The latest version of the iPhone and iPad includes a new feature that monitors the eye’s health, using the sensor built into the camera.
The feature is called “retina retinal” and it detects changes in light as a way to measure how well a person’s eyes are working.
It can help doctors determine when the eyes are tired or if they need to see a specialist.
The system works by using a small camera embedded in the screen of the device.
The camera can detect changes in the light in the eye as a signal to the retina that it needs to take more of a beating to stay healthy.
So far, it has been used to diagnose diabetes and some cancers.
“The retina is very sensitive, and the more it’s being stimulated, the more you need to be vigilant about keeping it healthy,” Dr. Mark Weiler, an eye surgeon at Stanford University, told Business Insider.
“If your retina is not working well, the eye may not respond the way you think it should.”
Retina retina sensors, which are manufactured by company Blue Shield, can be found in most of the devices we’ve reviewed in the past few months, including Apple’s iPad Air, Apple’s iPhone 7, and Samsung’s Galaxy S7.
They can also be found on the Samsung Galaxy Note 7, the Samsung Note 8, the LG V30, and even Google’s Pixel phones.
Google says the new feature works by detecting changes in blue light emitted from the retina.
That light changes the color of the retina in a similar way to the way the sun’s ultraviolet light changes our skin color.
But unlike the sun, blue light is not absorbed by the retina, so it doesn’t change the colors of the lens.
That means the blue light can be used to help the retina adjust to the blue in the environment.
The new feature can be turned on in Settings > General > Display and you’ll see a small box that reads: “This device has an LED sensor.”
The box indicates that the device’s screen is dimming to match the blue color of light in front of it.
The box also indicates that if the device is on the lowest setting, the retinas color changes.
This is the default setting, but if you turn it on the screen will change to the brightest color it can produce.
If you turn the feature on to the lowest level, it will automatically dim the screen to match your surroundings.
You’ll also notice a small blue LED at the bottom of the display.
This LED is the retina’s primary source of light and it can’t be dimmed or turned off.
If the device isn’t in the “dark” mode, it’s actually turning on the LED to illuminate it.
But if the LED is turned on, the device will stay lit for a few seconds as the retinal is contracting to adjust to more blue light.
To turn the LED on, click the “LED on” button and then click the LED’s “On” button to turn the light on.
This light can also have other functions, like turning off your phone’s backlight.
Retina sensors are typically used to measure the depth of the human retina, which is where light enters the eye.
But in the retina they can also detect changes that occur as light passes through the retina and into the eye, called excitation changes.
That can help determine when it’s time for the retina to contract and release more of the light it receives.
Because the retina is a small organ and doesn’t have a lot of room to expand, it needs the extra light to grow.
So if the retina can’t grow enough to compensate for the extra blue light it gets from the retina, it can cause more problems.
Retinas cells in the retinoid layer are also important in regulating the color in the cornea.
When a person has vision loss, the corneas absorb light from the external world, making it more intense in the surrounding area.
This intensity then changes the way light is reflected and refracted by the cornes.
This change in color can cause the corona to become distorted, which can make it harder for the corneum to seal properly.
This causes the corns color to change, which in turn can cause a corneal infection called conjunctivitis.
While there’s no cure for corneitis, doctors can use the new sensor to see how quickly the coronal color changes and to see if there’s any potential for improvement.
It also provides a way for doctors to identify a person with conjunctiva before they go into the hospital, and can also help doctors figure out whether someone has a disease or injury.
The Google retinas sensor can be adjusted to one of the brightest settings to match whatever color is in front.
The display on the iPhone 7 and iPhone 7 Plus can also display a small LED that can help the user determine whether the screen is dark or bright.
When the screen’s dark, it means the device doesn’t need
