Tired eyes that don’t improve with rest are often a sign of dry eye disease, not fatigue. Dry eye happens when your eyes don’t make enough tears, or when your tears evaporate too quickly to stay comfortable. Common signs include burning, grittiness, blurry vision that clears when you blink, and eyes that feel exhausted by midafternoon even after a full night’s sleep. At DLV Vision, our clinical team regularly sees patients across Ventura County and Los Angeles County who assume screen fatigue explains their symptoms, when dry eye is the actual cause.
Quick Takeaways
- Dry eye means your eyes lack enough quality tears to stay lubricated and comfortable.
- Key symptoms: burning, stinging, grittiness, redness, light sensitivity, and blurry vision that improves with blinking.
- Dry eye is common and treatable, but untreated cases can damage the eye’s surface over time.
- Treatment ranges from artificial tears to prescription drops and in-office procedures.
- See an eye doctor if symptoms last more than a few weeks or interfere with daily activities.
What Causes Dry Eye?
Dry eye develops when your tear film becomes unstable. Extended screen time reduces your blink rate, which speeds up tear evaporation. Age, contact lens wear, indoor heating and air conditioning, certain medications, and the dry, windy climate common in Los Angeles California all raise your risk. According to the American Academy of Ophthalmology, dry eye is one of the most common reasons patients visit an eye doctor.
What Are the 5 Signs Tired Eyes Might Actually Be Dry Eye?
Many patients describe their eyes as “tired” for months before learning the real cause is dry eye. Here are the five signs our team hears most often at DLV Vision:
- Your eyes feel heavy or strained by early afternoon, and rest doesn’t fix it.
- Your vision blurs and then clears when you blink — a sign of an unstable tear film, not a prescription change.
- Your eyes burn, sting, or feel gritty, especially in wind or air conditioning.
- Your eyes water excessively. This happens when irritated eyes overproduce watery tears to compensate for poor tear quality.
- You feel like something is stuck in your eye, without an actual object present.
Left untreated, chronic dry eye can damage the eye’s surface and make daily tasks like driving or screen work more uncomfortable over time.
When Should You See an Eye Doctor?
See an eye doctor if symptoms last longer than two weeks, worsen despite over-the-counter drops, or interfere with reading, driving, or screen work. Seek care sooner for eye pain, sudden vision changes, or discharge.
How Is Dry Eye Diagnosed and Treated?
An ophthalmologist diagnoses dry eye through a comprehensive eye exam that measures tear production and checks the eye’s surface for irritation. The National Eye Institute (nei.nih.gov) notes that accurate diagnosis matters because dry eye symptoms can overlap with other eye conditions.
Mild cases often respond to preservative-free artificial tears and simple habit changes, like screen breaks. Moderate to severe cases may need prescription anti-inflammatory drops, punctal plugs, or in-office procedures. Patients considering LASIK Eye Surgery at DLV Vision should also have a dry eye evaluation first, since untreated dry eye can affect surgical planning.

Frequently Asked Questions
Can dry eye cause blurry vision?
Yes. Dry eye disrupts the tear film that keeps your eye’s surface smooth, causing vision to blur and clear again after blinking.
Is dry eye the same as eye allergies?
No. Dry eye results from insufficient or unstable tears, while eye allergies involve an immune response to irritants. A comprehensive eye exam can identify the correct cause.
Can screen time cause dry eye?
Yes. Screen use significantly reduces your blink rate, allowing tears to evaporate more quickly and leading to dryness, irritation, and eye fatigue.
Will over-the-counter drops fix dry eye?
Artificial tears can help relieve mild, occasional dry eye symptoms. However, persistent or worsening dryness often requires a comprehensive eye exam to determine whether prescription treatment or other therapies are needed.
