Effects Of Blue Light On Our Health

The positive effects of blue light on our health are well-known. This wavelength of light helps us to wake up in the morning and is very beneficial during the day. However, it is detrimental during the night as it reduces melatonin, a natural sleep hormone. Furthermore, blue light interferes with our circadian rhythm and disrupts our natural ability to sleep. This light also tricks our bodies into believing it is still daytime, thus making it harder to fall asleep.

Damage The Retinal Cells

Studies have shown that the effects of blue light on the human body are accelerated in people who are exposed to it for long periods of time. These effects are a cause of concern, as blue rays damage the retinal cells that are responsible for seeing. Exposure to blue light can accelerate age-related macular degeneration, which can result in vision loss. This effect has been linked to increased risk of glaucoma, heart disease, and depression.

Exposure To Digital Screens

Children are particularly vulnerable to digital eyestrain because they are constantly surrounded by screens and other devices. A study by the Kaiser family foundation in 2006 revealed that children spend over seven hours per day on digital media. Because children’s eyes are not fully developed until they reach the age of 10, they are exposed to blue light at higher levels than adults. And too much blue light is not good for your eyes, which is why limiting their exposure to digital screens is vital.

Long-term Effects

There are other negative effects of blue light, but for now, it is not believed to have any long-term effects on our eyes. While this type of light may not have the harmful side effects, research suggests that it can accelerate age-related macular degeneration. Those who are regularly exposed to blue light should avoid it as much as possible. In fact, blue lights are beneficial in the long run, as they improve our mood and memory.

Temporary Discomfort And Sleeplessness

The effects of blue light on the eyes are not as immediate as you may think. They may lead to temporary discomfort and sleeplessness. But they will not cause macular degeneration or permanent eye damage. Researchers are still concerned about this impact of screens on our eyes. If we use our devices too much, we may be contributing to this problem. In the meantime, we should limit our use of electronic devices. We must make sure that we get enough sleep and recover from the effects of blue light on our health.

In Summary

The blue light from digital devices can damage our eyes. This light is responsible for the creation of images in our brain. For that reason, you should avoid it. The more blue light you are exposed to, the more it will harm your eye. This is especially true if you work late at night. If you can, switch to brighter lights during the day and dim lights during the evening. This can regulate your exposure to blue light in your eyes and make it less damaging.
