You know it when you feel it. You walk into an office or retail store, and whether it happens immediately or after a few minutes, it’s unmistakable. The fluorescent fixtures overhead are beaming out their flickering, harsh, and (at least to you) excessively bright light — and here comes trouble.
No matter what others believe, your sensitivity to fluorescent light isn’t all in your head. You can feel its effects, and it really does impact your life. Consider what John had to say about spending his days under fluorescent light:
“I work at a hospital with all fluorescent lighting and white walls. I was getting dizzy and headaches at work on a daily basis.”
In this article we’ll discuss why your eyes might be sensitive to fluorescent lights, and how to recognize the potential symptoms. We’ll talk about how sensitivity to fluorescent lighting relates to migraines, and give you some strategies that may reduce your exposure.
Why Are My Eyes Sensitive to Fluorescent Lights?
One reason you might have trouble with fluorescent lighting is the spectrum of light it puts out.
While sunlight produces a full spectrum of light, artificial light (such as fluorescent) produces a very limited spectrum. This narrow spectrum consists of primarily blue light. Blue light is shorter wavelength and scatters easily. This may be why it’s more troublesome to people in general than other types of light. Without a full spectrum to balance it out, that blue light can take its toll.
Another reason you may have sensitivity to fluorescent light is photophobia, or light sensitivity. While many people associate the word “phobia” with irrational fears, photophobia is a bona fide medical condition describing extreme sensitivity or intolerance for bright lights, or certain types of light. And the light emitted from fluorescent fixtures happens to be one of the main aggravators.
Photophobia isn’t incredibly common, but it does affect millions of people in the United States. It has a variety of causes. It may be a diagnosed medical condition, which means it’s something you’ll probably always deal with. But there are also several things that may cause more acute cases of photophobia, which may subside or stay with you long-term.
These causes include:
- Acute inflammation in the eye (iritis or uveitis)
- Eye infection, such as pink eye (conjuntivitis)
- Poor fit or irritation from contact lenses
- Abrasion / scratch or ulcer in the cornea
- Dry eyes
- Traumatic brain injury
- Eye injury or disease (such as glaucoma)
- Recent eye surgery
- Dilated eye exams
- Side effects of some medications
- Migraine headaches
Even if you have no identifiable cause for photophobia, you could still be dealing with it as a medical condition. Its hypersensitivity to light may cause you to experience symptoms such as:
- Dry eyes
- Excessive tearing
- Involuntary blinking
- Involuntary squinting
- Burning sensation
Possible Symptoms of Fluorescent Light Sensitivity
At Axon Optics, we conducted a survey specifically about fluorescent lighting to get a better understanding of how fluorescent lights might affect migraine sufferers. We gathered over 1,600 responses. Our survey found that 33% of the participants have severe limitations when trying to function under fluorescent lighting. So if you experience unpleasant or even debilitating symptoms when exposed to fluorescent lights, you are definitely not alone!
Under fluorescent lights, you may experience any or all of the above symptoms of photophobia. But there are other symptoms that seem to be related specifically to fluorescent lighting exposure that you may also be feeling, such as:
- Eye strain
- Eye pain or inflammation
- Blurry vision
- Difficulty concentrating
- Vertigo or dizziness
- Difficulty focusing or reading
- Shortness of breath
- Feeling depressed
- Sleep disturbances
- Hormonal disruptions
Fluorescent Light, Headaches & Migraines
When it comes to light sensitivity, the type of light makes a difference.
Brightness of a given environment has an effect, but so does the wavelength or color of that light. As we discussed earlier, blue light is more problematic than other types of light, and may cause eye strain and headaches. Fluorescent lights (along with devices like computers, TV screens, and smartphones) are a primary source of blue light.
There are two reasons why fluorescent light causes headaches in some individuals. The first is that fluorescent light emits a large amount of blue light, which is problematic for light-sensitive people. And second, fluorescent light has a fast (virtually unnoticeable) flicker, which can also trigger a migraine.
In the survey referenced above, we found that 56% say that bright lights provoke headaches for them — and fluorescent lighting definitely qualifies as bright. 73% report that bright light is very unpleasant during a headache. And the problem is bad enough that 85% of participants say they actually wear sunglasses to decrease their headaches (which is a bad idea…learn why here).
7 Ways to Relieve Fluorescent Light Sensitivity
Fluorescent lighting is inexpensive and efficient, making them the ideal choice for many businesses. This is why if you work in a retail setting or office building, you probably spend 8 or more hours per day being bombarded by fluorescent light.
Since you can’t very well go around turning all the lights off, you have to figure out how to deal with your situation.
Here are a few strategies you might consider.
Wear Glasses for Light Sensitivity
Sure, you could wear sunglasses indoors, but that could end up dark adapting your eyes and making your problem worse. This is why glasses specifically designed for light sensitivity are a better choice. These glasses block the blue spectrum of light which is most troublesome, but let the rest of the light in. They’ve been shown effective in clinical surveys, and more than a thousand users have used them with good results.
Those include Axon Optics customer John, whom we quoted earlier about working in a hospital under fluorescent lighting all day. He continues:
“After realizing that it was the lighting that was causing me a headache, I did some research online after becoming pretty desperate for some relief. I ordered a pair, and since then they have worked great. I haven’t had any dizzy spells or nearly as many headaches if any.“
In fact, in a HIT-6 headache impact study we conducted, we found that 85% of Axon Optics users for light sensitivity have had great results using the glasses when they’re under fluorescent lights. This data is specific to Axon Optics. And the specialized tint we use has been shown to improve blink frequency and other functional limitations in people with light sensitivity.
Take Frequent Breaks
When the fluorescent lighting at work starts to bother you, put on your sunglasses and get outside for a bit. This will get you out of the irritating blue-heavy spectrum of light in the office into the broader spectrum of sunshine. And hey, you might also find yourself with a sunnier attitude when you return.
Use Physical Barriers
When it’s behind a “shade” or cover, fluorescent lighting is less irritating.
In your office or cubicle, try draping some fabric or even setting up an umbrella to give you some shade. It might look a little strange, and your employer might have to approve it, but it can really help. Just make sure that what you’re doing isn’t too bothersome to the people around you.
Put on a Hat
If it’s okay with your company dress code, a wide-brimmed hat can shade your eyes and bring some relief. (But it could cause a whole different problem in the form of “hat hair.”)
Talk to your employer about adding some dimmers. If the lights in your office or over your desk don’t affect other people, you may have some level of control. Then you can add a regular lamp with an incandescent bulb if you need extra light.
Unscrew Fluorescent Bulbs
If your employer will allow it (you probably want to ask first), you can try unscrewing the fluorescent bulbs above your desk, or see if the maintenance crew can replace those particular bulbs with burned-out bulbs to lessen your exposure.
Use Natural Light
If you can, move your desk closer to a window or overhead skylight. Take a look around these potential areas first, to make sure you won’t be exacerbating photophobia by being exposed to glare from nearby water or buildings.
If you can get more natural light, maybe you can turn the fluorescent ones off or balance out the blue spectrum light with full-spectrum sunshine.
Sensitivity to Fluorescent Light Doesn’t Have to Keep You in the Dark
Your challenges with this type of lighting may be due to ongoing or acute photophobia. Or, they may be isolated to sensitivity to fluorescent lights. In any case, precision-tinted glasses and the strategies above can help you ease your discomfort in a non-invasive way. Since they’re easy to take on and off and don’t affect the people around you, Axon Optics eyewear may be the easiest method to reduce your symptoms. We hope they help you deal with fluorescent light sensitivity without staying in the dark.
