When it comes to the symptoms of farsightedness, people naturally associate it with myopia, which they know and understand more accurately than farsightedness. There are similarities and differences between myopia and hyperopia, but the similarities are that both are refractive errors that cause blurred vision. The similarity is that both are refractive errors and both cause blurred vision. The blurred vision is subdivided into blurred vision and blurred vision, and the difference between the two is that the blurred vision is different. We all know that the symptom of myopia is definitely blurred vision in the distance and clear vision in the near, so we must think that farsightedness is the opposite of myopia: you can see clearly in the distance but not in the near. It would be a big mistake to understand farsightedness literally, and not to think of it in terms of its name. The symptoms of farsightedness are relatively more complicated than myopia: for mild farsightedness within 40 years of age, because the adjustment ability of this age group is still relatively good, the majority of the adjustment ability is higher than the farsightedness, so the eye can use the adjustment after the image in the retina to move forward to the retina, so seeing far and near are not a problem, such as the adjustment ability is slightly poor, in the near will appear visual fatigue. For medium and high farsightedness, the adjustment ability of the human eye is lower than the degree of farsightedness, and it is not clear to see far and near, so you need to wear a certain degree of convex lens to see things more clearly and comfortably. 40 years of age or older, because the adjustment ability of the human eye has become worse, so even mild farsightedness will appear to see far and near difficulties, especially in the near will be more obvious, so people with farsightedness wear glasses earlier than those with orthopia and myopia. People with hyperopia wear glasses earlier than those with orthopia and myopia. So the two main symptoms of farsightedness are: blurred vision (distance or near vision) and eye strain. When one or both of these symptoms occur, the eyes are telling people that it is time to wear glasses.
