Functional Vision and Quality of Life in a Modern Society - With Emphasis on Myopia and Cerebral Visual Impairment Among Youth

Society has become increasingly digital, and many everyday services have been replaced by digital self-service solutions. This puts greater demands on our vision and our ability to interpret what we see. At the same time, the number of children with nearsightedness (myopia) has increased rapidly. In some parts of Asia, as many as 60-70% of students in seventh grade are nearsighted, and a similar trend may develop in Europe. Nearsightedness is becoming a growing challenge in pediatric eye care. High myopia can lead to complications that require early detection and prevention. There are now several ways to slow down its progression, such as special contact lenses, glasses, and eye drops. However, the scientific evidence for these treatments varies, and there are currently no national or Nordic guidelines on how to use them. In addition, myopia may have a major impact on children's quality of life. Currently, there is no validated Swedish questionnaire that measures vision related quality of life across all age groups in children and adolescents. To address this, researchers in the United States developed the Pediatric Eye Questionnaire (PedEyeQ) in 2019. It is already available in English and Spanish and takes into account both the child's and the parent's perspectives on vision and daily life. The aim of this study is to translate, culturally adapt and test the PedEyeQ in Swedish children and adolescents, and to investigate how common refractive errors, especially nearsightedness - are today compared to 20-30 years ago. The study will include 300 healthy children and adolescents aged 0-17 years, divided into three age groups: 0-4 years, 5-11 years, and 12-17 years. Participants will be recruited through child health centers, preschools, and schools in the Örebro region. All participants will visit the eye clinic for a detailed eye examination, including: * Testing distance and near visual acuity * Measuring eye refraction (with and without eye drops that tempor
