Since COVID‑19, students in Pakistan have spent more time than ever on screens for online classes, homework, gaming, and social media. Studies on Pakistani students show a very high prevalence of digital eye strain, with more than 70% reporting symptoms like headache, eye pain, and blurred vision linked to long screen hours.
This guide is written for school, college, and university students in Pakistan as well as their parents and teachers to explain how online classes and gaming affect eye health and how to use screens safely without damaging your eyesight.
How Online Classes and Gaming Affect Your Eyes
Looking at a screen is not the same as looking at a book or the board. It demands more from your eyes and your brain.
Extra strain on focus
Letters and images on screens are less sharp, with lower contrast and more glare, so your eyes have to work harder to keep things clear. Over time, this constant near focus can cause tiredness, ache around the eyes, and difficulty shifting focus from near (screen) to distance (board or road).
Less blinking and more dryness
When you concentrate on a game, movie, or online lecture, your blink rate can drop by almost half. Fewer blinks mean the front surface of the eye dries out more quickly, causing burning, redness, and a gritty or sandy feeling.
Higher risk of myopia (short‑sightedness)
Research on children aged 6–15 shows a significant association between myopia and playing video games, with more myopia in those who play regularly and for longer durations. Combined with less outdoor time, this pattern can lead to an earlier and faster onset of short-sightedness in Pakistani students.
Most Common Symptoms of Digital Eye Strain in Students
Pakistani studies among school and university students found that 70–75% report at least one symptom of digital eye strain when daily screen time is high. Watch for:
-
Headache during or after online classes
-
Eye pain, burning, or a heavy feeling in the eyes
-
Blurred or fluctuating vision, especially when shifting between screen and distance
-
Redness, watering, or dryness
-
Difficulty concentrating or keeping eyes open during long lectures
-
Neck, shoulder, or back pain from poor posture at the screen
If you notice these most days, it is a sign that your screen habits and possibly your glasses number need attention.
How Much Screen Time Is “Too Much” for Students?
Different organizations give slightly different numbers, but they all agree on one point: unlimited screen time is harmful.
International pediatric and eye-health sources commonly suggest:
-
Under 2 years: avoid screen time, except short video calls with family.
-
2–5 years: about 1 hour per day of high‑quality content, with an adult.
-
5–17 years: keep recreational screen time around 2 hours per day (homework and online classes are separate), with plenty of physical activity and proper sleep.
In Pakistan, surveys during COVID‑19 showed many children and teens were on screens for 5–10 hours a day, often with multiple devices and for mixed purposes (classes, homework, gaming, YouTube, social media). That level is clearly risky for eye and general health.
Step‑by‑Step: Safe Screen Habits for Online Classes
You may not be able to reduce online lectures or assignments, but you can change how you use screens.
1. Follow the 20‑20‑20 rule
Every 20 minutes:
-
Look at something at least 20 feet (6 metres) away.
-
For at least 20 seconds.
This relaxes your focus muscles and reduces digital eye strain. Use class transitions, loading times, or teacher breaks to look out of a window or across the room.
2. Sit right, not on the bed
For both online classes and gaming:
-
Use a chair and table, not the bed or sofa.
-
Keep the screen at arm’s length, with the top of the screen at or slightly below eye level.
-
Keep feet flat on the floor, back supported, and shoulders relaxed.
Good posture protects your neck and back, which are commonly affected, along with eyes, in heavy screen users.
3. Fix lighting and reduce glare
-
Do not sit with a bright window behind or directly in front of the screen.
-
Use curtains or blinds to control sunlight glare.
-
Match screen brightness to the room, neither very bright in a dark room nor too dim in bright light.
Glare and poor lighting increase squinting and eye strain during long classes.
Safer Gaming Habits for Pakistani Students
Gaming is fun but tough on your eyes if done wrongly. Studies in Pakistan have linked video game play time with higher rates of refractive errors in children.
Healthier gaming rules:
-
Play in short sessions: 30–45 minutes at a time, then take a proper off‑screen break.
-
Keep the screen at the right distance, not too close to your face.
-
Never game in complete darkness; keep a small room light on.
-
Avoid intense gaming just before sleep; blue light and mental stimulation disturb sleep quality.
If you notice headaches, eye pain, or trouble seeing the board at school, cut down gaming time and book an eye checkup.
Outdoor Time: Your Natural Protection Against Eye Problems
Eye and pediatric experts emphasize that daily outdoor play protects against myopia and balances the effects of indoor screen time.
Aim for:
-
At least 1–2 hours of outdoor activity most days (walking, sports, cycling, simple play), where safe.
-
Looking at distant objects (trees, buildings, sky) to give your eyes a real break from constant near focus.
For many Pakistani students, simply replacing a part of daily gaming or scrolling with outdoor time can make a visible difference in comfort and mood.
When Students Should See an Eye Specialist in Pakistan
You should visit an eye specialist or eye clinic (in Lahore, Karachi, Islamabad, or your nearest city) if:
-
You have frequent headaches or eye pain during or after online classes.
-
You struggle to see the board in class after a period of heavy screen use.
-
Your eyes remain red and dry even with breaks.
-
Your grades are dropping because you cannot see clearly or concentrate.
Studies among Pakistani students show that refractive errors (needing glasses) are very common, and headaches, blurred vision, and eye pain are strongly associated with both screen time and uncorrected eyeglass numbers. A detailed exam can clarify what’s going on.
A proper student eye checkup should include the following:
-
Vision testing for distance and near
-
Refraction to check your glasses number
-
Examination of the front of the eye for dryness or allergy
-
A retinal check if there are risk factors or concerning symptoms
Role of Parents and Teachers in Safe Screen Use
Parents and teachers in Pakistan can greatly reduce digital eye problems for students by:
-
Setting clear rules on recreational screen time (gaming, social media, random videos).
-
Encouraging children and teens to use the 20‑20‑20 rule during study.
-
Ensuring that devices are used in common spaces, not alone in dark bedrooms.
-
Supporting regular outdoor activities and sports.
-
Arranging or recommending annual eye checkups, especially after long periods of online learning.
Simple family and school policies often work better than frequent scolding or last‑minute panic before exams.
Quick Checklist: A Student’s Daily Screen‑Safety Plan
You can use this as a personal checklist:
-
During classes: I follow the 20‑20‑20 rule and sit at a desk, not on the bed.
-
For gaming and videos: I limit my fun screen time and take breaks between sessions.
-
Environment: My room has good lighting, and my screen is at the right distance and height.
-
Health: I get outdoor time most days and sleep on time, without late‑night scrolling.
-
Eye care: I have had a proper eye checkup in the last 1–2 years or will book one if I have symptoms.
Final Thoughts: Enjoy Screens, But Protect Your Sight
Online classes and gaming are now part of student life in Pakistan, but they do not have to damage your eyes. Studies clearly show a link between long, unbroken screen time and digital eye strain, headaches, and other eye problems in Pakistani children and students.
By balancing online learning and gaming with smart habits, regular breaks, correct posture, good lighting, outdoor activity, and timely eye checkups, you can enjoy technology while keeping your vision clear and comfortable for the future.
