Well, they are different from each other. First, when you get myopia, it will be hard for you to read at a close distance, even if you are very young. And the myopia can develop at 20 years old. Also, it is a leading cause of blindness. By the way, according to some research, the degree of myopia have be related to degenerative eye conditions and diseases like glaucoma and cataract , which can affect both vision and ocular health. On the other hand, presbyopia is a condition, which is caused by aging. When you get this kind of disease, you will find it difficult to read small words at close distances or to work on the computer for long periods of time. So in some degree, it can be annoying. And you can just prevent it by using lutein.
Generally speaking, they are both eye problems, and could affect our vision to some extent. However, they are resulted from different causes and different parts of the eyes. Myopia would make distant things obselete while presbyopia would make it hard for you to see close things clearly. Anyway, once got them, try to take measures.
There exists the big difference between myopia and presbyopia. The myopia is referred to the one that can't see clearly at the far things. However, the presbyopia refers to the one who can't see clearly at the near things. These two eyes problems are totally different. Myopia is the eye looks that can not be seen the far content but see nearly content. This symptom is in the refractive static premise. The distant objects are not in the retina convergence and in the retina formed before the focus which will cause the visual deformation. It will lead to a distant object vague .Myopia is always happened in the after period environment which is caused by the not good habit of using eyes. However, the presbyopia is happened with the growing age. When you grow old, your eyes structure will be changed to some degree which will cause the blurry vision at the near thing. The myopia could be treated through the lasik surgery. And the presbyopia could not be treated but could be corrected by the special glasses.
