How did bad eyesight survive evolution and continue to be passed down through generations?

Bad eyesight, or myopia, may have persisted in evolution due to a combination of genetic and environmental factors. Genetic mutations that cause myopia may have provided some advantages in certain environments, such as improved nearsighted vision for tasks like hunting or gathering. Additionally, modern lifestyles that involve extensive use of screens and limited exposure to natural light may contribute to the prevalence of myopia in populations today. As a result, individuals with myopia may continue to pass down these genetic traits to their offspring, leading to the persistence of bad eyesight through generations.
