So, the next time you find yourself reaching for your phone or laptop late at night, remember the crucial role your brain plays in your career success. Protect and nurture it, and watch as the benefits unfold in your professional life. Your brain is your most valuable asset on the path to achieving your career goals.
