Presbyopia and astigmatism are two different refractive states, and if both conditions exist in the eye, they need to be treated separately. Because presbyopia is due to the decrease in the adjustment ability of the lens after ageing, the adjustment ability of the eyes is also decreasing, and there is a decrease in near vision. Generally, it is difficult to read at close range, and when reading, you like to put the target far away and feel that you can see more clearly and comfortably. The correction of presbyopia can be done by wearing presbyopia glasses to improve the near vision. Astigmatism is caused by irregularities in the shape of the cornea, which leads to a decrease in distance vision and blurriness when looking into the distance. Astigmatism can be corrected by wearing frames, corneal contact lenses or refractive surgery to improve distance vision.
