The vision of 200 degrees of myopia is around 0.4-0.5. Some people are very compensated and may also see around 0.7, while others are poorly compensated and cannot even see 0.1. Regardless of the degree of myopia, it depends on the age and your needs. In children, even 200 degrees of myopia, although the degree of myopia is not high, but also need to wear glasses, without glasses will cause unhealthy visual development, but also may deepen the myopia of the situation. If among adults, there are more options available. If the daily use of cell phones and computers at close range is the main concern, it may be possible to meet the daily vision needs without glasses. If you are in a special profession, such as a driver or a long-distance vision profession, you may need to wear a pair of glasses to ensure that your daily vision is clear.
