Dry, gritty-feeling eyes are one of the most common everyday eye complaints, and the causes are usually more mundane than people expect.

Common everyday triggers

• Screen time: We blink less often when focused on a screen, which lets the tear film evaporate faster.
• Dry air: Air conditioning, heating, and low-humidity climates all speed up tear evaporation.
• Contact lenses: Extended wear can reduce the amount of oxygen and moisture reaching the eye’s surface.
• Eyelid buildup: When the lash line collects oil, makeup, or debris, it can affect how evenly the tear film spreads.
• Age and hormones: Tear production naturally changes over time and can vary with hormonal shifts.

Everyday habits that can help

Simple changes often make a noticeable difference: taking regular breaks from screens (the 20-20-20 rule—every 20 minutes, look at something 20 feet away for 20 seconds), using a humidifier in dry indoor air, and keeping the eyelid margin clean with a gentle daily wipe or cleanser.

When it’s more than “everyday”

Occasional dryness is normal. But if your eyes are persistently red, painful, sensitive to light, or the grittiness doesn’t improve with simple habit changes, it’s worth having an eye care professional take a look. Dryness can sometimes point to an underlying condition that benefits from a proper diagnosis rather than guesswork.
