Presbyopia is a normal physiological phenomenon. In this case, your eyes gradually lose their ability to focus on close objects. When the human eye is about 40 years old, the function of the ciliary muscle and lens begins to deteriorate, so the focus slows down. This is because the ciliary muscle function deteriorates. At this time, there is about 100 degrees of presbyopia, and then it increases by an average of ten degrees every year, about 200 degrees of presbyopia at the age of 50, about 300 degrees at the age of 60, and after the age of 60, the degree will not deepen significantly.
Common symptoms of presbyopia are:
- When you are reading a newspaper or a book, you have to look a little further away to see clearly
- When looking at distant objects and then at close objects, you feel that focus slows down
- Reading is easy to get tired and your eyes feel sore
- Difficulty reading small print
- Fatigue from tight work Brighter lights are needed when reading or working in close proximity
Although this is a disease that affects everyone in the natural aging process, it has recently been found that there is a trend towards rejuvenation, especially in recent years, the use of tablets and mobile phones has increased, causing the ciliary muscle to tighten for a long time, resulting in poor lens regulation. According to statistics, the average increase in presbyopia patients under the age of 40 is two to three percent, and the situation is worth paying attention to.
