The signs to watch are the same for every child. Only a Pinnacle clinician can confirm what's happening.","answer_md":"*If you've noticed your son squinting, tilting his head or sitting too close to the screen, that worry is worth listening to — let's make sense of it together.*\n\n## In short\nThere is **no major difference in how boys versus girls experience [visual impairment](/) itself** — the eye and the way vision develops are the same. What can differ is how a *child* shows it: some children, regardless of sex, mask difficulty by sitting closer, avoiding fiddly tasks, or getting frustrated. A few specific inherited conditions (such as red-green colour vision difference and some retinal conditions carried on the X chromosome) are simply more common in boys. So the honest answer is: the impairment is the same — the clues just need careful watching in every child.\n\n## What to watch in your son\nThese everyday signs deserve a gentle eye check, whether your child is a boy or a girl:\n\n- **Sitting very close** to the television, book or tablet\n- **Squinting, tilting the head, or covering one eye** to focus\n- **Eyes that wander, cross or don't move together**\n- **Bumping into things**, clumsiness, or hesitating on stairs and kerbs\n- **Rubbing the eyes a lot**, watering, or complaining of headaches\n- **Trouble with colours** — mixing up reds and greens (more common in boys, often inherited)\n- **Losing place when reading** or avoiding close-up tasks\n\nA single moment isn't a diagnosis. A *pattern* across days is the real flag.\n\n## The science, briefly\nThe WHO classifies visual impairment under **ICD-11 9D90**, graded by how clearly a child sees. While the condition affects boys and girls equally overall, some causes are sex-linked: colour vision difference affects roughly 1 in 12 boys versus far fewer girls, and a handful of retinal conditions are inherited on the X chromosome, so boys show them more often. Early detection matters enormously — the young visual system is still developing, and timely support protects learning, movement and confidence.\n\n## The Pinnacle way\nA clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from an online form or a list of signs.
