Screens are a dominant part of life these days. Whether it’s a computer screen, tablet, or smartphone, the average American spends close to seven hours a day looking at a screen. All that screen time can put a real strain on our eyes. These screens are illuminated using light-emitting diode (LED) technology, which emits a high level of blue light, one of the light waves that could be harmful to absorb in high quantities.
Blue light waves are short and have high energy, only slightly less than the harmful UV rays that we block with sunglasses to protect our eyes. Recent research has shown that short-wave light with wavelengths between 415 and 455 nanometers may be linked to eye damage. Blue light vibrates around 380 to 500 nanometers, putting it in that damaging range. Due to the amount of time and close range at which people use blue light screens, experts are expressing concern about blue light and eye health.
Yet, avoiding screens altogether isn’t an option for many. Although we can limit leisure time viewing, many people use screens for their work and are unable to avoid using them. This is where the benefits of wearing blue light glasses come in.
Blue Light Lenses Benefits: Why is Blue Light Bad for Our Eyes and Overall Health?
One of the main benefits of wearing blue light glasses is the increased protection from potentially harmful blue light. Blue light exposure has been linked to multiple eye issues ranging from dry eyes to macular degeneration. It’s also a potential cause of sleep issues due to its effects on circadian rhythm and melatonin production. While we’ve known for years that prolonged exposure to UV rays from the sun is damaging for our eyes, increasing the risk of eye disease, there is research being conducted to see if the same is true for blue light.
Those who experience chronically dry eyes or irritation can experience the benefits of blue light glasses. Some experts say more than half of computer users experience what is called “digital eye strain,” which results in blurry vision, eye irritation, and dry eyes. A root cause is that, according to research, when you look at a blue light-emitting screen, you blink less, straining your eyes and causing them to dry out.
Blue light may also cause retinal damage, known as phototoxicity. Since blue light wavelengths are so short, they pass through your eye to the back of your retina. Frequent long exposure time may lead to an increase in the risk of the retinal disease macular degeneration. A benefit of wearing blue light glasses is you can potentially decrease this risk if you need to spend a lot of time in front of blue light-emitting screens.
Sleep issues may also be linked to blue light, so a benefit of blue light glasses is you can improve your sleep. Research shows that exposure to any light at night time can have an adverse effect on melatonin production and circadian rhythms. Poor sleep due to light exposure can contribute to the causes of chronic issues like obesity, cancer, and heart disease, according to research from Harvard. One study found that interrupted sleep cycles resulted in an increased risk of “hormone-related cancers” and suppressed leptin, a chemical that signals fullness after meals
Blue light exposure at night time is especially problematic because it essentially tells our brains that it’s daytime and halts melatonin production. So, if you’re catching up on emails or checking social media at night, you can be damaging your sleep. Using blue light lenses benefits you in many ways at night as it protects both your eyes and your sleep.
Take Advantage of the Benefits of Wearing Blue Light Glasses
Suffice it to say the benefits of blue light glasses are immense, saving your eyes from strain and your body from insufficient sleep. Those who spend hours working in front of a screen, especially during the evenings, can reap these benefits of blue light lenses.
