The correct answer is: True

Glare from windows or overhead lights can significantly impact the results of a vision test. Glare can cause discomfort and strain, making it difficult for individuals to see clearly. This affects their ability to accurately perceive visual stimuli during the testing process, potentially leading to incorrect results. Proper lighting conditions are essential for ensuring that vision tests accurately reflect an individual's visual capabilities, highlighting the importance of managing glare in testing environments. Therefore, recognizing that glare can interfere with test outcomes supports the assertion that the statement is true.
