It is called: forty is not confused, fifty know the destiny.
But as long as you maintain a young mindset and an active and healthy life, even if you reach the age of 40-50, you can still play in life and in the workplace.
However, there are also some phenomena that always reveal the secret of age, such as unconsciously setting the self-mention to the big one, holding the mobile phone farther away to see, and not being able to read some words in a slightly darker place.
Sorry, this could be.... Presbyopia performance.
How do good eyes start to "flower"?
Presbyopia, medically known as presbyopia, is essentially a decline in the physiological regulatory function of the eye.
Just like a camera, as the adjustment function of the camera decreases, the resolution of the things taken in the photo decreases and gradually blurs.
What are the reasons for the bad eyes of middle-aged and elderly people?
First, disease factors
For the middle-aged and elderly people, the main reason for the bad eyesight is related to some diseases. For example, when suffering from senile macular degeneration, or cataracts, it is easy to have bad eyes.
In addition, if you have some eye inflammation, such as retinitis or keratitis, it will also cause the patient to have decreased vision and blurred vision.
Second, the use of eyes is improper
If you turn off the lights for a long time to watch TV, or read a book in a poorly lit environment, it will lead to a rapid decline in the eyesight of the middle-aged and elderly people.
In addition, many middle-aged and elderly people will not pay attention to eye hygiene, such as the behavior of rubbing the eyes with their hands for a long time, which will lead to some inflammation in the eye area, resulting in a rapid decrease in vision.
Third, the age factor
As we age, the functions of the human body are constantly degraded. In particular, the function of the eye will continue to decline, which can easily cause the middle-aged and elderly population to have decreased vision or blurred vision.
All in all, for the middle-aged and elderly people, if the behavior of turning off the lights and looking at the mobile phone for a long time will cause the above three very obvious harms to the eyes, and will also affect the sleep and brain health of the middle-aged and elderly people.
In addition, the above three factors are also the main reasons for the loss of vision in the middle-aged and elderly population.
For the middle-aged and elderly people who have bad eyes, we must correct some bad living habits. If it is caused by disease factors, it is necessary to quickly go to a regular hospital for treatment and treatment in order to maximize the protection of eye health.
Once presbyopia appears, the most important thing is to ---- correction
Presbyopia can compensate for the lack of adjustment by wearing convex lenses, and determine whether the original refractive state is myopia, farsightedness or orthopedic by wearing a convex lens, and then determine the degree of aging.
After that, I feel the ability to adjust the residual adjustment, adjust the degree in time, and choose the right lens, you can choose the right reading glasses for yourself.
In addition to wearing reading glasses, you can also adjust the environment, improve brightness, adjust the font size and color of the reading, and at the same time, you need to rest properly when using the eyes to avoid using the eyes for a long time.
Myopia, do I still need to wear reading glasses?
In fact, myopic eyes still need to wear glasses when looking far, and may not need to wear glasses when looking close.
This is due to the fact that myopia is imaged in front of the retina, while presbyopia is imaged behind the retina when near. If the degree of myopia and presbyopia are similar, the imaging is right on the retina.
If the degree of both is not high, the degree of myopia is low, and the degree of presbyopia is high, then it is necessary to wear a convex lens; if the degree of myopia is higher and the degree of presbyopia is low, then it is necessary to lightly match the degree of myopia when looking close.
Of course, there are also some people who are not as good as wearing glasses, and presbyopia correction surgery is currently a hot spot in the field of refractive surgery, and this technology has gradually matured.
However, surgery is surgery after all, and even mature surgery cannot be 100% confirmed to be safe.
