Abstract

Purpose: To evaluate the effect of different correlated color temperatures (CCT) of organic light-emitting diode (OLED) lighting on accommodative lag (LAG) and near work-induced transient myopia (NITM).

Methods: The refractions of 31 young adults (11 male) were measured with an open-field autorefractor at 33 cm after 30 and 60 minutes of reading under 4274 K and 1877 K. The initial NITM and LAG were assessed objectively at baseline and every 30 minutes. The use of two CCTs was determined in the order of the random number table.

Results: After reading under for 30 minutes, the mean LAG for low-CCT lighting was slightly lower than the high-CCT lighting (-0.97 ± 0.53 D vs -1.21 ± 0.50 D, P = 0.10); after reading for 60 minutes, the difference was significant (-1.09 ± 0.55 D vs -1.36 ± 0.51 D, P = 0.048). When grouped according to the degree of myopia, both mild myopes (-1.11 ± 0.43 vs -1.38 ± 0.60 after 30-minute reading, P = 0.38; -1.34 ± 0.27 vs -1.5 ± 0.54 after 60-minute reading, P = 0.53) and moderate myopes (-0.90 ± 0.57 vs -1.12 ± 0.42 after 30-minute reading, P = 0.16; -0.96 ± 0.61 vs -1.28 ± 0.50 after 60-minute reading, P = 0.05) presented lower LAG magnitude under low-CCT lighting than high-CCT lighting, while the difference was not significant. As for NITM, no significant difference has been found between two CCTs in any group.

Conclusion: Reading under low-CCT lighting (1877 K) had a lower LAG magnitude than reading under high-CCT lighting (4274 K), suggesting the potential usefulness of low-CCT lighting for reducing LAG magnitude during near work.

OLED照明相关色温对近工作致短暂性近视和阅读适应滞后的影响

目的：探讨有机发光二极管（OLED）照明中不同相关色温（CCT）对调节滞后（lag）和近工作诱发的短暂性近视（NITM）的影响。方法：在4274k和1877 K条件下，分别在30min和60min后，用裸眼自折射仪测量31例年轻人（男性11例）在33cm处的屈光度。在基线和每30分钟对初始NITM和LAG进行客观评估。根据随机数表的顺序确定两个cct的使用。结果：阅读30分钟后，低cct照明组的平均LAG略低于高cct照明组（-0.97±0.53 D vs -1.21±0.50 D, P = 0.10）；读数60分钟后，差异有统计学意义（-1.09±0.55 D vs -1.36±0.51 D, P = 0.048）。按近视程度分组时，轻度近视(阅读30分钟后-1.11±0.43 vs -1.38±0.60,P = 0.38；-1.34±0.27 vs -1.5±0.54,P = 0.53)和中度近视(-0.90±0.57 vs -1.12±0.42,P = 0.16；-0.96±0.61 vs -1.28±0.50,P = 0.05)，低cct照明下的LAG值低于高cct照明，但差异不显著。对于NITM，两组cct间均无显著差异。结论：低cct照明（1877 K）下阅读的LAG值低于高cct照明（4274 K）下阅读的LAG值，表明低cct照明对降低近距离工作时的LAG值可能有用。

期刊介绍： ''Ophthalmic Research'' features original papers and reviews reporting on translational and clinical studies. Authors from throughout the world cover research topics on every field in connection with physical, physiologic, pharmacological, biochemical and molecular biological aspects of ophthalmology. This journal also aims to provide a record of international clinical research for both researchers and clinicians in ophthalmology. Finally, the transfer of information from fundamental research to clinical research and clinical practice is particularly welcome.
