Nowadays, people tend to spend more time using digital devices, whether watching television or using phones and tablets. People in these groups are most exposed to blue light because of the increased use of LEDs, organic LEDs, and active-matrix organic LEDs in technology. 

Blue light can cause fatigue in your eyes, loss of focus, and cause many other symptoms. That's why it's a great relief to find that blue light glasses can filter out the blue light and reduce its harmful effects.

What Is Blue Light?

Smartphones, computer screens, televisions, office fluorescent lights, and the sun emit blue light. Everywhere you look, there is blue light. All colors of light are present in the sun, including red, orange, green, and blue. However, the energy level of each color varies. For example, red and orange have longer wavelengths and less energy. Blue light consists of the shortest wavelength and contains the most energy in the spectrum of light that the human eye can see.

Blue light is primarily emitted by the sun when you are outside, but people are now exposed to more of it indoors - especially from too much screen time. Thus, eye care professionals are concerned about this excessive exposure.

What Are Blue-Light-Blocking Glasses?

The blue light glasses are specifically designed to block or filter out the blue light. By wearing blue-light-blocking glasses, people can reduce eye strain, eye damage, and sleep disturbances. Blue light blocking glasses haven't been the subject of much research, but some studies indicate that they may:

 

• Preserve macular health
• Enhance visual performance
• Improve sleep quality

The American Academy of Ophthalmology recommends wearing eyeglasses instead of contact lenses for prolonged use of electronic devices. Although blue light glasses might not be suitable for everyone, they may reduce the effects of prolonged exposure to blue light on the eyes. 

5 Reasons Why You Should be Wearing Blue Light Glasses

When exposed to excessive blue light, you need to wear blue light protection. You can benefit from wearing these glasses in five ways.

 

1.Prevents Eye Strain

 

Blue-light glasses can be one way to ease digital eye strain in either case. This specialized eyewear filters blue light and increases contrast, allowing you to focus more easily and preventing eye strain. Get computer protective glasses with yellow lenses if you wish to enjoy viewing digital devices for long periods. However, various factors can lead to eye strain, so it is always advisable to seek medical/optical advice whenever possible.

 

 

2. Reduces Your Eye Disease Risk

 

Too much exposure to blue light can increase your chance of developing eye diseases such as cataracts. The blue light can penetrate through the cornea and then reach the retina.

Indeed, it is true that your cornea and eye lens can block harmful UV light from reaching your retina, but they cannot block blue light. So, wearing blue light glasses can reduce the detrimental effects of constant exposure to blue light, which will reduce your risk of getting eye diseases.

 

 

3. Provides Better Sleep

 

Blue light can negatively affect your normal waking and sleeping cycles and the quality of your sleep. Moreover, blue light in the evening can hinder your body's ability to produce melatonin.

 

Besides affecting your body's production of melatonin, blue light also disturbs your natural body clock. You may find it difficult to sleep at night and get up in the morning if your brain associates blue light with daytime. Likewise, you can minimize this effect by avoiding screen time 30 minutes before sleeping. As an alternative, putting blue light glasses on before sleeping while using your smartphone can also help mitigate the effects of blue light exposure.

 

 

4. Protects the Eyes From Dryness

 

Even though dry eyes sound like a minor issue, they can be very distracting when trying to concentrate or driving after a few hours of online gaming or working. In addition to this, dryness may cause you to rub your eyes excessively, causing them to be sore. Make your screen time more comfortable by blocking out the blue light by wearing blue light glasses to prevent your eyes from drying out.

 

 

5. Ensures That You Can Use Your Devices Longer Without Worrying.

 

Nowadays, most of your daily tasks require that you use your smartphone, tablet, or computer, which may keep you glued to the screen for hours each day.

These devices emit blue light, which bombards you continuously. By wearing blue light glasses, you can protect your eyes without increasing your risk of vision problems. Children who wear computer glasses are also more likely to maintain good eye health. While it is also common for kids and teens to use technology for learning purposes, you should encourage them to wear blue-light-blocking eyepieces whenever they use their computers and mobile devices.

 
Key Takeaway

While we can't do anything about the effects of blue light exposure on our health, we can take steps to manage its effects, like wearing blue-light-blocking glasses. Remember that the most effective way to reduce your exposure to blue light is to limit your time looking at your devices or follow the 20-20-20 rule.

Therefore, you can prevent eye problems and keep your eyes healthy.
