Patients can measure their own vision through the vision chart, but the degree of myopia cannot be checked by themselves, so they can go to the hospital in time to have the degree of myopia tested by computerized optometry or other means.
Patients can check their eyesight by themselves through the visual acuity chart, and they can also go to the hospital for a visual acuity examination to clarify the level of their eyesight. Under standard illumination, the person to be examined stands at a distance of 5 meters from the vision chart and reads the characters on the chart to determine the person’s visual acuity.
Patients are unable to check the level of myopia on their own. If patients want to clarify the level of myopia, patients can visit the hospital in time to check the specific refractive error through computerized optometry.
It is recommended that patients with significant vision loss should seek medical attention in a timely manner to assess their condition and follow the doctor’s instructions for treatment.
