Eye problems in children can have a major impact on their development. Common conditions include cataracts, trachoma, refractive errors, and retinopathy of prematurity. Nutritional deficiencies like vitamin A can also damage children's eyes, potentially leading to corneal ulceration, scarring, or perforation. Signs of eye problems in children include constant rubbing, redness, tearing, abnormal eye alignment or movement, light sensitivity, poor focusing, or difficulty seeing objects close or far away. Regular eye exams are important to detect issues early and prevent vision loss or other impacts on children's overall health and growth.
