(1) Background: Visual acuity (VA) is essential for children's quality of life, and its relationship with socioeconomic status (SES) highlights disparities in healthcare. This study investigated the influence of SES on changes in schoolchildren's VA over one year. (2) Methods: Initial examinations were conducted on 1822 children (8-10 years).

Hence, the precision and agreement of commercially available biometers is of vital interest to understand their variability and interchangeability in the paediatric population.
Background: Different biometers are available to measure axial length and monitor myopia progression in clinical practice.
Background: The objective of this study is to assess the prevalence of visual impairment and visual care practices and its association with socioeconomic conditions in the infant population in Catalonia.
Methods: The Catalan Institute of Statistics provided a random sample of 0 to 14-year-old non-institutionalized children whose parents were interviewed in a continuous health survey from 2011 to 2015 in Catalonia. A multistage stratified and random sampling procedure considering age, sex, county and town was followed.
Background: In high-income countries, the prevalence of blindness and visual impairment is higher among women, regardless of age although the mechanisms that produce these gender inequalities are not well understood. The objectives of this study were to analyse gender inequalities in the prevalence of blindness and visual impairment, age of onset, diagnosed and undiagnosed status and related eye diseases among visually impaired individuals.
Methods: Data were obtained from the 2008 Spanish Survey on 'Disability, Personal Autonomy and Dependency Situations' (n = 213 626) participants 360 blind (160 men and 200 women), and 5560 with some visual impairment (2025 men and 3535 women).
Objective: To examine the prevalence of blindness, visual impairment, and related eye diseases and conditions among adults in El Salvador, and to explore socioeconomic inequalities in their prevalence by education level and occupational status, stratified by sex.
Methods: Based upon the Rapid Assessment of Avoidable Blindness (RAAB) methodology, this nationwide sample comprised 3 800 participants (3 399 examined) ≥ 50 years old from 76 randomly selected clusters of 50 persons each. The prevalence of blindness, visual impairment and related eye diseases and conditions, including uncorrected refractive error (URE), was calculated for categories of education level and occupational status.
