summary

With the increase of age, the lens gradually hardens, the elasticity weakens, and the ciliary muscle contractility decreases, which leads to the decrease of accommodation, and the near point moves far away, resulting in the difficulty of close vision.

What's going on in advance

First: some people have "hyperopia" when they are young, usually around 150 degrees. After 30 years old, people's eyesight increases by 10 degrees every year. The eye's ability to adjust and compensate is generally within 150 degrees. If it exceeds this degree, it will be difficult to adjust and compensate.

Second, it is related to people's overuse of eyes, lack of rest and sleep, and excessive mental stress. Presbyopia symptoms appear sooner or later or severity, in addition to the original refractive state, and everyone's work nature and learning habits have a great relationship.

Third, "young presbyopia" people are mainly concentrated in the white-collar class. Due to the increasingly fierce social competition, their spirit is in a state of stress all day long, and their body is in a state of sub-health. Most of these people deal with computers, and their eyes stare at the computer screen for a long time. Coupled with lack of sleep, their eyes can not get enough rest, which leads to overwork and presbyopia "report" in advance.
