Children rarely report blurred vision, because they have no baseline to compare it against. That is why screening intervals and a few parent-visible signs matter more in this age group than in any other.
Short sightedness in children is also the one area where the goal has shifted: slowing progression is now a recognised aim in its own right, separate from correcting the vision you have today.

When children should be tested, what the common findings mean, how short sightedness is now managed rather than simply corrected, and the signs that should prompt an appointment.
Children should be screened early, in the preschool years, and again during school. Development of the visual system is largely complete in early childhood, which is why some findings matter much more when they are picked up young.
If there is a family history of squint, lazy eye or glasses in childhood, or if the child was born prematurely, an earlier examination is usually advised.
How often a child needs an examination depends on their age and on what has been found before. A child with a normal examination and no risk factors is usually reviewed at longer intervals than one who wears glasses or has a family history.
A child should see an ophthalmologist when a squint or lazy eye is suspected, when vision does not improve as expected with glasses, after an eye injury, or when there is a family history of a significant childhood eye condition.
Yes, and earlier if anything is noticed. A child with reduced vision in one eye will rarely report it, because they have no comparison to make. Finding it before school matters because some conditions are more treatable while the visual system is still developing.
What this depends on
Whether there is a family history of squint, lazy eye or glasses in childhood
The signs worth acting on are squinting, sitting very close to a screen or book, holding things close, tilting the head, complaining of headaches after reading, or one eye turning.
Children rarely report blurred vision because they have nothing to compare it to. That is why parent-visible signs and screening intervals carry more weight in this age group than in any other.
Squinting can improve focus temporarily, which is why it can indicate an uncorrected refractive error, and it can also be a response to bright light or to discomfort. It is a reason for an examination rather than a diagnosis.
Headaches with close work in a child often occur with an uncorrected refractive error or with a focusing or alignment problem, since the eyes are working harder than they should.
Headaches are also commonly unrelated to vision, so an examination is what distinguishes the two rather than a pattern alone.
Sitting very close to a screen can simply be what children prefer, and it can also be a sign of short sightedness. It is worth an eye examination rather than management by moving the chair.
Lazy eye, or amblyopia, is reduced vision in an eye that is otherwise healthy, caused by the visual system not developing normally in early childhood. It is treated more effectively the earlier it is found.
This is the main reason screening in early childhood exists. Once the visual system has matured, the same treatment is much less effective.
A squint, or strabismus, is when the eyes do not point in the same direction. It can be constant or intermittent, and it can affect how vision develops in the misaligned eye.
A child with a newly noticed squint should be examined rather than monitored at home, and a squint that appears suddenly with double vision or other symptoms in an adult needs prompt assessment.
There is no fixed age at which contact lenses become suitable for children. The deciding factors are whether the child can handle the lenses and the hygiene routine reliably, and what the clinical reason for lenses is.
Some children are fitted with lenses for myopia management rather than for convenience, and in those cases the clinical rationale and the supervision are part of the plan.
Conjunctivitis in children is usually self-limiting or easily treated. It should be assessed if the eye is painful, if vision is affected, if the child is unwell with it, or if it is not settling.

Some sudden eye symptoms need urgent assessment
This answer explains what the symptom commonly indicates. If it has come on suddenly, or is
accompanied by pain or loss of vision, seek urgent care rather than waiting for an appointment.
A child needs urgent care for a chemical in the eye, an obvious injury, sudden loss of vision, sudden onset of a squint, severe pain, or a red eye with a contact lens in place.
Short sightedness in children results from the eye growing slightly too long for its focusing power, with both inherited tendency and environmental factors contributing.
The environmental part is the reason the advice for children includes outdoor time, and the reason progression is treated as something that can be influenced rather than simply watched.
Progression of short sightedness in children can be slowed, and options include specific spectacle lens designs, contact lens approaches and medication drops. Suitability and monitoring are clinical decisions.
The evidence base for these options is still developing, and different strategies suit different children. This is an area where the plan should be reviewed as the child grows rather than fixed at the start.
Screen time in children is associated with short sightedness in research, though the relationship is tangled with how much time is spent indoors and on near work generally rather than on screens alone.
What follows from that is a practical emphasis on outdoor time and breaks rather than on screen minutes as a fixed limit.
Time outdoors is consistently associated with less development and slower progression of short sightedness in children, and it is one of the few protective factors with a practical recommendation attached.
The mechanism is not fully settled, so the honest framing is that outdoor time is associated with better outcomes rather than proven to cause them. It is also a low-cost suggestion with other benefits, which is why it is made so often.
These answers describe what is generally true. They are not a diagnosis and they cannot say
whether a treatment is suitable for you, because suitability depends on measurements taken during
an examination. Only a qualified ophthalmologist who has examined you can decide.
