Blue Light Exposure: How to Protect Yourself Effectively?
5 (100%) 2 votes

Blue light is light produced by LEDs and displays: smartphones, computers, tablets, etc. Prolonged exposure – about half an hour – will disturb our body — sight and sleep disorders, headaches, etc..

It wreaks havoc on your bodies. Protecting yourself from it is essential to avoid negative effects. But how do we protect ourselves from blue light?

Protecting yourself from blue light: a necessity

Today, it is impossible to live without having contact with one or more digital devices. Whether we use it occasionally or as essential, we are in contact with blue light for much longer than thirty minutes a day. That is, the time it takes, approximately, to harm our body.

Blue light – or HEV, High-Energy Visible Light – is present in many artificial lights. It is very harmful to the eye, especially light-sensitive cells in the retina.

The eyes and head are intimately linked to each other; the vestibulo-ocular reflex is a gaze stabilizing reflex. That is the reason why blue light causes headaches and significant sleep disorders, in addition to vision disorders.

But other negative effects – not listed above – are also caused by blue light such as attention disorders, fatigue, lack of concentration in the long term and a decrease in productivity. 

It is, therefore, necessary to protect your eyes when you are looking at a screen, which carry this harmful light for your health. The urgent need is to find adequate protection against blue light so that you can still use digital devices without any risk. 

Although, some people work with computer and other digital devices and cannot, as may be advisable, reduce the time spent in front of their screens.

Would it be possible to reduce it?

There are plenty of ways to protect yourself from blue light. Are they effective? It all depends. 

The best option is to reduce blue light directly from your digital devices; protective filters, applications, or on the system preferences. 

What can we say about that? Reducing the power of HEV light is probably possible, but it does not block the right waves. Similarly, it is possible to reduce the brightness of the screens, which some people do to protect themselves from blue light waves.

Knowing that blue light is located within the screens and LEDs, dimming the brightness or placing a filter will not be of much use. At most, this will attenuate the light waves, but will not remove their harmfulness to the eyes.

However, it is the eye that must be protected since it is the one that receives the blue light and is affected by its dangerousness. The most effective anti-blue light solution is, therefore, the use of suitable glasses.

The anti-blue light solution

Glasses are the best option to fight blue light, with a filter specially designed to not only attenuate but especially to eliminate harmful waves so that they do not reach the eye and cannot act negatively on them.

For those who already wear glasses, it is possible to ask for lenses treated with a blue-light filter coating: this way, no need to change glasses to work in front of the screens.

Of course, people whose job it is to be frequently, or even consistently, in contact with screens are the most affected by HEV light, but also children and teenagers who are increasingly on their screens and spend a considerable amount of time there.

For those who do not wear glasses, it is recommended to have glasses treated with a blue-light filter coating. They can be worn every time you are on a screen. These treatments are specific to this light. 

You can add this treatment to the correction of your glasses, or it can be adapted to uncorrected glasses for those who do not need them. It will allow everyone to protect themselves against blue light waves.

Lusee.fr offers glasses that do not spoil the visibility of the screen and provide particularly good protection. A considerable improvement in physical condition is seen thanks to the use of these glasses.

They are among the most famous and effective against blue light, but many other opticians also offer adequate protection.

The benefit of glasses is their degree of protection compared to other means such as filters and applications: they are adapted to the eyes, which is not always the case for other solutions implemented.

If possible, it is, of course, recommended to spend as little time as possible in front of the screens to reduce contact with blue light. This advice is more significant when you already have vision problems, when you work for a long time on the screens (take advantage of the moments outside of work to stop being on the screens) and for children and teenagers.

Filters can also be an addition, a plus when wearing glasses, to enhance protection.

The longer the contact with HEV light, the higher the protection should be. It is essential to protect yourself as soon as possible, to prevent any problems you may have.

As soon as you start to have migraines, visual or sleep disorders, you should immediately seek the most effective solutions based on the time spent on screens. Indeed, not all solutions will work for everyone: a person who spends three hours in front of the screens will be less likely to develop risks related to HEV light than a person who spends eight hours on their computer to work.
