Eye Protection Helper: Blue Light Blocking Glasses

With the increasing popularity of mobile phones and computers, blue light blocking eyeglasses are becoming more and more popular, and many people around them are beginning to wear them. Blue light blocking eyewear can effectively reduce the high-energy blue light generated by computers, mobile phones and other sources of light that can be damaging to the eyes, making them the best choice for modern young people. So, let's learn about blue light blocking eyeglasses!


What is Blue Light Radiation?


First of all, when we talk about blue light here, we mean high-energy short-wave blue light. According to introduction, high-energy short-wave blue light is relatively high-energy light with a wavelength between 400 nm and 450 nm.


It is important to note not all blue light is harmful. What is really harmful is short-wave blue light within 400 to 440 or 450 nm. Blue light between 450 and 500 nm has a function of regulating biological rhythm, which is related to sleep, mood, memory and so on and is actually beneficial to the human body.


Furthermore, short-wave blue light is not necessarily damaging to the human eye which is related to the irradiation intensity and irradiation time. When the illumination reaches a certain degree and lasts for more than two hours, it is possible to cause damage to the retina.


Where does Harmful Blue Light Radiation Occur in Daily Life?


Blue light can be found everywhere in daily life, but the main source of exposure to harmful blue light is LED LCD screens.


Our life is now full of LED LCD screens, such as computers, which is the main source of blue light faced by office workers, followed by mobile phones. Especially with the rise of smart phones, the object of blue light radiation also extends from office workers to children and the elderly in the family, and this phenomenon is becoming more and more serious.


How does Blue Light Radiation Harm to Your Eyes?


1)Eye Disease:


High-energy short-wave blue light has very high energy, can penetrate the lens to the retina, causing the atrophy and even death of retinal pigment epithelial cells. The death of light-sensitive cells can lead to vision loss or even complete loss, and the damage is irreversible. Blue light can also cause macular degeneration. The crystals in the human eye absorb part of the blue light and gradually become cloudy, and most of the blue light will penetrate the lens. Especially in children, the lens is clear and cannot effectively block the blue light, which is more likely to lead to maculopathy and cataracts.


2)Eye Fatigue:


Due to the short wavelength of blue light, the focus does not fall on the center of the retina, but a bit farther away from the retina. In order to see clearly, the eyeball will be in a state of tension for a long time, causing visual fatigue. Long-term visual fatigue may cause people to deepen the diopters of myopia and become unable to concentrate and other symptoms, affecting people's learning and work efficiency.



3)Bad Quality of Sleep:


Blue light inhibits the production of melatonin, an important hormone that affects sleep and is known to promote sleep. This could also explain why using a phone or tablet before bed can cause poor sleep or even difficulty falling asleep.


How do Blue Light Blocking Glasses Protect Your Eyes?


Blue light blocking glasses can effectively block harmful blue light into your eyes and greatly relieve eye fatigue and other discomfort. They play a role in reducing harmful blue light. Blue light blocking lenses can reduce the blue light by about 30%. In this way, the short-wave blue light is filtered and the beneficial blue light is retained, which is more scientific for human body.



How to Effectively Prevent Problems Caused by Blue Light?

1) Arrange the Internet time reasonably and develop good living habits


2) Reasonable adjustment of dietary structure to enhance body immunity


3) Wear blue light blocking eyeglasses or eyewear with blue block pro lenses when you use electronic products in daily life


4) When surfing the Internet and watching TV, it is advisable for you to turn down the brightness and warm the color temperature


5) Reduce the amount of time you spend online, especially by avoiding staring at your phone or computer in the dark


6) Doing more outdoor exercise can effectively strengthen eye regulation
