The degree of myopia often cannot be measured by oneself, and needs to be judged through the professional optometry process, which includes the initial, precise and confirmation stages.
1. Initial stage: The type and degree of refraction is initially obtained through the screening optometry and computerized optometry; corneal astigmatism is obtained through the corneal curvature meter examination.
2. Precision stage: use comprehensive optometry to determine the refractive information and obtain the prescription for the best visual acuity, i.e. myopia.
3. Confirmation stage: Personalized adjustments and evaluations, such as trial frame testing, are performed to obtain the final vision prescription, which confirms the degree of myopia.
In addition, myopia requires visual acuity testing and fundus examination to rule out other eye disorders. It is recommended to consult a doctor for the measurement of the degree of myopia in time.
