Dry eyes in fall: why autumn feels different

Eyes often feel drier in fall because several changes land at once: the furnace switches on for the first time in months, outdoor air turns cooler and drier, wind picks up, and shorter days pull people indoors to screens. Each of those speeds up evaporation from the tear film. Adjusting your heating, blocking wind, blinking more at screens and using a lubricating drop as labeled can help you through the transition.

Dry eyes in fall: what actually changes

Summer air in much of the country is humid, and many people spend the season with windows open or air conditioning on. Fall flips several things at the same time, which is why the change can feel sudden rather than gradual:

• Cooler air holds less water, so the same relative humidity outside means less moisture once it’s warmed indoors.
• The heat comes on, often on the first cold morning, and forced air starts blowing through the house.
• Cold fronts bring gusty, dry wind.
• Sunset comes earlier, so evenings shift to TVs, phones and laptops.
• School, work and holiday planning ramp up screen time and cut sleep.

The first heating days

A furnace that’s been off since spring often does its hardest work in the first chilly weeks, when nobody has pulled the humidifier out of the closet yet. Forced-air heat warms the air without adding water, so indoor relative humidity drops. Dust that settled in the ducts over the summer can also blow through on the first run.

• Change or clean the furnace filter before the first cold night.
• Get a humidifier out and running when the heat comes on, and clean it as directed.
• Check which way the registers blow, and turn any aimed at a bed or favorite chair.
• Set the thermostat a degree or two lower; warmer air dries faster.

Dry eyes in autumn wind

Fall cold fronts often arrive with gusty wind. Wind pulls moisture off the surface of the eye and blows leaf dust and grit around. Raking, leaf blowing, football games and fall hikes all put your face in it.

• Wear sunglasses, ideally wraparound, for yard work and outdoor games.
• Stand upwind of the leaf blower, or wear safety glasses while you run it.
• On a bike or a run, a brimmed cap and glasses cut the wind on your eyes.
• When you come inside, wash your hands before touching your face.

Dry itchy eyes in fall

Plenty of people describe autumn eyes as both dry and itchy. Dryness itself can feel scratchy or gritty. But itching that comes with sneezing, a runny nose or puffy eyelids may have a cause other than dryness, and a lubricating drop isn’t labeled for that. Quell’s Uses line is specific: For use as a protectant against further irritation or to relieve dryness of the eye. If itching is the main complaint, ask a pharmacist or doctor what’s behind it. Eye drops for itchy eyes explains what to look for on labels.

Dry eyes and the season change indoors

Shorter days change routines. Sunset before dinner means more evenings on the couch with a screen, and the end of daylight saving time in early November can scramble sleep for a week or two. Both matter: people blink less while looking at screens, and short sleep tends to leave eyes feeling tired and dry the following morning.

• Take regular breaks: every 20 minutes, look at something across the room and blink slowly.
• Keep phones and tablets slightly below eye level so the lids cover more of the eye.
• Turn on a lamp rather than staring at a bright screen in a dark room.
• Protect your sleep when the clocks change.

A lubricating drop during the transition

Quell is designed to reinforce the tear film’s oil layer to help reduce moisture loss. That oil layer is the part of the tear film that slows evaporation, which is the main thing heated air and wind work against. The label’s directions read: Apply 1 drop 3 times per day in each eye. Follow the handling instruction every time: Do not touch tip of bottle to any surface to avoid contamination.

Fall is also when bottles get left in cars for football tailgates and road trips. The label gives a storage range, Store between 15° to 30°C (59° to 86°F), and early fall afternoons can still heat a parked car past it. Read the full panel on our Drug Facts page.

When autumn dryness is something else

Seasonal dryness tends to ease as you adjust the heat and your habits. If it doesn’t, or if it comes with pain or vision changes, see an eye doctor. The label is clear: Stop use and ask a doctor if you feel eye pain or changes in your vision, if irritation or redness continues, or if the condition worsens or persists for 72 hours. Our self-check can help you think it through, though it’s not a diagnosis. For a list of warning signs, see eye symptoms that need a doctor.
