Most children with low vision retain useful, trainable sight. A clinical AbilityScore and any diagnosis are formed only at a Pinnacle centre.","answer_md":"*When the world looks blurry, faded or narrow, every child experiences it differently — and naming that difference is the first step to support.*\n\n## In short\nVisual impairment is described in two useful ways: by **how much a child can see** (the levels) and by **what part of seeing is affected** (the types). The recognised levels run along a spectrum — mild, moderate, severe and profound vision loss, through to blindness — based largely on how clearly a child sees and how much of the visual field they have. The types describe whether the difficulty lies in sharpness, field of view, eye-brain processing, or eye structure. Almost every child with low vision still has *useful sight* that can be built upon.\n\n## The levels of visual impairment\nGlobal frameworks (WHO ICD-11) group vision loss by severity, measured through clear sight (visual acuity) and field of vision:\n\n- **Mild vision impairment** — small reductions in sharpness; often supported well with glasses.\n- **Moderate vision impairment** — noticeable difficulty seeing detail at distance or near.\n- **Severe vision impairment** — significant loss; daily tasks need adaptation and support.\n- **Blindness** — little or no usable sight, including profound loss of the visual field.\n\nIn children we also speak of **low vision** — reduced sight that glasses or surgery cannot fully correct, but where the remaining vision is precious and trainable.\n\n## The types of visual impairment\n- **Refractive** — blurriness from the eye's focusing (short-sight, long-sight, astigmatism), often correctable with spectacles.\n- **Visual field loss** — a narrowed or patchy field, so a child may miss things to the side, above or below.\n- **Cortical / cerebral visual impairment (CVI)** — the eyes work, but the brain processes images differently; a common cause in children.\n- **Structural / ocular** — affecting parts of the eye itself (cornea, lens, retina, optic nerve).\n- **Functional vision differences** — how a child *uses* their sight for play, reaching, reading and moving about.\n\n## The Pinnacle way\nA clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from an online description or a single observation at home. Our teams map your child's *functional vision* — how they use what they see — and build a plan that grows their independence. Start with [understanding visual impairment](/visual-impairment), explore [occupational therapy](/occupational-therapy) for daily-living and sensory support, and learn how [the AbilityScore works](/ask/what-is-the-abilityscore-and-how-is-it-calculated).\n\n## Trusted sources\nWorld Health Organization classification of vision impairment (ICD-11); WHO guidance on eye health and childhood vision; American Academy of Pediatrics guidance on children's vision and development.\n\n**Next step —** Noticed your child squinting, holding things very close, or missing objects to the side? [Book a developmental and vision screen with a Pinnacle clinician](/visual-impairment).\n\nThis is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.","canonical":"https://pinnacleblooms.org/ask/what-are-the-types-or-levels-of-visual-impairment","editorial":{"reviewed_at":"2026-06-11T20:12:18.613642+00:00","reviewed_by":null,"developed_by":"SETU Consortium · Pinnacle Blooms Network"},"alternates":[{"href":"https://pinnacleblooms.org/ask/what-are-the-types-or-levels-of-visual-impairment","lang":"en","indexable":true},{"href":"https://pinnacleblooms.org/ask/what-are-the-types-or-levels-of-visual-impairment-te","lang":"te","indexable":true}],"dimensions":[{"key":"conditions","label":"Conditions"}],"meta_title":"Types & Levels of Visual Impairment","meta_robots":"index, follow, max-image-preview:large","everyday_tip":"Use high contrast and good lighting at home — dark toys on a light tray, bold-outlined books — and name what you see together.
