Have you ever found yourself left with a pounding headache after spending hours staring at your computer screen? Or maybe you can’t fall asleep after watching TV with your friends on the couch.
So what’s the deal?
Well, it turns out that the blue light given off by screens such as computer and television screens can cause a whole slew of other health issues. Luckily, we have a solution for you! Asia’s secret fruit, Gac, provides your body with nutrients(1) that help fight blue light and other health issues(2) and keep your eyes healthy.
Okay, so we’ve identified that blue light is the one cause for migraines and insomnia, but what actually is blue light? Let’s break it down.
Sunlight actually contains several different colored light rays - red, orange, yellow, green, and blue - that come in various shades according to the electromagnetic radiation contained in each ray.
When all these light rays are combined they create the typical white light, or sunlight, that we’re used to.
However, when we break white light apart and look at the properties of each type of light ray, we see that the different types of light have different wavelengths and different levels of energy.
Light rays with long wavelengths, such as red light, contain less energy while light rays with shorter wavelengths have more energy. Blue light is the shortest wavelength of visible light, which means that it has the highest level of energy.
Wavelengths are measured in nanometers (nm); the visible light spectrum’s electromagnetic radiation is made up of wavelengths of about 380 nm on the blue end.
Typically blue light is visible light ranging from 380 to 500nm, although it can be broken down into blue-turquoise light (380nm to 450nm) and blue-violet light (450nm to 500nm).
The front portion of the human eye (the lens and the cornea) is very good at blocking harmful UV light from reaching the back of the eye (the retina). However, blue light is able to easily pass through the anterior part of the eye and reach the retina, which can cause eye strain and even lead to long-term damage.
One reason that blue light has become such an important health topic is because high energy blue light is not focused and scatters easily. Computer screens and digital devices emit large quantities of blue light and creates visual “noise” in your environment.
This “noise” is known as digital eye strain, where contrast is reduced and the eye needs to work harder to look at the objects in the environment.
Incorporating carotenoids(3) into your diet can help your eyes fight this noise and function efficiently.
So far everything we’ve discussed makes blue light(4) seem pretty harmless. While generally there’s nothing wrong with blue light, it can actually have some negative side effects for humans. A few issues that blue light can cause include:
Some of these seem pretty scary. Let’s take a closer look at how blue light is linked to these issues.
Remember how we mentioned that blue light passes through the cornea and the lens to reach the retina at the back of the eye?
Well, when too much blue light passes through to the retina it can damage the cells there and can lead to permanent vision loss. While there is no scientific number for what constitutes an excess of blue light, it’s important to keep in mind that man-made blue light from digital devices could lead to eye concerns over time.
Lutein and Zeanthin is a type of antioxidant that can help prevent your eyes from macular degeneration and can decrease the risk of developing macular degeneration from blue light.
Digital eye strain, also known as computer vision syndrome, is the discomfort associated with spending too much time staring at a screen.
This can occur from working long hours at a computer, using a smartphone or mobile device excessively, or from watching television for extended periods of time. An excessive amount of time is considered a period of two or more consecutive hours.
Some of the signs that you’re suffering from digital eye strain include:
Keep an eye out for these types of symptoms to stay healthy(8) and avoid computer vision syndrome!
Getting enough sleep can be difficult, especially when coupled with blue light excess. Daylight exposure keeps a person’s internal clock aligned with the environment and helps your body know when it’s time to go to sleep.
Exposure to light suppresses the secretion of melatonin, which is a hormone that helps signal your body it’s time to go to sleep. When your body isn’t producing as much melatonin, you may have difficulty falling asleep and find yourself lying awake at night.
Keeping a healthy diet(9) helps you to get better sleep and keep your body functioning at its prime. One food you can incorporate is gac, which has been shown to have many antioxidants and properties that fight the effects of blue light.
While there are several health concerns that are caused by blue light, the good news is that there are plenty of ways to conquer the health issues brought about by it.
The simplest way to reduce the effects of blue light damage is to limit screen time to under two hours. This can help you avoid the headaches and negative effects associated with being exposed to blue light for too long.
Another way, and our favorite way here at gaclife.com is to incorporate gac into your diet. Gac has a high concentration of carotenoids(10) as part of its chemical makeup(11), which helps improve eye sight and night vision.
The most important carotenoids for improved vision are lycopene(12), beta-carotene(13), lutein(14), zeaxanthin(15), and Vitamin A(16), all of which are found in gac fruit. In fact, gac contains 410 micrograms of beta-carotene and 3.72 mg per gram of lycopene(17).
That might not sound like a lot, but in terms of your daily value, gac can provide your body with the vitamins and antioxidants that it needs to not only get through the day but to help rebuild degeneration caused by blue light.
At GacLife we have a variety of gac beverages, but we recommend Drinkable Beauty for your eyesight. Take a swig and know that you’re helping your eyes beat the blue light!
