Ever felt dry eyes, irritability, and a pounding headache after prolonged use of screen?
Do you feel any problem in falling asleep?
Is your sleep not peaceful?
If you think this is because of work-related stress, your family problems or because of what your life is throwing at you? Well, this can be right, but another contributing factor you might want to explore is overexposure of blue light.
What is Blue Light?
Blue light is short yet high energy, blue wavelengths of the light spectrum. The light-emitting from the digital devices is predominately blue light. Blue light poses several disadvantages including insomnia, fatigue, dry eyes, headaches, and blurred eye vision.
People with prolonged blue light exposure should use blue light glasses. Blue Light Glasses block a significant amount of blue light regardless of the source of light.
What Are Blue Light Glasses?
To combat the hazards of blue light, the blue light glasses have evolved. We also know blue light glasses as blue light filter glasses, anti-blue light glasses, and Bluray optical computer glasses.
Benefits Of Blue Light Glasses
Blue light glasses have filters in the lenses that either block or absorb the blue wavelength as well as ultraviolet lights in some cases. Using blue light glasses especially after the sunset is highly recommended for people with over two hours of screen exposure at a time.
Let us discuss some benefits of the blue light glasses in detail.
Ease digital eye strain
According to the survey, an average American spends about half of the waking hours looking at a screen. This screen exposure is responsible for the growing complaints of irritability, mood swings, and tiredness. A contributing reason for this is the exposure to the blue light. The blue light causes digital eye strain. Major symptoms of eyestrain include sore or irritated eyes, dry eyes, and difficulty in focusing.
Now, how can you prevent eye strain? Avoiding digital screens is definitely not an option. Therefore, you must use a computer eyewear while facing digital screens. Computer eyewear includes Bluray optical computer glasses and computer screen glasses, also known as anti-blue light glasses.
There is a consensus on the fact that blue light emitted from digital screens can disturb the sleep cycle as well as the quality of sleep. The blue light from the digital devices inhibits the production of melatonin, a chemical responsible for inducing sleep.
The human body has an internal clock system that times the working of internal functions. This 24-hour cycle is called the circadian rhythm. This human clock system also takes cues from the external environment. Like darkness and activity level outside. During the daylight, the blue component of sunlight keeps the body alert, and moods settled. However, after the sunset, the blue lights mostly coming from screens give wrong signals to your body clock. It tells it to keep awake and alert while the body physically needs rest. These mixed signals can play havoc with your mental and physical health and wellbeing.
An experiment conducted at Harvard studied the effects of blue light exposure for 6.5 hours. They compared it to the exposure of green light for the same time and with the same brightness. According to the results, the blue light suppressed the production of melatonin for twice as long 0as the green light. It also shifted the circadian rhythms by three hours as compared to a shift of 1.5 hours by green light.
From this data, we can conclude that for a healthier lifestyle and better sleep pattern, anti-blue light glasses are a must. Blue light filter glasses also called blue light glasses or anti-blue light glasses, have the quality to filter the blue component from the light. Using blue light glasses while facing the screens helps you to regulate the production of melatonin and to enjoy ample peaceful sleep. As a result, blue light filter glasses help to reduce fatigue and promote better productivity.
The retina is the light-sensing nerve tissue of the eye that records the images we see. It sends the images to the brain via the optic nerve. The macula is the central portion of the retina that gives us a clear vision and the ability to see the fine details.
Overexposure to blue light can bring irreversible damage to the Macula. Macular Degeneration, also called age-related macular degeneration (AMD or ARMD), is an optical condition. In this disease, the macula in the eye deteriorates gradually leading to partial blindness over a period of time. The deterioration of macula is a progressive process. It starts with some blind or dysfunctional spots in the center of the eye. As the condition worsens, the light-sensitive cells in the macula get weaker and may die causing central vision loss. This is an irreversible eye disease.
Anti-blue light glasses help us protect the Macula from the damage caused by lights. They remove the blue light component and decrease the chances of damage contributed by high-intensity exposure.
Anti-blue light glasses play a very important role to combat with Macular Degeneration. This is important because macular degeneration poses the risk of irreversible eye damage and partial blindness. According to the research, using a filter that blocks a major part of the blue component helps to protect the function and morphology of macula. Using blue light eyewear like anti-blue light glasses or blue light filter glasses is one way to protect your eye function.
Choosing The Right Anti Blue Light Glasses
Blue light eyewear or computer eyewear does not have to be ugly orange glasses. Technology has evolved over the past years and now you can find smart fashionable anti-blue light glasses in the market.
The right blue light glasses;
- Don't darken your vision
- Filter out 90-100% blue light
- Block ultraviolet lights too
So, a pair of good quality blue light glasses are a very important accessory in today’s life. Since we can not eliminate the blue light from our life, the only choice it leaves us with is using computer screen glasses or anti-blue light glasses.
