Do blue light glasses actually work for headaches?
Blue light glasses can help reduce the effects of blue light on your eyes and may help ease digital eye strain, but they are not an ultimate solution to headaches—including headaches caused by digital eye strain.
In short, blue light blocking glasses were not proven to be any better for eye strain than regular clear lenses. Unfortunately, this means that they won't help with eye-strain-related headaches. It should be noted that this study was conducted on blue blockers only — not on migraine and light sensitivity glasses.
Computer glasses with clear lenses block about 20% of blue light (depending on manufacturer), which can be enough to limit the harmful effects of blue light. Better blue light blockers have yellow, orange, or amber lenses.
The evidence for them, though, has largely been lacking. And a new review of 17 studies adds to a growing consensus that they probably don't prevent or relieve eye strain. The phrase blue light refers to a range of wavelengths of light that are all around us — the sun emits it and so do screens.
BOTTOM LINE: 9 out of 10 patients find relief with precision-tinted glasses for migraine. The headline says it all. After more than five years in business, nearly 90% of the tens of thousands who have used precision-tinted TheraSpecs glasses have experienced relief for their migraine-related light sensitivity.
Research shows TheraSpecs® migraine glasses and migraine sunglasses relieve painful light sensitivity better than regular sunglasses and also reduce the number of migraine attacks all without the cost and side effects associated with medications.
Rose-tinted glasses for migraines are an FL-41 lens designed to help patients with chronic migraines or photophobia. In 1991, children diagnosed with migraines wore a red-tinted FL-41 lens for four months. The study revealed the migraine frequency had improved from 6.2 per month to 1.6 per month.
A major blue cut lenses disadvantage is that the lenses have a bluish reflection. The lenses of blue light filter glasses exhibit a little bluish sheen since they are designed to reflect this blue light. This isn't something you'll notice when you're wearing them, but it's a feature that others will notice.
“During the day, we need to receive the blue light of the sun to regulate our circadian cycle. If we block it, we can experience drowsiness and sleep disorders.” The review also found no evidence that blue light filtering lenses protect against damage to the retina, the light-sensitive tissue at the back of the eye.
Blue-light glasses can be one way to ease digital eye strain in either case. This specialized eyewear filters blue light and increases contrast, allowing you to focus more easily and preventing eye strain. Get computer protective glasses with yellow lenses if you wish to enjoy viewing digital devices for long periods.
Can blue light cause headaches?
For a person with healthy eyes, blue light exposure from a variety of sources such as screens and sunlight can lead to eye strain, which often results in a constellation of symptoms like headaches. Longer duration of exposure and the brightness of the light source also play a role in the onset of headache symptoms.
At high intensity of light—as in a well-lit office—nearly 80 percent of patients reported intensification of headache with exposure to all colors but green. Unexpectedly, the researchers found that green light even reduced pain by about 20 percent.
Migraine glasses have special tints applied to the lenses. This tint helps block out specific types of light known to cause migraines or make them worse, such as blue light and UV light. The tints can vary in color and darkness depending on your specific needs.
Because your eyes consist of a nerve called the optic nerve, any inflammation from strain can lead to pain that travels from your eyes to your brain. If you find yourself experiencing frequent headaches that don't subside after taking the appropriate steps to relieve eye strain, you likely need glasses.
Eye-related headaches aren't associated with other symptoms like nausea or vomiting. In these cases, you may have a primary headache disorder. However, eye strain is one of the signs that you may need glasses. Eye strain can lead to headaches in individuals, which may need to be remedied with glasses.
TheraSpecs are the only computer glasses designed specifically for migraine sufferers. They block light from above and the sides and are ultra-lightweight and flexible to minimize pressure on already-sensitive heads.
Blue light glasses are a popular suggestion when someone experiences headaches and other symptoms related to digital eye strain, because they effectively filter out blue light. While they can help reduce symptoms of eye strain, there may be other reasons you're experiencing headaches.
Blue light-filtering lenses typically block only about 10% to 25% of blue light, and screens don't emit much anyway, said Rosenfield, who wasn't involved with the new research. “The sun is far and away the biggest source of blue light.
If you feel blue light glasses reduce your eye strain or help you function better in front of a digital screen, then you can wear them whenever you want for a long as you want. You can forget to take them off or wear them all day just because you like them, and you're totally safe to do so.
The analysis of the trials showed that there is no short-term advantage to using blue-light-filtering spectacles for reducing vision fatigue, compared with standard clear lenses. Only one of the studies examined the impact of blue-light-filtering glasses on eyesight, and it suggested that there was little to no effect.
Do blue light glasses work for driving at night?
While they're not the only option for night driving, they are effective in increasing contrast and reducing glare. Blue light glasses for night driving can also help reduce eyestrain from extended screen time, making them great for gamers or anyone who spends hours on their computer daily.

Blue light can cause eye strain, which results in less focus and brain fog. Excessive exposure to blue light can cause headaches.
Exposure to both blue and red forms of light can actually increase headache pain. If a person has a tendency to experience chronic headaches after working at their desk all day, the problem may not be their workload or stress from the day's events.
People who have tension headaches often complain of a band of pain across their forehead, or pressure on either side of the head. The pain is tiring, but not as severe as migraine. Migraine, on the other hand, usually hurts worse on one side of the head.
