Blue light is around us every day in many forms. With digital devices becoming more common, we are also looking at more sources of blue light. Blue light reduction glasses can help to relieve eye strain by balancing the light coming to your eyes. If you have blue light glasses, they can be worn safely all day long.
Whether it is a cell phone, computer or tablet, blue light comes to us from many different sources throughout our day. When blue light is emitted from screens, it scatters, which makes it difficult for your eyes to focus. Blue light lenses can help reduce the eye strain caused by digital devices.
There are many people that have symptoms of digital eye strain, and 58% of Americans have experienced symptoms as a direct result of screen use. Eye strain caused by prolonged exposure to blue light can lead to eye irritation. Whether you wear glasses for corrective issues or do not wear glasses at all, you may still benefit from glasses that filter blue light.
What is Blue Light?
The visible spectrum is measured by the light that the human eye can detect. These measurements consist of wavelengths of light from approximately 380 to 700 nanometers.
Blue light is measured on the lower end of the light spectrum at roughly 400-490 nanometers. This is in the range of visible light and has a high amount of energy that often contributes to digital eye strain.
Even if I Do Not Wear Glasses Regularly, Are Blue Light Lenses Right for Me?
Screen time has become a part of many people’s daily routines. Many of us need to be in front of a digital screen for prolonged periods of time for one reason or another and could be bothered by the effects of digital eye strain.
Even if you do not normally wear glasses, wearing blue light lenses while using digital devices can help reduce some of the uncomfortable symptoms of digital eye strain.
There are different signs and symptoms to watch out for that could indicate that you are experiencing eye strain, such as:
- Eye fatigue
- Sore or burning eyes
- Difficulty concentrating
- Increased sensitivity to light
- Double or blurred vision
- Sore shoulders, neck, or back
- Dry eyes
Should you experience one or more of these symptoms on a regular basis after interacting with devices or screens for long periods of time, blue light glasses may be helpful for you.
While some of the symptoms of eye strain can be alleviated by limiting your screen time, there are other ways you can reduce some of the everyday strain on your eyes.
Keeping your screen at a further distance from your eyes, around arm’s length, can help reduce the strain on your eyes. Working in a room that is brighter, so that you are not depending only on the light from your screen, can also help. Giving your eyes a break throughout your day can also help reduce eye strain and may help increase productivity.
Wearing blue light glasses in addition to the strategies above may help reduce eye strain and related symptoms like dry eyes.
Do Blue Light Glasses Work if They Are Not Used For Corrective Purposes?
Even if you do not normally wear glasses to fix a corrective issue or disease, blue light glasses can help reduce the strain on your eyes caused by digital devices affecting your vision.
Your eyes are exposed to various sources of light every day. A lot of this light comes from the sun, while some of it comes through overhead lighting and digital screens. Whether you are being exposed to natural or artificial light throughout the day, there is often some form of blue light coming to your eyes. Blue light from digital devices is often less intense than blue light that comes from natural sunlight.
There can be both positive and negative effects from different levels of exposure.
Some of the positive effects of blue light include:
- Boosted alertness
- Elevated mood
- Memory improvements
Some negative effects of blue light are:
- Interrupted sleep cycles and poor sleep
- Difficulty falling asleep
- Tiredness and fatigue throughout the day
