What is presbyopia?

Presbyopia is a normal physiological phenomenon where refractive errors occur due to aging. As age increases, the lens gradually hardens, its elasticity decreases, and the function of the ciliary muscle also gradually decreases, leading to a decrease in eye regulation function.

Although different from pathological refractive errors, presbyopia patients have decreased binocular adjustment function, usually manifested as inadequate adaptation to close range work. Therefore, it is necessary to choose to wear corrective glasses or undergo surgical intervention based on personal life or work needs for visual accuracy.

What is the incidence of presbyopia in the population?

Presbyopia is a physiological phenomenon that generally begins to appear between the ages of 40 and 45.
The appearance of presbyopia is related to age, which means that with age, anyone will experience presbyopia. Excluding age factors, the development of presbyopia is also related to eye usage, personal physical fitness, and the use of certain medications. Even if the age and refractive status of the eyes are the same, the timing of the onset of presbyopia symptoms varies due to different working distances. For example, people who are accustomed to working close to the clock repairman and sculptor often experience presbyopia symptoms earlier.

What are the causes of presbyopia?

When we image objects with our eyes, light passes through the cornea and lens to form images. The cornea is transparent so that light can smoothly enter the eye. The lens is equivalent to the lens of a camera, and as the lens is stretched and shortened, objects in the distance and near can be clearly seen.
However, as the eyes age, the elasticity of the crystalline lens weakens, meaning that the camera lens cannot freely retract and retract, resulting in the object being "out of focus" and unable to see clearly.

Symptom

The general symptoms of presbyopia include difficulty in seeing up close and not lasting, the need for stronger lighting while reading, and the symptoms becoming more severe with age.
Some middle-aged and elderly people may experience symptoms of visual fatigue such as eye swelling, tearing, and headache, especially when using their eyes excessively.

Prevent

Presbyopia is a manifestation of aging and a normal physiological change that cannot be prevented at present. However, establishing good lifestyle habits can help delay the onset of presbyopia. Here are some suggestions:
● Pay attention to rest, live a regular life, ensure sufficient sleep, and avoid staying up late;
● Avoid prolonged eye contact and reduce the time spent reading books or electronic screens up close;
● When using your eyes excessively, pay attention to resting or looking far away with your eyes closed. You can use a warm towel to apply to your eyes and do eye exercises frequently to relieve eye fatigue;
● Wear sunglasses with UV radiation protection when engaging in outdoor activities or staying in sunlight for extended periods of time;

● Regularly check vision;

● Eat more carrots, animal liver, blueberries, black sesame, and other foods that contain high levels of antioxidants and vitamin A β- Food containing carotenoids.
