Vision is the sense that develops most slowly after birth. A newborn can see approximately 20 to 30 centimetres — the distance to a caregiver's face during feeding — but little beyond that. Over the first year, visual acuity, colour vision, depth perception, and eye coordination develop rapidly. Supporting this development and catching problems early makes a significant difference.
Normal Eye Development Milestones
At birth: can see faces at close range, responds to bright light. By 2 months: begins following moving objects with eyes, starts making eye contact. By 4 months: can follow moving objects at a distance, beginning depth perception, starts reaching for objects they see. By 6 months: eye colour usually established, vision approaching adult acuity. By 9 months: good depth perception, can track fast-moving objects. By 12 months: vision nearly adult quality, can recognise familiar faces at a distance.
Common Eye Problems in Indian Babies
Sticky eye (neonatal conjunctivitis) — yellow or green discharge from the eye with crusting, common in newborns. Often caused by a blocked nasolacrimal duct (tear duct) rather than infection. Clean with cotton wool soaked in cooled boiled water, wiping from inner to outer corner. Gently massage the inner corner of the eye daily — this often resolves a blocked tear duct. See your doctor if discharge is heavy, eyes are red and swollen, or does not resolve by 12 months.
Squint (strabismus) — one or both eyes turning inward or outward. In the first 3 months, intermittent squinting is normal as the eyes learn to work together. After 3 months, any constant squinting should be evaluated by a paediatric ophthalmologist. Untreated squint can lead to amblyopia (lazy eye) where the brain suppresses vision in one eye.
Amblyopia (lazy eye) — reduced vision in one eye because the brain prefers the other. Often caused by squint or a significant difference in prescription between the two eyes. Early detection (before age 7 when visual pathways are still developing) is essential for effective treatment.
The Kajal Tradition
Applying kajal (kohl) to babies' eyes is a widespread tradition in India. Traditional kajal made with home-burned oil is different from commercial kajal which can contain lead and other metals. No kajal should be applied directly to a baby's eye — this risks infection and toxicity. If using kajal for cultural reasons, apply outside the eye area only, never inside the lid.
First Eye Examination
The Indian Academy of Pediatrics recommends a paediatric eye examination at 6 months. Many paediatricians perform a basic red reflex check at well-child visits — the red reflex should be present in both eyes in a photograph taken with flash. Absence of red reflex in one or both eyes requires immediate ophthalmology referral to rule out retinoblastoma (eye cancer).
