Is the vision screening device accurate?

Normally, babies who are 6 months old need to go to the hospital for a vision checkup, which uses professional vision screening equipment. The vision screening in a regular professional hospital is relatively accurate, usually they will test several times, and then take the average value as the reference value of our vision. If you get a vision check report and find that your vision level is seriously off the normal value, parents must pay attention to it, check it and treat it.
