In fact, in my opinion, the eyesight will not get worse with the age. Because I am a girl whose eyesight did not get worse, and now I am 40 years old. If you found that your eyesight is getting worse, I think the main reason is not your age, instead, you did not protect your eyes properly. Like me, I remember that I became nearsighted when I 15 years old, at the same time, I found I am not so beautiful with glasses as without glasses, so I decide to get rid of them. From that day on, I take care of my eyes just like taking care of myself, for instance, making them have a rest when they are tired and giving some eye drops to them when they are dry. Now I can look distance without glasses clearly although I am 40 years old. As a matter of fact, when you found your eyes are not so good as before, I think you should find the reasons from yourself instead of the objective reasons. Hope you can think twice.
