Why do my eyes feel dry at the end of the day?

Eyes often feel driest in the evening because the day’s exposures add up: hours of screen work that slow blinking, indoor heating or air conditioning, wind or car vents on the commute. By evening the tear film has spent hours fighting evaporation. Spacing drops through the day, Apply 1 drop 3 times per day in each eye, with one saved for later, can help.

Why do my eyes get dry in the evening?

In the morning your eyes have just had hours closed. From then on, every waking hour adds a little more strain: each long stretch of concentration, each room with forced air, each walk into the wind. None of it is dramatic on its own. By 6 p.m. the total is what you feel, which is why the same eyes can be comfortable at breakfast and scratchy by dinner.

Fatigue plays a part as well. Late in the day, people tend to blink less fully and rub their eyes more, and focusing up close for hours leaves the eyes feeling tired on top of dry. Weekends can look completely different: if your eyes feel fine on a Saturday spent outdoors and dry after every workday, that contrast is a strong hint that the workday’s conditions are what’s building up.

Map your day

It helps to see where the hours go. A typical office worker’s day might look like this:

• 7:30 a.m.: shower, coffee, a few minutes on the phone. Eyes feel fine.
• 8:15 a.m.: commute, with the car heater or air conditioning blowing toward the face.
• 9 a.m. to noon: email and documents at a monitor, in a building with forced-air heat or cooling.
• Noon: lunch at the desk, still looking at a screen.
• 1 to 5 p.m.: more screen work and video meetings.
• 5:30 p.m.: commute home, windy walk to the car.
• 7 to 10 p.m.: TV, phone or tablet on the couch, possibly under a ceiling fan.

That’s more than twelve hours of conditions that dry the eyes, with very few real breaks. Writing out your own version for a day or two often shows one or two stretches that are doing most of the damage.

Dry eyes in evening: spread your drops out

A common mistake is using drops early, when your eyes are fine, and having none left when they need them. The label sets three drops a day and leaves the times to you. Try this instead:

• First drop: mid-morning, once screen work is well underway.
• Second drop: early afternoon, after lunch.
• Third drop: late afternoon or early evening, before the commute home or before your evening screen time.

Saving the last one for later in the day covers the hours when your eyes feel worst. Quell is designed to reinforce the tear film’s oil layer to help reduce moisture loss, and that oil layer is what slows evaporation during those long late-day stretches. The tear film’s oil layer explains it.

If your last drop comes before the drive home, keep the bottle in your bag rather than the car, since a parked car can sit well outside the label’s range of Store between 15° to 30°C (59° to 86°F). Give your vision a moment to clear after the drop before you start driving. Some people also find it easier to remember the late dose by pairing it with something fixed, like shutting the laptop or setting an alarm for the end of the workday.

Cut the load in the afternoon and evening

• Take a real lunch away from your screen, outside if the weather allows.
• Turn the car vents toward the windshield or your chest on the drive home.
• In the evening, sit farther from the TV and lower the brightness on phones and tablets.
• Turn the ceiling fan down or off while you’re sitting under it.
• If you read in the evening, use a good lamp and look up from the page every few pages.

Contact lenses at the end of the day

People who wear contacts often notice dryness most in the evening. Quell’s label doesn’t cover use with contact lenses, so talk to your eye doctor about how long you wear them and what drops, if any, are suitable with them. Contact lenses and Quell has more.

When evening dryness is worth a doctor’s visit

Eyes that feel a little tired after a long day are common. See an eye doctor if evening dryness is getting worse over weeks, if it’s affecting your sleep or your ability to drive at night, or if your vision changes. The label puts it plainly: 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. The dry eye self-check can help you describe your pattern, though it’s not a diagnosis.
