Can astigmatism wear contact lens? sure

First: Ophthalmologists said that astigmatism can wear contact lenses, and regular astigmatism can be corrected by using frame astigmatism glasses or astigmatism contact lenses. Irregular astigmatism can only be corrected with high oxygen permeable hard contact lenses, and the usual maintenance measures should be paid attention to.

Second: the biggest advantage of contact lens to correct astigmatism is stability and no aberration. If the frame lens is worn for a long time, the relative position between the frame and the eyes is easy to change, which will cause the deviation of astigmatism axis correction, and cause eye discomfort and vision loss.

Third: after wearing concealed glasses, because the lens and cornea have the effect of tears (this effect is often called tear lens effect), it can correct part of astigmatism. The astigmatism below-1.50dc can be corrected for water-containing contact lenses. If the astigmatism is greater than - 1.50dc, astigmatism stealth glasses are needed

matters needing attention

Contact lenses are widely used to correct ametropia. They are about the same size as buttons. They are very thin and transparent. It is divided into soft mirror and hard mirror. The soft lens is made of hydroxyethyl methacrylate, which is soft and can absorb water. It is soft and comfortable to wear, but it is easy to deform and damage, so it is not suitable for astigmatism; the hard lens is made of methyl methacrylate, which is hard and not easy to deform, so it is suitable for correcting high astigmatism and keratoconus.
