Are Iris Scanning Safe For Your Eyes: In 2016, iris scanning was included in the galaxy note seven in 2017. The iPhone 10 was the first in the apple lineup to include face ID. Both technologies use our facial data to unlock our phones. And both companies have told us that their technologies are safe for our health. So what’s going on? Let’s take a closer look to see if face ID and iris scanning assets for our health.

Welcome to Dr. Locke, where we help you make the best decisions possible about your health. So

How exactly does face ID work?

Well, the answer, of course, is magic. Well, not exactly magic. Within that famous notch in the iPhone 10. There are the infrared dot projector and infrared flood illuminator. We can’t see infrared with our eyes. But if you look with an infrared camera, you can see that there are thousands of dots projected onto your face. A built-in infrared camera captures this image Samsung iris scanning also uses infrared technology. It uses an IR led to illuminate your eye and a built-in IR camera to capture an image of the IRS, “Are Iris Scanning Safe For Your Eyes”

So when it comes to safety, the real question becomes Is there any harm associated with projecting infrared light towards our face? And what is infrared light anyway, on the electromagnetic spectrum, infrared light sits right next to visible light. Infrared has slightly lower energy than visible light. Infrared is all around us.

Sunlight feels warm because infrared radiation is absorbed by our skin and converted into heat. Even our own body heat is emitted as infrared radiation. Thermal imaging cameras help us see infrared light given off by our bodies, “Are Iris Scanning Safe For Your Eyes” And you already have things in your house that use infrared, like your TV remote, but can

Infrared direct at your face cause harm?

To answer this question, I read this riveting 26-page document called the International Commission on non-ionizing radiation protection guidelines or limits of exposure to incoherent visible and infrared radiation. Well, that was a mouthful. Anyway, the first thing to say is that infrared radiation is classified as non-ionizing radiation, “Are Iris Scanning Safe For Your Eyes”, What this means is that infrared cannot cause cancer. The main effect of infrared on the body is that it generates heat, there are only two parts of your body that are exposed to infrared when face ID or iris scanning is on. And that’s your skin and your eyes.

When infrared hits the skin, it is converted into heat in extreme amounts. Infrared can cause our skin to burn. But as you know from using face ID that you don’t feel any heat on your skin. Because the amount of infrared is very low. So damage to the skin isn’t really an issue.

What about the eyes?

Well, we know that extreme amounts of infrared can damage the eyes. People who work in manufacturing steel or glass are working with very hot objects that emit a lot of infrared. Normally, when we look at something very bright, we tend to squint to help protect our eyes from damage.

But because we can’t see infrared, our automatic squinting mechanism can’t really help us here. In situations of extreme infrared exposure. People can develop cataracts and even lose some vision. At the front of the eye, there is the cornea, lens, and Iris, the lens and cornea should be transparent to let light through to the back of the eye. But high amounts of infrared can heat up the proteins in the lens, causing the lens to become cloudy. This is called a cataract.

Infrared can also affect the back of the eye called the retina

The retina is responsible for detecting light and converting it into brain signals. High infrared exposure can damage this detection mechanism and cause vision loss. But here is the important thing. It all comes down to the amount of exposure in cases of extreme exposure. Yes, infrared can cause damage to the skin and the eyes.

long term effects of exposure to infrared

On this point, the IC ni RP says current knowledge suggests that there are no effects of chronic exposure to infrared radiation below the exposure limits provided. I have seen articles on the internet from people who report discomfort after using iris scanning, or face ID.

It is possible that some people are more sensitive to infrared than others. But it is also possible to get eyestrain from other sources, such as using your phone on high brightness or using your phone for too long without a break. If you are worried about the effects of infrared, then the simple solution is to turn off face ID or iris scanning and see if you notice the difference.

There is a bigger picture of this issue. Technology is very quickly becoming part of our daily lives. Things like Bluetooth, Wi-Fi, face ID, iris scanning are everywhere. So as consumers of these products, I think it is important for us to understand these technologies and remain alert about potential health effects. Fortunately, you don’t have to do it alone. If you have a health question, bugging you, let me know in the comments and I’ll do my best to answer it.
