"My Eyes Feel Dry and Tired": Why Office Workers Shouldn't Ignore Digital Eye Strain

The Ultimate Guide to Improving Eye Health by BGN Eye Clinic Jamsil

Hello, this is BGN Eye Clinic Jamsil.

Lately, when meeting our corporate patients in the clinic, there is one thing we hear most often:

"I stare at a computer screen all day, so my eyes feel dry and tired. I also have trouble focusing."
"I've tried following tips online to improve my vision, but the relief is only temporary. It doesn't fix the root problem."

Office workers, developers, and designers who spend over 8 hours a day in front of a monitor almost universally experience these symptoms. Medically, this is not just simple fatigue. It can be an early sign of Visual Display Terminal (VDT) Syndrome, which requires special attention.

"Text Looks Overlapped"... Office Worker Eye Strain, a Warning Sign of Dry Eye Syndrome

A few days ago, a patient in their mid-30s working in marketing came in for an eye exam. They were suddenly frightened because their vision had become blurry and text appeared to overlap.

"When I look away from the monitor, my eyes blank out and can't focus."
"By evening, my eyes are so exhausted that I can't even concentrate during meetings."

This patient had a daily routine of looking at screens for over 12 hours. When we focus on a screen, our blink rate unconsciously drops by a third. This destroys the lipid layer that protects our tears, worsening into chronic dry eye syndrome. If fatigue accumulates and the eye muscles remain tense, it can cause shaky vision and even headaches.

Digital Eye Strain (VDT Syndrome): Your Eyes Are Exhausted Too

VDT Syndrome, caused by the use of digital devices like smartphones and tablets, goes beyond a simple feeling of dryness. In severe cases, it causes an aching pain behind the eyes and dizziness.

Could I Have VDT Syndrome? Check the Main Symptoms

• • Eyes feel dry and tired (accompanied by frequent redness)
• • Vision becomes blurry and text overlaps in the afternoon
• • Frequent headaches and a feeling of heavy eyelids
• • Eyes water and sting especially at night or on windy days

If you experience shaky vision or a foreign body sensation even after getting off work, it may be a sign that your tear film balance has already collapsed.

5 Daily Eye Health Rules for Office Workers

A daily home care routine is just as important as medical treatment. Here are 5 of the most effective eye health tips you can start practicing right now.

1. Practice the 20-20-20 Rule

Every 20 minutes, look at something 20 feet (about 6m) away for at least 20 seconds. It helps to relax your eye muscles by looking out a window or down the office hallway.

2. Blink Consciously and 'Completely'

Consciously repeat the action of gently closing your eyes for 2-3 seconds and then opening them. This facilitates the secretion from the meibomian glands (oil glands) that coat the tear film.

3. Position Your Monitor Below Eye Level

If your monitor is higher than your eye level, a larger area of your eyeball is exposed to the air. Adjust it so that it sits about 15-20 degrees slightly below your eyes.

4. Manage Indoor Humidity and Lighting

If the lighting is too bright or too dark, your irises overwork, leading to fatigue. Adjust the ambient lighting to a comfortable level and use a humidifier to maintain indoor humidity at 40-60%.

5. Use Preservative-Free Artificial Tears

Don't force yourself to endure the dryness. You should protect your eyes by using preservative-free, single-use artificial tears (such as hyaluronic acid) whenever you experience symptoms.

What If Basic Habits Aren't Enough? You Need a Comprehensive Examination

If the "my eyes feel dry and tired" symptoms persist even after following these rules, it may not be simple fatigue but a condition requiring medical treatment.

Q. What if my eyes still feel dry even after using eye drops?

A. There is a high probability of "evaporative dry eye," where tears evaporate too quickly. At BGN Eye Clinic Jamsil, we accurately analyze tear break-up time and the degree of oil gland blockage through comprehensive meibomian gland examinations.

Q. What kind of treatments do eye clinics offer?

A. Depending on the test results, we fundamentally improve the tear environment by performing treatments like Intense Pulsed Light (IPL) therapy to melt and express hardened oils, or specialized punctal occlusion.

Knowing your exact eye condition is the first step in any treatment. Once the tear film balance is broken, it is difficult to restore. Now is the best time to take care of your eye health.
