There is usually no difference between night vision and day vision.
Eye vision generally consists of both central vision and visual field vision.
Central vision is more sensitive to bright light and can only see clearly in a well-lit environment, but visual field vision is also very sensitive to weak light and can see colors and shapes clearly both day and night. Therefore, there is usually no difference between night vision and day vision.
When taking a vision test, be careful not to tilt your head or squint, keep both eyes flush with the 5.0 vision chart, and be careful not to rub your eyes excessively. Avoid rubbing your eyes with your hands during the test to avoid inaccuracies in vision due to pressure on the cornea.
If you experience any discomfort in your eyes, you should seek medical attention promptly to avoid delaying your condition.
