Do Blue Light Glasses Work To Help Eye Strain?
In today’s time, it becomes impossible to spend a day with the digital screen, like tablets, mobile phones, laptops, or even televisions, and this is the reason the eyes and sometimes the head too are getting punished for using these gadgets for long hours. That’s where blue light glasses come in. But here’s the big question: Do blue light filter glasses work?
In this blog, we’ll explain what blue light is, what blue light filter glasses do, and whether they actually help your eyes.
What Is Blue Light?
Have you ever observed the sharp light in your eyes from digital devices like laptops, phones, TV even from the sunlight?
That is the blue light. One thing which is important to understand is that the light is not always harmful.
In fact, we get a more active and awake mode from the blue light we get from the sun during the day. But we must also understand the fact that too much blue light is not good for our eyes, especially from digital devices at night.
- Eye strain
- Headaches
- Dry eyes
- Trouble sleeping
Where Does Blue Light Come From?
- Blue light comes from two sources
- Naturally: from the sun.
- Artificially: from digital screens (phones, computers, TVs, LED lights)
While natural blue light is comparatively safe as it is balanced with other types of light & artificial blue light from screens is more direct and we look at it for longer periods.
What Are Blue Light Filter Glasses?
Blue light glasses have special lenses that are designed to block or filter out some of the blue light that comes from screens. These glasses are often called
- Blue light filter glasses
- Computer glasses
- Anti-blue light glasses
They’re advertised to help with:
- Eye fatigue
- Headaches
- Better sleep at night
- Better focus during long screen time
Do Blue Light Filter Glasses Work?
This is the question everyone wants answered, and the answer is yes, they do but not for everything.
What They May Help With:
- Eye strain: Some people admit that they feel their eyes are less tired after wearing these glasses for long hours of work.
- Headaches: If your headaches are caused by screen light, glasses with blue light might reduce them.
- Sleep: Using a digital device at night, especially at the time of sleep, affects the sleep cycle badly. The reason is that blue light blocks the production of melatonin (the sleep hormone). These glasses can reduce that effect to some level.
What They May Not Help With:
- Serious vision problems: They won’t fix vision issues like nearsightedness or dry eyes.
- Long-term protection: Research is still going on. Some experts believe the effects are small, and better screen habits may help more.
Can Blue Light Glasses Be Worn All Day?
Yes, you can wear blue light glasses the entire day, there is no restriction on it, and no side effects either, as these are specifically designed to block the blue light and keep the eyes safe from getting tired and vision affected.
Remember to put on sunglasses when going out during the day. It is better to put on sunglasses so that your eyes will get protection from the ultraviolet rays, too.
Also, it’s okay if you skip the glasses if you are working lightly, but in darkness or working for prolonged hours, the blue light glasses are a must. So, there is no problem in wearing the blur filter glasses the entire day.
When Should You Use Blue Light Glasses?
You may benefit from using blue light filter glasses if:
- You spend 5+ hours a day on your computer or phone
- You work or study on screens for long hours
- You watch screens at night before bed
- You often feel eye strain, dryness, or blurry vision after screen time
- You’re a gamer, graphic designer, or content creator
They are also useful for kids and teenagers who use digital devices a lot.
Are Blue Light Glasses Worth It?
Blue light glasses are available at a reasonable rate and have no known side effects. If you are someone who needs the digital screen mandatorily for the purpose of work, running the business, or for doing research or studying, even just to scroll social media, then yes, the blue light glasses are worth using.
They not only protect the eyes from the blue light but also improve life’s quality by giving relaxation from the headaches and eye strain issues that are directly linked to the usage of digital devices.
Do Blue Light Glasses Prevent Damage To The Retina?
This question is raised by many people whose maximum time is spent in front of a digital screen, and they can’t ignore it, as their work depends on these devices.
They asked if there is any harm to the retina from the blue light, as the retina plays a huge part in helping to see clearly.
Here’s the truth:
Till now, it has not been proven that blue light is responsible for the retinal damage, as the blue light that is emitted from the screen is much less in comparison to that emitted from the sun.
So, while blue light glasses usage gives relief from the digital eye strain to a major extent, although it is not advisable to just rely on these, ensure to take regular breaks in between so that the eye muscles also feel relaxed and, ultimately, the eyes don’t feel tired.
Well, there is no direct impact on the retina from the blue light, the glasses are meant to fix the digital eye strain, which is the major concern for those who spend more than half of the day using digital devices.
Other Ways To Protect The Eyes From Screen Light
Even if you wear blue light glasses, it’s a good idea to follow these tips. Remember, taking care early saves money later. Here’s how you can prevent further strain:
- The powerful rule of 20
In every 20 minutes of focused work, look at something that is away, at least 20 feet, for a minimum of 20 seconds. - Use Night Mode on Devices
The active night mode helps decrease the blue light emission from the screen, which is good for eye health. - Reduce Screen Brightness
The brightness level should be based on your surrounding light conditions. - Take Screen Breaks
Do not work in one sitting for long hours, ensure to take breaks in between to get your eyes and mind both feeling relaxed. - Blink Often
The eyes get dry if the blinking is disturbed, and in doing intense work, we often forget to blink our eyes, so be sure to blink during work, as it helps you to feel less uncomfortable while working.
