What Are Anti-Blue Light Films & What to Look For Before a Purchase

By October 10, 2019 No Comments

Many modern jobs require people to work in front of their computers for long periods of time. Accountants, lawyers, customer service agents, account managers, writers, and more rely on technology and the internet to get their jobs done. Whenever we need information about current events or the new cafe down the street, we head to Google. Even outside of work, we spend hours in front of our TVs or mobile phones. 

Although there are definitely upsides to the technology we have today, long exposure to computer and mobile screens can lead to a series of eye-related health problems. A few common issues are soreness, pain, eye strain, retinal dysfunction, blurred vision, conjunctivitis, dryness, and more. These problems are caused by blue light or electromagnetic radiation from the screens on your computer, tablet, or mobiles. 

To reduce the impact of blue light or electromagnetic radiation, you may need a blue light filter. Keep reading to find out more about blue light and why you should seek blue light filters to keep your eyes away from harm.

What is Blue Light?

Blue light is not a special light only omitted from LED lights or computers—it is all around us. In fact, sunlight is the main source of blue light and the reason why we see blue skies.

These light waves are bounced around and reflected at every corner of the Earth’s atmosphere. In today’s world, blue light is everywhere. The sun is not the only source of blue light anymore—artificial sources of blue light are digital screens, electronic devices, fluorescent lighting, and LED lighting. 

There’s nothing wrong with blue light in small doses, but with many of us spending hours a day on our screens at close proximity, health practitioners and eye doctors are getting worried. Anti-blue film is recommended to lessen the harmful effects of blue light on your eyes and improve your overall health.

What are Anti-Blue Light Films?

Unlike ordinary screen protectors, the anti-blue film is made of special material—a nano-lamellar optical film. This film will not only block up to 90% of blue light but also maintain up to 95% of transmittance. In short, this means that it effectively blocks blue light while reducing the risk of eye problems caused by overexposure. 

With so many products available in the market, it can be confusing and difficult to determine whether an anti-blue film can efficiently block excessive blue light rays. Fortunately, we know just what you should be looking for. Keep reading to learn more! 

What You Should Be Looking For When Buying Anti-Blue Light Films

1 – High Blue Light Blocking Capacity

One thing to look for when getting a blue light filter for your screens is its capability to block blue light. Check with the manufacturer to find out the exact information, as some films block a mere 30% of blue light while others can block up to 98%.

2 – Device Compatibility

Anti-blue light films are not all alike. Make sure that the screen protector you are buying is compatible with your device. After all, an iPhone 7 screen protector will not be compatible with a Sony phone.

3 – High Blue Ray Protection Value

Effective blue light filters should have blue light protection rates of 99.9%. This can effectively filter and reduce the amount of blue light scattered by your computer or mobile screen, reducing eye strain and fatigue.

4 – Reasonable Thickness 

Anti-blue films should be reasonably thick. Ideally, commercial polarizing manufacturers develop anti-blue film with a thickness of 0.1mm under the basis that it will achieve 99% blue light protection.

5 – Minimal Visual Distortion

A good anti-blue film should be able to reduce the colour shift and colour discolouration rate, making it so that you don’t need to adjust your screen’s brightness.

Prevention is better than cure. It is important to take care of your health at all costs. Protect yourself from the harmful effects of blue light. To learn more about blue light and how to purchase good quality anti-blue light film, contact Ocushield today!
