Dry eyes may sound like a minor inconvenience. However, persistent dryness and irritation can significantly affect our quality of life by making simple, everyday tasks, like computer work, reading, and driving more difficult.
Researchers are still exploring the connection between dry eyes and headaches. Currently, it appears as though headaches develop as a secondary symptom of dry eye in several ways:
- Eye strain and visual fatigue
- Nerve irritation
- Light sensitivity
- A feedback loop from underlying systemic factors.
A dry eye consultation is the first step towards long-lasting relief from symptoms. During this, your eye doctor will assess the severity of dryness, and the health of your tear film, and evaluate your symptoms to develop a therapy plan tailored to your unique concerns.
Defining Dry Eyes
Dry eye disease is a chronic condition that develops when the eyes don’t produce enough tears or quality tears to provide adequate moisture or when tears evaporate too quickly from the eye’s surface.
Beyond helping us express how we feel, tears have a functional purpose. They help maintain eye health by nourishing them, protecting the corneal surface from debris and other irritants, and maintaining a smooth optical surface for clear vision.
Three distinct layers make up the tear film. A problem in any one of them creates instability in the tear film, leading to dry eyes and symptoms that include:
- Sensitivity to light
- Eye fatigue
- Red eyes and inflammation
- Blurry or fluctuating vision
- Burning, stinging, or a gritty sensation
Several contributing factors can destabilize the tear film and lead to dry eyes. Common causes include:
- Aging, as tear production naturally declines as we grow older.
- Exposure to windy, smokey, dry climates, and even air conditioning.
- Extended work on digital screens, reduces how frequently we blink, preventing tears from dispersing.
- Improper contact lens care or overusing the lenses.
- Certain medications like antihistamines, antidepressants, or blood pressure drugs.
Dealing with persistent dryness is frustrating, but beyond irritating symptoms, managing dry eyes is essential for maintaining good eye health and vision. Leaving dry eyes untreated increases the risk of developing severe eye conditions, leading to adverse effects on our eyes, including vision loss.
Exploring the Link Between Headaches & Dry Eyes
It’s unlikely that dry eyes directly cause headaches, and while current studies do see a definite link, further research is still necessary.
Currently, it’s understood that headaches develop as a secondary symptom of dry eyes, triggered by discomfort:
- Eye Strain and visual fatigue: Dry eyes force the eyes to work harder to focus on visual tasks. Constantly adjusting to blurry or fluctuating vision or compensating for discomfort strains eye muscles. This contributes to tension headaches, which are particularly common for those who spend long hours on computers or digital screens.
- Nerve irritation: The eye’s cornea, is innervated with sensory nerves. When the eye’s surface is dry, it can irritate these nerves directly, sending pain signals to the surrounding orbital regions, and leading to a headache.
- Light sensitivity: Sensitivity to bright light is common in those with dry eyes. Bright light or glare can overstimulate the trigeminal nerve, one of the major nerves connected to the face and head, potentially resulting in headaches.
- Underlying systemic factors: Migraines or sinus pressure can create a feedback loop where dry eye discomfort intensifies headache pain. Certain medications used to treat chronic headaches may worsen dry eye symptoms as a side effect. This relationship results in a cycle where both symptoms exacerbate each other.
Managing Dry Eyes
There is no cure for dry eyes, but this condition–and its subsequent secondary symptoms like headaches–can be managed. A combination of advanced therapies and at-home remedies helps relieve symptoms and improve your quality of life.
Advanced Therapies
For those with chronic or severe dry eyes, advanced therapies go beyond traditional at-home remedies by tackling the root cause of dryness, offering longer-lasting relief from symptoms.
- TearCare: This therapy uses heat and gentle pressure to unblock oil glands along the eyelids, which produce oils necessary for a stable tear film. TearCare restores the tear film’s natural balance and reduces dry eye symptoms significantly over time.
- Punctal Plugs: These tiny devices are inserted into the tear ducts to reduce tear drainage, helping retain moisture on the eye’s surface for a longer period.
- Low-Level Light Therapy (LLLT): This non-invasive treatment uses light stimulation to improve circulation in the oil glands along the eyelids. This process reduces inflammation and helps restore tear production.
- Intense Pulse Light (IPL) Therapy: IPL uses pulses of light to treat meibomian gland dysfunction (MGD), a common cause of dry eye. The light reduces inflammation, clears blockages, and improves oil production in the glands, helping restore the natural tear film and providing long-lasting relief from dry eye symptoms.
At-Home Remedies
These at-home strategies are great for those with mild to moderate dry eyes, and can also be combined with advanced therapies to maintain and prolong their results.
- Artificial tears: A common over-the-counter solution to dryness, these eye drops provide immediate relief for mild symptoms by mimicking the natural composition of tears. Opt for preservative-free formulas if you plan on using these eye drops frequently.
- Warm compress mask: Gently heat a cloth with warm water, ring out the excess, and place it over your eyelids. Use your fingertips to massage the oil glands along the eyelids, improving the oil secretion necessary to restore the tear film.
- Adjust your screen habits: Follow the 20-20-20 rule to reduce eye strain and encourage blinking during long periods of screen time. Every 20 minutes, take a 20-second break and look at something 20 feet away.
- Stay hydrated: Adults should aim to drink at least 8 glasses of water daily. Staying hydrated helps the tear glands function effectively and improves tear film quality.
- Use a humidifier: While dryness isn’t really a problem in Longview, our hot and humid summers require air conditioning. This creates a dry, arid environment. Use a humidifier indoors to help maintain moisture levels in the air and reduce dry eye symptoms.
Restore Comfort & Clarity
While experts continue to explore the connection between dry eyes and headaches, current research supports dry eyes acting as a trigger for mild headaches.
Addressing the underlying dryness may offer significant relief if you regularly experience headaches alongside dry eye symptoms.
