Presbyopic and nearsighted glasses have different principles, adapt to different groups, different application scenarios and other differences.
1, the principle is different: presbyopic lenses are mainly convex lenses, mainly will enlarge the object. Myopia glasses are concave lenses, which can reduce the distance of objects.
2, adapted to the crowd is different: presbyopia glasses suitable for ageing and refractive error occurs in the presbyopia crowd. Myopia glasses are suitable for myopic people, whose light can not be focused on the retina or whose image on the retina is not clear.
3, the application of different scenarios: presbyopia in most cases to be used in the observation of near text and objects. Myopia glasses usually need to be worn when looking at distant objects, and a small number of myopic patients may need to wear myopia glasses for long-term correction.
In addition to these differences, there are also differences in the refraction of light. If you need to wear glasses, it is recommended that you go to a hospital eye clinic in good time so that an optician can prescribe and fit the appropriate glasses.
