1. What is presbyopia?

In the hard "working" life day after day, we are gradually entering middle age. While our ability, responsibility and money are "growing day by day", our eyes begin to "lag behind". You seem to be a little tired and fuzzy when looking close.

In fact, this is a physiological phenomenon caused by the "parts" in your eyes announcing the "strike". It is mainly manifested in the poor elasticity of the lens, the weak contraction ability of the ciliary muscle, and the inability to adjust normally when looking at the near place, resulting in the light converging behind the retina and unable to see the near place. It is also called presbyopia in medicine.

2. People with myopia will not get presbyopia?

Unfortunately, not. Although myopic people have presbyopia late, when myopic eyes look at nearby objects, the diopter of the lens does not need to be adjusted as much as normal people. Therefore, when the adjustment ability of the lens decreases, the reaction of myopic people is slower than that of non myopic people.

However, as the lens continues to age and harden, people with myopia will eventually be unable to see clearly near. Myopia is the refractive state of the eye, and presbyopia is the adjustment ability of the eye. The essence of the two is not the same thing. When these two situations occur at the same time, myopic people will not be able to see both near and far.

3. Can presbyopia offset myopia?

Assuming that the degree of myopia and presbyopia are just equal, the short-term "offset" can really make you happy for a while. The feeling that you don't need to wear glasses near makes you particularly satisfied, but you still need to wear myopia glasses at a distance. Moreover, the short-lived "offset" will soon slip away with the continuous aging of the lens, and you will still face the situation that you can't see far and near.

In addition, it is impossible for patients with myopia to completely offset the "300 degree" of presbyopia, even if the "300 degree" of myopia can not be completely offset.
