If you work long hours on a laptop, you may know the feeling: burning, gritty or watery eyes by evening, blurred vision that comes and goes, and headaches. This is often called digital eye strain, and dry eye is a big part of it.
Why screens dry your eyes
When we concentrate on a screen, we blink far less often and less completely. The tear film that protects the surface of the eye evaporates faster. Air-conditioned offices, fans and long commutes in traffic and dust add to the problem.
Simple habits that help
- Follow the 20-20-20 rule. Every 20 minutes, look at something 20 feet away for 20 seconds.
- Blink on purpose. Take a few slow, full blinks during breaks.
- Set up your screen. Keep it an arm’s length away and slightly below eye level.
- Reduce glare. Match screen brightness to the room and avoid sitting under or facing a bright window.
- Avoid direct airflow. Angle AC vents and fans away from your face.
- Drink water through the day.
- Wear your current glasses. An outdated prescription makes your eyes work harder.
About eye drops
Preservative-free lubricating drops can ease symptoms. Avoid drops that ‘remove redness’ for regular use, and never use steroid drops without a prescription, as they can cause glaucoma and cataract.
When to see an eye doctor
- Symptoms continue despite these changes
- Your eyes are red, painful or sensitive to light
- Your vision stays blurred after blinking
- You wear contact lenses and your eyes feel uncomfortable
A comprehensive eye check-up can find the cause and the right treatment. Our HSR Layout and Hosa Road clinics are close to the Outer Ring Road and Electronics City tech parks.
Frequently asked questions
Do blue light glasses prevent eye strain?
There is no strong evidence that blue light from screens damages the eyes or that blue-filter lenses reduce strain. Breaks and blinking help more.
Can dry eye be cured?
Dry eye is often long-term, but treatment can control symptoms well.
