By 12-16 weeks infants’ eyesight allows them to see clearly and from further away. Over the following year, infants’ eye body/hand coordination improves with long distance judgement becoming more accurate. Usually eye problems tend to present between 18 months and 4 years of age. While a variety of different problems and conditions may occur, two are common: a crossed or wandering eye and one eye focuses differently to the other (for example one eye is more farsighted than the other). School aged children frequently have vision problems which include focus and alignment disorders (like refractive errors, amblyopia-“lazy eye”, and strabismus) and eye diseases (like conjunctivitis, cataracts, and color blindness).
