Do Blue Light Glasses Help Relieve Headaches, Migraines, and Other Symptoms?

Blue light glasses are well-known among migraine and headache sufferers, particularly among those who consider blue light as a trigger. However, there is a wealth of information available that may be misleading.  We'll explain what you need to know about blue light exposure, what type of glasses to look for, and why you might want to reconsider purchasing blue light glasses for your migraines in this post. 

What Should You Be Aware Of Regarding Harmful Blue Light?

The sun is the primary source of blue light in our life. However, the long-term effects of artificial sources of blue light provide the majority of concern about blue light, mainly because these light sources are frequently excessive and close to the eye. To protect yourself from it, one can buy blue light glasses online. 


Among the artificial sources of blue light are the following: 

 

  1. Luminaires fluorescents (standard in retail stores, offices, and some homes) 
  2. Compact fluorescent light bulbs (CFLs) 
  3. LED televisions with a flat-screen 
  4. LED illumination 
  5. Tablets and smartphones 
  6. Monitors for computers 

The human eye is not adaptable to blocking blue light on its own. As a result, practically all visible blue light passes past your cornea and onto your retina. Continued exposure to blue light may cause damage to the retinal cells over time, which may contribute to disorders such as age-related macular degeneration, eye cancer, and cataracts. Additionally, it is well established that exposure to blue light too close to bedtime can hurt sleep due to abnormalities in the body's melatonin production. 


According to the Vision Council, "about 80% of American people report spending more than two hours per day on digital devices, roughly 67 percent report using two or more devices concurrently, and 59% report suffering symptoms of digital eye strain." These symptoms may include the following: 


  • Parched eyes 
  • Headaches 
  • Perplexed vision 
  • Neck and shoulder discomfort 

Blue light scatters easily due to its short wavelength and vital energy, making it more difficult for your eyes to detect contrast. Computers and other digital devices create an amount of this blue light, referred to as "visual noise." Additionally, we blink less frequently when we use these devices. All of these causes contribute to eye strain, which may develop headaches and the other symptoms mentioned previously.  If you already suffer from migraines, blue light glasses can help you to get rid of the exposure that triggers you.

Migraines and headaches caused by blue light 

Blue light is visible light with a high energy level that can harm your eyes and overall health. Staring at screens can cause our eyes to work overtime, putting them under stress and strain. 


This can result in digital eye strain (DES), which can cause discomfort in the eyes, vision issues, and headaches. When primarily related to screen-time blue light problems, DES is sometimes referred to as computer vision syndrome. Because light and eye strain together are common migraine triggers, blue light can be challenging for migraine sufferers. 


Participants were exposed to several blue, white, green, red, and amber light levels in a brief study. The study discovered that blue light had the most significant detrimental effect on migraine sufferers.

Are Blue Light Glasses Effective? 


The studies published in the American Journal of Ophthalmology recently examined 120 computer users who reported experiencing symptoms associated with blue light exposure. They were assigned a two-hour computer activity and given the option of wearing blue light glasses or transparent (placebo) glasses throughout that time. Everyone was made to assume they had been given blue blockers. 


After the two-hour task, there was no change in the eye strain symptom score of participants who wore genuine blue light blocking glasses versus those who got the placebo. In brief, the blue light glasses were no more effective at relieving eye strain than standard clear lenses. Regrettably, this means that they will not alleviate headaches caused by eye strain. 


It's worth noting that this study focused exclusively on blue blockers - not on migraine blue light glasses. And, as you will soon discover, there is a significant difference between blue blockers and genuine migraine blue light glasses. 

The Distinction Between Migraine And Blue Light Glasses!


Not all blue light is the same. Neither are blue light glasses or migraine-prevention eye wear. Blue light blocking glasses are intended to filter out blue-violet light, primarily violet. According to the most recent studies, their actual effect on eye strain and other symptoms is unknown. 


Migraine sufferers must understand that the wavelengths of light most commonly associated with headaches are not violent but blue and amber. Thus, while "blue light blocking glasses'' are intended to alleviate eye strain, they are not designed to block the exact wavelengths of light known to aggravate and trigger migraine attacks.


The crux 

Blue light is a type of visible light with a high energy level emitted by the sun and artificially emitted by digital equipment. Prolonged exposure to blue light can have negative consequences, such as eye strain, neck pain, and headaches. 


Blue light headaches are frequently associated with digital eye strain, produced by spending an excessive amount of time. While it may be difficult to disconnect, taking frequent screen breaks, keeping your eyes moist, and altering the blue light settings on your devices can all help mitigate the headache-inducing effects of blue light. While not a proven cure, one can use blue light glasses that may provide some comfort.
