As your child grows and develops, the depth of the vision screenings will become more in-depth and check for different abnormalities. For example, a pediatric vision exam for an infant will involve tests of pupil response to light, their ability to fixate on an object and follow it with their eyes, and other similar exams. As they get older, they will be tested with retinoscopy, which examines the retina, random dot stereopsis to see how well your eyes work together, and a visual acuity test, in which they will also be asked to read letters or numbers of various sizes on a chart at a specific distance to observe how far they can see. These tests can help identify issues such as nearsightedness, farsightedness, astigmatism, strabismus, a misalignment of the eyes, color blindness, problems with depth perception, and more.
