Problems solved by technology
[0002] In existing ophthalmology examinations, it is necessary to carry out visual acuity examination on a single spectacles. Generally, a visual acuity chart is used. A person stands at a certain distance from the visual acuity chart, and then shields the other eye with his or her hand. When covering one eye, the tester may use the covered glasses to look at the vision chart through the gap in the hand, resulting in inaccurate test results
When holding the mask to cover one eye, if the time is too long, the hands will feel sore, especially in pediatric examinations, children are reluctant to lift the mask, and they will cry easily after a long time
