This is because the difference between usual and post-meal blood glucose levels is not as large as in diabetic cases of hypoglycemia. A crash is usually felt within four hours or less of heavy carbohydrate consumption. Symptoms of reactive or postprandial hypoglycemia include:
The transverse size of a human adult eye is approximately 24.2 mm and the sagittal size is 23.7 mm with no significant difference between sexes and age groups. Strong correlation was found between the transverse diameter and the width of the orbit (r = 0.88).
The eye continues to grow, gradually, to a length of about 24-25 millimeters, or about 1 inch, in adulthood. A ping-pong ball is about 1 inch in diameter, which makes the average adult eyeball about 2/3 the size of a ping-pong ball.
