Scientists have come to realize that blue light has a negative impact on the eyes at night. During the daytime, humans are accustomed to seeing blue light, which keeps them awake. The exact same thing happens at night but in an unnatural manner. Exposure to blue hues tires out the eyes, causing eye strain and worse. In fact, overexposure in the evening can lead to trouble falling asleep later that night.
Fortunately, blue light glasses are available to help combat fatigue and strained eyes. Specialized glasses filter out blue hues and prevent such issues from occurring. Most pairs of these glasses put a yellow tint on everything to filter out blue. However, a handful of other filtering options are sold on the market today. Many individuals will experience less strained vision and better sleep at night by switching to filtered glasses.
