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.
The "struggle to survive", "survival of the fittest" and "natural selection" are all phrases to indicate the main guiding mechanism of evolution: differential reproductive success.
Adaptation refers to specific traits that help an organism survive in its environment, while evolution is the process by which populations of organisms change over generations. Adaptation is one mechanism through which evolution occurs, as individuals with beneficial adaptations are more likely to survive and reproduce, passing on those traits to their offspring.
In the science, evolution means change over time. These changes are selected by the environment. What genes (traits) that will allow a species to survive will be passed on to the next generations.
Success in terms of evolution by natural selection is typically measured by an organism's ability to survive and reproduce in its environment. Traits that enhance an organism's chances of survival and reproduction are favored by natural selection, leading to their increased frequency in a population over generations. Ultimately, success in evolution is defined by passing on genetic material to future generations.
Natural selection is a key mechanism in evolution where organisms with advantageous traits are more likely to survive and reproduce, passing on those traits to future generations. This process leads to the gradual change and adaptation of species over time.
Evolution and adaption to survive. (legs to run, eyesight to spot predators)
New generations are better suited to survive than previous generations.
Onset of symptoms is later in life, after people have already had children.
pronghorn antelope survive by its speed and keen eyesight to get away from their predators
The ancestors of the hamster did not need a tail to survive, and thus over generations, evolution and natural selection did its thing and now hamsters have only a stub of a tail.

It helps them survive because they can see when predators are coming and run away

Bald eagles survive by hunting and fishing. They are very good at both of these practices. Their eyesight is remarkable being able to see things with about a 2000 percent more telescopic eyesight than humans.
