What Is Digital Eye Strain?

Digital Eye Strain (DES), also known as Computer Vision Syndrome, is a group of vision and comfort issues caused by extended digital device use.

When you focus on screens for long periods:

• You blink less frequently (from 15–20 times/min to 5–7).

• Your eyes dry out faster.

• Muscles controlling focus and alignment fatigue.

• Blue light scatters more inside the eye, causing glare and reduced contrast.

  
  

Common Symptoms

• Eye fatigue or heaviness

• Burning, itching, or watery eyes

• Headache around temples or behind eyes

• Difficulty focusing between near and far

• Neck and shoulder stiffness

• Increased sensitivity to light

If these symptoms appear daily, especially after device use, it’s time for a comprehensive eye strain evaluation.

Why It’s Worse in Mumbai

Urban life adds layers to digital stress:

• Air-conditioning & pollution dry out eyes faster.

• Long commutes increase exposure to glare.

• Remote work & online classes mean near-constant screen use.

• High humidity & poor sleep worsen eye fatigue.

That’s why preventive eye care is essential, not just treatment after damage occurs.

Blue Light and Its Impact

Digital screens emit high-energy blue light (400–490 nm) that penetrates deeper into the eye.

While not all blue light is bad, prolonged exposure can:

• Increase eye strain and glare sensitivity

• Disrupt melatonin and sleep cycles

• Contribute to retinal oxidative stress over years

Do Blue Light Glasses Help?

Yes, when prescribed correctly.Blue-filter lenses reduce glare, improve contrast, and help your eyes stay relaxed during long hours of digital work.

At I-Sight Eye Care, we recommend optically balanced blue-block lenses designed for your specific screen distance (office, mobile, or mixed use).

Children and Myopia: A Growing Concern

The pandemic years triggered a surge in childhood myopia (short-sightedness) especially in Mumbai.

Why It’s Rising

• Prolonged near-screen focus

• Reduced outdoor playtime

• Excessive indoor lighting and screen glare

Studies show children spending less than 90 minutes outdoors daily are at higher risk of developing progressive myopia.

Prevention and Management

At I-Sight Eye Care, we focus on early detection and control through:

• Myopia control lenses (Defocus Incorporated Multiple Segments)

• Low-dose atropine therapy

• Outdoor activity counselling

• Regular eye growth tracking every 6 months

Preventing high myopia isn’t cosmetic, it protects against future risks like retinal detachment, glaucoma, and macular damage.

Lifestyle Tips to Reduce Digital Eye Strain

👁️ The 20-20-20 Rule

Every 20 minutes, look 20 feet away for 20 seconds. It resets eye muscles and prevents fatigue.

💧 Blink Intentionally

Conscious blinking restores your tear film and reduces dryness.

💻 Optimize Your Workspace

• Keep screens 20–24 inches from your eyes.

• Adjust monitor so top line is at or slightly below eye level.

• Reduce glare with anti-reflective filters.

• Maintain proper lighting, not too bright, not too dim.

🕶️ Use Blue Light Glasses

Especially useful for professionals, students, and gamers.

🥗 Support Eye Health Nutritionally

Eat foods rich in omega-3s (flaxseed, walnuts, salmon) and lutein (spinach, kale, corn).

☀️ Get Outdoors

For kids and adults alike, at least 90 minutes of natural daylight daily helps maintain healthy eye growth and rhythm.

Q: Can children develop digital eye strain?

Absolutely. Kids using screens for school or gaming are equally vulnerable and may develop early myopia.

Q: Can digital eye strain cause permanent damage?

It rarely causes permanent harm, but chronic strain accelerates dryness and myopia progression if ignored.

Adults: once a year.

Children: every 6–12 months, especially if they use digital devices daily.
