10 Vision Changes by Decade and the Screenings That Catch Them Early

2. The School Years (11-20) - Academic Vision Demands

The second decade of life brings new visual challenges as children transition into more demanding academic environments and begin to experience the first signs of myopia progression. During these school years, the visual system faces unprecedented demands from increased near work, including reading, writing, and computer use, which can contribute to the development and progression of nearsightedness. Research indicates that myopia rates have increased dramatically over the past several decades, with some studies showing that up to 50% of young adults in developed countries are now nearsighted, compared to just 25% in the 1970s. This increase is largely attributed to lifestyle changes, including more time spent indoors, increased screen time, and reduced outdoor activities. The teenage years also mark the period when many individuals first become candidates for contact lenses or refractive surgery, making comprehensive eye care even more important. During this decade, eye screenings should focus on monitoring refractive error progression, assessing eye coordination and focusing abilities, and evaluating overall eye health. Annual comprehensive eye exams are recommended throughout the school years, with more frequent monitoring for children who show signs of rapidly progressing myopia. Early intervention strategies, including specialized contact lenses, atropine drops, or increased outdoor time, can help slow myopia progression and reduce the risk of high myopia and its associated complications later in life.
