Why Is Blue Light Filtering Necessary?

We are all familiar with the effects of blue light. This ray is responsible for a number of problems ranging from super dry eyes and headaches to blurred vision. In addition to these problems, blue light is also known to affect your health and sleep. To protect your family’s eyes from the harmful effects of blue light, you should use a blue light filter on your devices like using attractive and affordable glasses for your kids. Here are some benefits and some highlights of using blue light filters.

Ergonomics plays a role in filtering blue light

To protect your eyes from the harmful effects of blue light, try to use the 20-20-20 rule. This simple rule tells you to take 20-second breaks every 20 minutes. The same restrictions apply when it comes to your monitor. Keep your monitor at least an arm’s length away from your eyes. If possible, dim your monitor. It’s not hard to see things clearly with less contrast, but you might feel better after you’ve dimmed it. 

Factors that contribute to blue light

Almost everyone is exposed to some form of blue light. From LED lights to cell phones, people are exposed to high-intensity blue light throughout the day. This cumulative exposure is particularly harmful to our eyes, as it leads to deterioration of retinal cells and the development of age-related macular degeneration (AMD).

The ill effects of blue light are not yet fully understood, but we know it can damage the eyes. This light can damage retinal cells, resulting in decreased vision, macular degeneration, and cataracts. The central part of the retina is important for reading, driving, and recognizing colors. In addition, children’s eyes are still developing and vulnerable to ultraviolet light and blue light. Therefore, the damage from blue light is especially severe for children.

The sun’s natural blue light helps our bodies regulate our sleep and wake cycles. However, exposure to artificial blue light can interfere with our circadian rhythm. During the day, blue light helps our bodies regulate our moods, but it can interfere with this important internal clock during the night. Approximately 80% of adults use digital devices before bedtime. Exposure to blue light may also affect the development of disease.

Benefits of wearing blue light glasses

There are many benefits of wearing blue light glasses. They can help reduce digital eye strain, but they can also protect your eyes from the damaging rays of artificial lighting. The glasses are not recommended for use in natural light, however. Tokyo-based JINS Eyewear has developed a special lens that combines style and technology to reduce the harmful effects of digital screens. The JINS SCREEN technology has been clinically proven to reduce eye strain caused by digital screens.

One study showed that wearing blue light glasses improved the duration and quality of sleep. However, the study was too small to draw any firm conclusions. Additional research is needed to confirm the benefits of blue light glasses for everyone. Furthermore, it has been noted that exposure to digital screens may cause symptoms such as headaches and computer vision syndrome. The most at-risk group spends several hours a day on their computers. Therefore, blue light glasses are an excellent choice for these people.

Studies have shown that blue light glasses may improve sleep in those who have insomnia. The amber tint of the lenses reduces the suppression of melatonin, a hormone that promotes sleep. However, a systematic review published in Chronobiology International did not measure melatonin levels in those who used blue light glasses. Therefore, the results were mixed. As a result, the researchers could not conclude which group would benefit more from blue light glasses.
