If Junior sees those Backyardigans stickers, he’ll be demanding glasses of his own to be like Pablo! I wonder if they make “Groucho Glasses” is size 24M…..

Julie, babies who are in glasses at age 12 weeks, almost always were born with cataracts. Those are often caught by the doctor at their first pediatrician visit. For older pre-verbal kids, they usually use preferential looking tests: a series of rectangular grey cards that have a smaller square of black and white stripes. A baby (and really anyone) will look at the black and white square, because it’s more interesting than the grey background. The series of cards has a square with decreasing sized stripes until it is impossible for someone even with good vision to differential between the square and the background. They show the cards until the baby stops noticing the square, and that gives an approximation of their visual acuity. The eye doctor will also dilate the eyes and use a retinoscope to look at the retina to see it’s shape which gives an indication of if the baby is nearsighted or farsighted, and to what degree. That was probably way more than you wanted to know.
