A child fails the hyperopia test if they correctly identify how many symbols in either eye?

  1. 2 or more

  2. 3 or more

  3. 4 or more

  4. 5 or more

The correct answer is: 4 or more

A child fails the hyperopia test if they correctly identify 4 or more symbols in either eye. This criterion is used to determine if a child has sufficient visual acuity, as high hyperopia can impact their ability to see clearly. The test functions by assessing how well the child can recognize symbols, which reflects their visual clarity. If a child can identify 4 or more symbols, it indicates that they may have a level of hyperopia that warrants further evaluation or intervention. In contrast, being able to identify fewer symbols suggests that their visual acuity is likely within acceptable limits for their age group, making the threshold for failure set at 4 symbols. This approach ensures that any potential vision issues are recognized and managed in a timely manner.
