Every year between February and June, our paediatric clinics fill up with the same complaint: "He says his eyes are paining while studying." Most of the time it is genuine eye strain from long hours of close work, and it settles with simple changes. Sometimes it is the first time anyone has noticed that the child cannot see the blackboard. The two look almost identical from the outside, which is why parents should know what separates them.
What ordinary exam strain looks like
A child studying for six or seven hours a day is asking their focusing muscles to hold a near target far longer than they were built to. The result is predictable and harmless in itself:
- Aching or heaviness around the eyes and forehead after long study sessions, easing within 15 to 20 minutes of stopping.
- Words going slightly blurry after an hour of reading, then clearing when they look up.
- Rubbing the eyes in the evening but not in the morning.
- Wanting to lie down or close the eyes for a few minutes, then carrying on fine.
The pattern that matters here is recovery. Ordinary strain builds up through the day and disappears with rest and sleep. A child who wakes up fresh and only struggles after long stretches of work is usually just tired.
The complaints that are not just strain
Some things should not be explained away as exam pressure. Bring the child in for a proper eye test if you notice any of these, whether or not exams are on:
- Moving closer. Sitting nearer the TV than before, holding the phone close to the face, asking to be moved to the front bench.
- Squeezing the eyes shut or half-closing them to read something at a distance. This is the classic sign of uncorrected myopia.
- Headaches in the morning, or headaches on days with no studying at all.
- One eye drifting inward or outward, especially when the child is tired. Occasional drifting in a school-age child is not normal and needs assessment for squint.
- Covering or closing one eye to read, or tilting the head consistently to one side.
- Skipping lines, losing place while reading, or double vision when reading but not at distance. This points to a focusing or eye-teaming problem rather than a simple power problem.
- A sudden fall in marks in a child who was doing fine, particularly in subjects with board work.
A child can have significant myopia in one eye and near-perfect vision in the other, and function well enough that nobody notices for years. They do not complain, because they have nothing to compare against. This is exactly the situation a school screening or a routine test catches and a parent cannot.
What actually helps during exam months
Most of what is sold for eye strain does not do much. What genuinely helps is unglamorous:
- Break the block. Roughly every 30 to 40 minutes of study, two minutes looking out of a window at something far away. It relaxes the focusing muscle, which is the muscle that is actually complaining.
- Light on the book, not on the screen. A desk lamp positioned so the page is well lit without glare, plus room lighting on. Studying with one small lamp in an otherwise dark room forces the eyes to work across a harsh contrast difference for hours.
- Distance and posture. Reading material at about 35 to 40 cm, not 15 cm. Children who habitually read very close often turn out to have uncorrected power.
- Outdoor time, even in exam season. Time spent outdoors in daylight is one of the few things shown to slow the progression of myopia in children. Half an hour of actual daylight is worth protecting even in the last week before an exam.
- Sleep. Focusing fatigue is far worse in a child sleeping five hours than one sleeping eight. Most exam-season eye complaints improve when the sleep improves.
What we would not spend money on: blue-light filter spectacles for children. The evidence that they reduce eye strain is weak. If your child already has a pair, there is no harm in it, but do not treat it as a substitute for an eye test.
If your child already wears glasses
Power changes fastest between ages 8 and 16. A prescription written 18 months ago may simply be wrong now, and studying through an outdated power creates exactly the strain you are trying to fix. Two practical points:
- Get the power rechecked every year, or sooner if the child starts moving closer to things again.
- If myopia is climbing by roughly 0.5 dioptre or more each year, ask specifically about myopia control options. There are spectacle lens designs, low-dose atropine drops and specialised contact lenses that can slow progression in suitable children. None of them reverse existing power, and not every child is a candidate, but the discussion is worth having early rather than at minus six.
Refractive surgery is not an option at this age. SILK, LASIK and similar procedures need a stable power for at least a year and are generally not done before 18.
When to get it checked
If the complaint is mild, follows long study sessions and clears with rest, try the changes above for two weeks. If nothing improves, or if any of the warning signs above are present, book a proper test — not just a vision check at an optical shop, but a paediatric assessment that includes cycloplegic refraction where indicated, an eye alignment check and a look at the back of the eye.
A full test takes under an hour, and drops used to relax focusing will blur near vision for a few hours afterwards, so plan it on a day without an exam. Our KPHB centre runs until 8:30 pm on weekdays, which usually means it can be done after school without missing classes.
