Introduction
AR coating, short for anti-reflection coating, is also known as glare-free or no-glare coating names. So why is anti-reflection coating needed? This coating is usually only known for its uses, such as making the glasses easier to clean or preventing oil and dirty water from sticking to the lenses.
This coating has many other uses. It not only helps protect your eyes but also enhances their aesthetic beauty!
However, all the benefits mentioned above are not the ultimate power of this coating. It can also improve your vision (even in the dark). Getting excited already? Continue reading our article to learn more!
#1. Protect Your Eyes From Sun’s Damaging Rays
Ultraviolet rays are among the most harmful rays to humans, especially the eyes. This ray comes from the sun, so your eyes can be quietly affected sometimes. It is also the main culprit that causes cataracts and cancer.
However, you can avoid these dangerous diseases with an AR coating. It will protect your eyes from UV radiation. According to scientific research, in the absence of certain external factors, AR-coated lenses' UV reflection rate can be up to 25%, 10 to 20% more than non-AR-coated lenses.
Besides, if this protective layer is added to the back of the glasses, your eyes will be protected from the dangerous UV rays reflected on the sidewalk or windows.
Also, if you have an optical (transition) or polarized lens, the protecting ability will be significantly enhanced. You can consult the experts at the eye clinic for more details.
#2. Increase The Life Of Your Glasses
After a long time of use, our daily activities will often cause scratches on the lenses. If there are too many scratches, the lenses can become unsightly and reduce visibility. You may have to buy a new one because of this reason.
No need to worry because the AR layer will solve this problem. It can reduce direct physical impacts on the lenses and incorporate dirty water and oil. Thereby, it increases the lifespan, reduces the frequency of glass replacement, and saves you money.
Every manufacturer has its anti-reflection coating formulation. But in general, all formulations have microscopic layers of metal oxides. These oxide layers are why anti-glare covers have reflection reducent and scratch prevention ability.
The more oxide layers, the better AR cover's quality. Some high-quality coatings can have up to 7 oxide layers. You should consider the layer's quantity before choosing a no-glare cover.
#3. Protect Your Eyes From Blue Light
Almost everyone is regularly exposed to blue light in today’s technologically advanced age. This type of light is very harmful to human eyes. It causes eye fatigue, discomfort, and vision reduction.
Usually, standard covers can only block reflections. That's why anti-reflection cover manufacturers create special AR layers that prevent the "meeting" of blue light and the eyes.
Blue-light-block anti-glare coating is a fairly effective anti-blue-light layer. It is specially formulated to block a certain percentage of harmful blue light from passing through the lenses. However, it still allows beneficial blue light to reach users' eyes.
People wearing this coating type will often have gentle blue glitter on their glasses. This phenomenon occurs because the glass reflects harmful light.
In addition to harmful light prevention, this cover can also block glare. That's why it is suitable for office workers and remote workers.
#4. Increase Visibility
An AR layer can bring many benefits to its owner, from aesthetic appearance to beauty to eye protection. But the biggest benefit is still the vision-increasing ability. So, where do these capabilities come from, and why is it necessary?
Normally, not all light passes through the glasses into the user's eye. Some light will be reflected. This makes eyes with glasses' visibility worse than normal ones. To be specific, normal glasses' materials such as plastic will reflect about 8% of light. In other words, your eyes will see at least 8% worse.
With no-glare coating, the percentage of light entering the eye will be up to 99.5%. Only 0.5% of light is reflected, which helps your eyes see more or less 99.5% as clearly as ordinary people. In short, your eyesight will be significantly improved.
Besides mentioned ability, this coating will also improve night vision for the wearer. Thanks to its light reflection reduction ability, the glare from street lights or headlights of vehicles in traffic will decline.
#5 Improve The Aesthetic
An unexpected strength of the no-glare coating is its ability to improve your appearance.
Eyes are the biggest contributor to a person's beauty. Some people even judge a person by looking at others’ eyes. However, normal glasses will cause reflections when light hits them. As a result, your eyes will now be replaced with annoying light reflected on the lenses. This leads to a decrease in your attractiveness.
No worries, because with just a good coating, the light will now be able to pass through your lenses and no longer be reflected. Your glasses can even become almost invisible in all lighting conditions. Thanks to that, other people will see your eyes and facial expressions more clearly, even when the glasses are hit by direct light.
Besides, an anti-glare cover is just metal oxide layers coated on the front or back of the lens. Therefore, it is not annoying and does not thicken the user's glass.
With amazing performance and does not cause loss of aesthetics, this cover is loved by many people. Many manufacturers even consider this coating to be part of the finished glass.
Conclusion
So why is anti-reflective coating needed? This type has a lot of different capabilities that benefit users. It improves eyesight, resists dirt, prevents water, protects the eyes, and increases the aesthetics of the wearer.
Many users review that AR coating is a good investment in eye health. However, you should consult your optometrist to get the right anti-reflection coating type.
