Astigmatism is a degree that can be converted into myopia. The calculation formula is: astigmatism degree /2= converted myopia degree. Astigmatism below 75 degrees can be achieved without contact lenses, and the vision is clearer. Generally speaking, after wearing contact lenses and putting on frame glasses, the eyes will feel dizzy for a moment, which is normal, because the magnification of contact lenses and frame glasses is different from that of eyes, so it needs to be adapted when changing. Some people are sensitive to astigmatism. If there is no astigmatism, contact lenses may be a little worse than frame lenses, so those with astigmatism can wear contact lenses, such as RGP (hard lens), which is quite healthy for the eyes and can achieve better vision, because it is stable in shape and small in size, which is conducive to the flow of tears, and can also produce the effect of tear mirror, making vision more perfect, but relatively more expensive.

In addition, all contact lenses have a set of nursing procedures, which must be strictly implemented, otherwise many complications can be blinding and irreversible, remember!
