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 iris controls the amount of light entering the eye by dilating or constricting the pupil. In bright light, for example, the pupils shrink to the size of a pinhead to prevent too much light from entering. In dim light, the pupil enlarges to allow more light to enter the eye. Light then reaches the crystalline lens.
