Presbyopia is an age-related condition that affects the ability to focus on near objects. It typically begins to develop in people in their 40s and continues to progress as they get older. There are a number of factors that can affect how quickly presbyopia progresses, including the health of the eyes and the overall health of the individual. Typically, presbyopia progresses slowly and steadily over time. However, it is recommended to see a doctor as soon as you start noticing symptoms of presbyopia so that a treatment plan can be provided to prevent the condition from deteriorating further.
