防蓝光眼镜真的有用吗？这些实用的护眼知识了解一下

如今，人们的日常生活已经离不开电脑、手机，但这些电子产品在带给人更多方便、乐趣的同时，也会导致眼睛疲劳、近视加深等视觉问题。

有人指出，“电子产品所发出的高能短波蓝光是造成眼干、眼涩、眼疲劳的罪魁祸首”，于是防蓝光眼镜应运而生，并且销量不俗。

防蓝光眼镜真能保护眼睛，还是只是一个市场噱头呢？在下结论之前，我们首先需要了解一下什么是蓝光？

Blue light is a type of electromagnetic radiation with a very short wavelength that produces a high amount of energy. While it's true that light can damage your eyes under certain circumstances, there's no scientific evidence suggesting that blue light is harmful to our eyes. But many people still think it is, which is why blue light-blocking glasses are so popular.

蓝光是一种波长非常短、能量巨大的电磁辐射。虽然在某些情况下光线确实会损伤我们的眼睛，但是目前并没有科学证据表明蓝光对我们的眼睛有害。不过许多人仍然认为蓝光确实有害，这就是防蓝光眼镜如此受欢迎的原因。

"Everyone is very concerned that (blue light) may be causing damage to the eye, and it's a valid concern, but there's no evidence it may be causing any irreversible damage," Dr. Rahul Khurana, clinical spokesman for the American Academy of Ophthalmologists, told Business Insider.
