Understanding the Risks of Blue Light Exposure to Your Eyes

Blue light glasses have grown in popularity in recent years as more people become aware of the possible harm blue light exposure may do to our eyes and general health. So what exactly are blue light lenses, and how do they function?

Blue light is emitted by electronic devices such as smartphones, tablets, and laptops, as well as LED and fluorescent lights. While blue light is not intrinsically dangerous, studies have shown that excessive exposure can induce eye strain, headaches, and sleep disturbance.

Blue light lenses, also known as blue light blocking lenses, are a form of eyewear that filters out some of the blue light generated by electronic devices and other sources. Blue light lenses are a popular alternative for those who spend a lot of time in front of screens since they can be added to prescription glasses or purchased as non-prescription glasses.

Blue light lenses function by reflecting and absorbing blue light, preventing it from entering the eye. To prevent blue light, some blue light lenses have a yellow tint, while others have a clear coating that does not change the colour of the lenses.

Blue light glasses can help minimise eye strain and tiredness induced by prolonged screen usage, which is one of its advantages. After gazing at a computer for lengthy periods of time, many people develop symptoms such as dry eyes, headaches, and impaired vision. Blue light lenses, which reduce the quantity of blue light that enters the eye, can help ease these symptoms.

Blue light lenses may also aid in the improvement of sleep quality. Blue light exposure in the evening can disturb the body's normal circadian cycle, making it difficult to fall and remain asleep. Blue light glasses may help enhance sleep quality and promote improved overall health by minimising exposure to blue light, particularly in the hours leading up to bedtime.

While blue light lenses are typically safe and effective, they should not be used in place of basic eye care. Maintaining excellent eye health requires frequent eye exams, optimal lighting and screen posture, and taking regular breaks from screen usage.

Finally, blue light lenses are a popular choice for those who spend a lot of time in front of computers since they can help minimise eye strain and tiredness while also improving sleep quality. While blue light glasses are not a replacement for basic eye care, they can be a helpful tool for preserving excellent eye health in the digital era.
