Pay attention to fit. Anything too big or too heavy can slide down and leave the child looking through the wrong part of the lens. Kids’ heads are shaped differently from adults’, and a good optician will make sure the glasses fit at three crucial points: the widest part of the face (it should match the width of the glasses), along the nose (a child’s nose bridge is flatter than an adult’s, and uneven weight distribution can affect nose development) and behind the ears (the frames should point straight back and wrap gently around the ear without pressing into the head). Now they can focus on fun.
