What Do Blue Light Glasses Do?

Blue light glasses are designed to filter out blue light, particularly the kind emitted by digital screens and electronic devices. These glasses are becoming increasingly popular as we spend more time in front of screens for work and leisure. The science behind these lenses suggests they may help reduce eye strain and improve sleep patterns by blocking the blue light that can disrupt our natural circadian rhythms.

By understanding the impact of blue light on our eyes and health, individuals can make informed choices about using blue light glasses to their benefit. Whether it's for reducing discomfort or contributing to better sleep hygiene, these glasses offer potential advantages to our screen-centric lifestyles.

Decoding Blue Light and Its Impact on Eyes

Blue light has a short wavelength, which means it is the high-energy visible blue light that we encounter every day. This type of light is prevalent in digital screens, LED lighting, and even sunlight. Because of its high energy, blue light has the potential to cause more significant strain on the eyes than other colours in the visible light spectrum. The concern for safety limits regarding blue light exposure has led to a growing interest in protective measures, such as blue light glasses.
