What is the best possible vision rating in terms of decimal notation?

The best vision is generally 5.3 and 2.0. Currently, there are two main methods to record vision. If the 5-point system is used, the best vision is 5.3. If the decimal system is used, the best vision is 2.0. We should pay attention to protecting our vision in daily life, avoiding reading for too long or using electronic products such as mobile phones and computers for extended periods. If pseudomyopia occurs, it is necessary to adjust and recover promptly to prevent it from turning into true myopia. There are two main methods to record vision: the 5-point system and the decimal system. The ideal vision in the 5-point system is 5.3, while the ideal vision in the decimal system is 2.0. Unaided vision reaching 5.0 or above in the 5-point system, or 1.0 or above in the decimal system, is considered normal.

1. Learn scientific eye-using methods. Take regular breaks while reading or using electronic products to avoid eye fatigue. Practice eye exercises regularly.

2. If vision declines, consult an ophthalmologist promptly. Perform a pupil dilation test to determine whether it is true myopia or pseudomyopia.

3. If pseudomyopia occurs, there is a possibility of recovery. Do not rush to get glasses. Under the guidance of a doctor, corrective methods can be used to restore normal vision.
