UV radiation (200-400 nm) is generally considered to be outside the range of visible illumination for mammals. The aim of this study was to determine if UV wavelengths can influence pineal physiology. Experiments on hamsters confirm that wavelengths as low as 305 nm are transmitted through the clear ocular media to the retina. Furthermore, low irradiances of broadband (340-405 nm) and monochromatic (360 nm) UV radiation are capable of suppressing high nocturnal levels of pineal melatonin in intact, but not blind, hamsters. These data indicate that the hamster eye and neuroendocrine system are able to detect and respond to near-UV wavelengths.
紫外线辐射（200 - 400纳米）通常被认为超出了哺乳动物可见光照的范围。本研究的目的是确定紫外线波长是否会影响松果体生理学。对仓鼠的实验证实，低至305纳米的波长能透过透明的眼内介质到达视网膜。此外，宽带（340 - 405纳米）和单色（360纳米）紫外线辐射的低辐照度能够抑制完整但非失明仓鼠夜间高水平的松果体褪黑素。这些数据表明仓鼠的眼睛和神经内分泌系统能够检测并对近紫外线波长做出反应。
