Can I wear contact lenses if I have astigmatism

Many nearsighted girls prefer to wear contact lenses rather than glasses. Contact lenses look better than ordinary glasses, and they also make the glasses appear larger than usual. However, some girls are not only nearsighted, but also have astigmatism. The main manifestation of astigmatism is double vision. When fitting glasses, they often need to add astigmatism lenses. So, can you wear contact lenses if you have astigmatism?

Contact lenses are divided into two types: ordinary contact lenses and astigmatism contact lenses. Ordinary contact lenses are used by people with myopia, while astigmatism contact lenses are worn by people with astigmatism. Generally speaking, astigmatism contact lenses are more expensive than ordinary ones and have fewer choices. Therefore, many people are unwilling to wear astigmatism contact lenses even if they have astigmatism.

Do I have to wear astigmatism contact lenses if I have astigmatism? Professionals say that this depends on the specific degree. If the astigmatism is less than 100 degrees, or to be precise, less than 75 degrees, then you don't need to wear astigmatism contact lenses. You can add half of the astigmatism degree to the frame glasses, and then convert it into the degree of ordinary contact lenses. This can also ensure normal vision. If the astigmatism degree exceeds 100, you will need to prepare astigmatism contact lenses to better correct your vision.

In life, some people experience eye fatigue, poor night vision, decreased vision, headaches from reading for a long time, etc. when wearing contact lenses. This is not only because of unhealthy eye use, but may also be caused by improper correction of astigmatism.

If the astigmatism exceeds 100 degrees, continuing to wear ordinary contact lenses will not only fail to achieve the correct vision requirements, but will also make the eyes easily fatigued, causing troubles in life and study. Therefore, it is necessary to correctly correct the astigmatism.

Currently, contact lenses are widely used to correct refractive errors. They are about the size of a button, very thin and completely transparent. It is divided into soft lens and hard lens. Soft lenses are made of hydroxyethyl methacrylate, which is soft, can absorb moisture, and are soft and comfortable to wear, but are easily deformed and broken, and are not suitable for astigmatism; hard lenses are made of methyl methacrylate, which is hard and not easy to deform, and are suitable for correcting high astigmatism and keratoconus. .
