I’m in my early 40s, and I’m having trouble seeing up close.
What’s happening to your eyes is perfectly normal, and is called Presbyopia. When we are young, the crystalline lens inside our eyes can change shape easily, allowing us to focus up close. As we get older the lens loses its flexibility, and it becomes harder for us to focus on near objects. Our focusing ability peaks around age 10 or 11, and slowly decreases as we get older. Around the age of 40, many people start to experience difficulty at near. These people usually begin to hold reading material at arm’s length in order to see it. This is often the first sign that presbyopia has begun.
