A child's eyes are not a smaller, static version of an adult's eyes. The eye grows, the brain learns to process visual information, and the cooperation between the two eyes gradually develops.
Infancy
In the first few months, the infant learns to focus, follow faces and objects, and coordinate their eyes. Occasional instability may appear very early, but frequent deviation after the first few months requires evaluation.
Preschool Age
Visual acuity, depth perception, and hand-eye coordination develop. A child may have a problem without complaining because they don't know what clear vision is like. That's why preventative check-ups are important.
School Age
Demands for distant and near vision increase. Myopia may appear or progress as the eye grows, especially during school ages. Blurry vision at the board, squinting, very close distance to a book, or headaches are reasons for an examination.
Adolescence
The prescription may continue to change. Glasses need regular checks for both optical correction and fit, because the face also changes.
Why the frame size changes
As the nose, face width, and ear distance grow, the bridge, lens width, and temple length that fit properly change. We do not buy an excessively large frame "to last".
