Are your eyes strained and all exhausted after staring at the computer screen all day?
Do you get a severe headache after spending a day in the sunlight?
If so, you might be feeling the effects of getting exposed to too much blue light.
Too much exposure to blue light can leave your eyes fatigued, strained, and unfocused, leading to many more severe symptoms.
Although blue light is bad for your eyes, sometimes you can avoid it. This is certainly true for people who work in corporations. They need to sit at their computer day in and day out.
Fortunately, we have solutions in the form of Blue light glasses.
Before we can talk about blue light glasses, we first need to understand what blue light is all about and how it affects us.
Blue light is the part of a visible spectrum that the human eye can see. Simply put, the part of the light has the shortest wavelength and highest energy.
You would be surprised to know that blue light makes up almost one-third of all the light we see. This include –
- The Sunlight.
- Smartphone screen.
- LED lights.
- CFL bulbs.
- Tablet screens.
While other devices make up only a fraction of it. However, due to the number of people spending their time watching screens, the risk of blue light from the screen is much more harmful compared to the sun.
Almost all blue light passes through your cornea and lenses and reaches the retina. A small amount of blue light is not harmful to your eyes, but if the exposure is for an extended period of time, it can severely damage the eyes.
Here are a few ways in which blue light affects your eyes.
- Excessive blue light can affect your sleep pattern.
- It can lead to eye pain and strain and result in dried eyes.
- It can also lead to an eye disease known as macular degeneration.
- You might even experience severe headaches.
Despite knowing that blue light damages our eyes, sometimes it becomes impossible to avoid them. In that case, you need blue light glasses to protect your eyes.
Although there is hardly any evidence that proves blue light glasses are effective against blue lights, many people claim that they are effective.
Blue light glasses are a type of vision wear made up of special lenses. These lenses help you filter all the blue light and reflect it back. Experts advise individuals who are involved in seeing the light all day long to wear blue light glasses.
The principle on which blue light glasses work is simple. Blue light glasses protect your eyes by reflecting back the high-energy blue lights. This helps in reducing any potential eye damage.
Generally, the purpose of blue glass is to reduce the train from the eyes while working on the screen. However, it can also be used as a way to protect your eyes from any type of blue light.
The most current research was conducted in February 2021. The results clearly state that blue light lenses might not be an effective way to reduce digital eye strain symptoms.
The researchers used 120 users with eye strain symptoms. They each were handed down with glasses which were placebo or blue blockers. However, the users don’t know about this.
After the 2 hours of work on the computer, there was no significant feedback on how the glasses have helped them with their work. Even more, telling is that there was no difference in the eye strain score between the two groups.
This proved that blue light glasses don’t necessarily protect eyes from blue light.
While the research was genuine, there are many factors that might have affected the result of the research. For instance, the time was too short to find the real extent of stress an individual faces while sitting at their computer the whole day.
The other factor is that blue light might not even be the reason behind the stress and eye strain. With so many loopholes, it is really hard to tell whether or not blue light is beneficial.
However, there are many people who claim blue light glasses are effective against computer screens and mobile phones.
On that basis, let’s move on to the benefits of using blue light glasses.
We have already talked about blue light and how studies were not able to prove its effectiveness on eye strain. However, some people have used blue light glasses and claimed that blue light glasses really work.
Here are the benefits you can enjoy with blue light glasses.
- Reduce Strain On The Eyes: Working on a computer or using your smartphone all day can result in several problems. And it will not surprise you to learn that watching the screen for long periods can cause eye strain. Using blue light glasses will help you reduce the eye strain and the things that accompany it – headaches and blurred vision.
- Prevent Age-Related Macular Degeneration: There is more research needed to talk about Macular degeneration. But, as we know that blue light passes through your cornea and lenses and reaches the retina, blue light glasses can help mitigate the damage that prevents future eye problems.
- Help With Healthy Sleep Pattern: Exposure to too much blue light affects the circadian rhythm. It slows down or completely stops the production of melatonin. This prevents you from falling asleep. Expert advice to stop using any devices 2 hours before going to bed. However, if you can’t maintain that, using blue light glasses will be beneficial.
If you can relate to your situation and see how blue light glasses can help you, buy one for yourself from Eyebobs.
Eyeglasses to protect your eyes from blue lights come with a specific lens color. You may see different lens colors like orange, red, and even clear lenses. Despite the color differences, they all work on the same technology. All of them filter out blue light while allowing other rays to pass through.
Clear lenses are the most popular among all the colors available in the market. In fact, you can use these during the day when you are out and enjoy exposure to a healthy amount of blue light.
Now that you know the ideal type of blue-light glass lenses, it is time to find the perfect frame. It is a good choice to choose a frame that is comfortable for daily use. However, don’t forget about style. Look for a frame that is stylish and perfectly defines your taste.
To check whether the lens you hold in your hand is a blue light lens, you must conduct a blue light filter test. Ideally, most blue light glasses filter 30% of blue light and will have a blue tint on the lenses. Though this tint will not be visible when you are wearing it, you can definitely see it when you hold it in your hand and see the sky through it.
You must understand that the function of anti-glare lenses is not the same as blue light glasses. Anti-glare lenses reduce the impact of the glare of light coming out of the screen. However, they do not have the capability to block any spectrum. On the other hand, blue light glasses are specifically designed to prevent high-energy blue light from passing through the lenses.
This is one of the most common questions asked by our readers. And the answer is YES, you can. Since blue light is present in the natural light, you can actually wear them the whole day. This won’t negatively affect your eyes or cause any problems.
The yellow tint you see on your blue light glasses is there for technological reasons. The yellow tint you see helps filter blue light, which can harm your eyes. If you find that blue light protection glasses don’t have a yellow tint, they will probably be fake or offer minimum protection to blue lights.
Blue light is everywhere. You are exposed to blue light when you are outside under the sun, watching TV, or using your mobile phone. The blue light from these devices may not be enough to cause any visionary damage. However, they certainly increase strain on the eye.
While there is no clear evidence that proves blue light is the reason for eye damage, it is true that excessive exposure to blue light does result in dry eyes.
This is where blue light glasses help your eyes to protect from blue light coming out from the screen. Using blue light glasses, you can protect your eyes and the injuries that are caused by blue lights.
