众所周知，人类和大多数动物的房水中抗坏血酸浓度非常高。它在眼睛功能中可能扮演的角色是一个猜测的主题。一些人提出，它可能会保护眼睛免受光线诱导的损害。我们检查了22种哺乳动物的房水，以确定其浓度范围，并确定其与行为是否存在相关性。在房水中发现了广泛的抗坏血酸水平。大多数被认为是白天活动的动物的抗坏血酸水平高于夜间活动的动物。这表明房水中的抗坏血酸可能对那些暴露在阳光下的动物起到保护作用。无论如何，任何提出抗坏血酸在哺乳动物眼睛中的作用的理论都必须考虑到抗坏血酸水平的广泛范围。
Ascorbic acid concentration is known to be very high in the aqueous humor of humans and most animals. The role it might play in ocular function is a subject of conjecture. Some have proposed that it might protect the eye against light-induced damage. We examined the aqueous humor from 22 species of mammals to determine the range of levels and to see if there was a correlation with behavior. A wide range of ascorbic acid levels in the aqueous humor was found. Most of the animals considered to be diurnal had higher ascorbic acid levels than the nocturnal animals. This would suggest that ascorbic acid in the aqueous humor may play a protective role in those animals who are most exposed to light. Regardless, any theory proposing a role for ascorbic acid in the eye in mammals must take the wide range of ascorbic acid levels into account.
