When you stare at a screen for hours at a time, whether it is a computer, TV, phone or tablet, you are exposed to blue light from the device. Alarmist headlines claim blue light from too much screen time is blinding us. But there is no scientific evidence that blue light from digital devices causes damage to your eye.
Exposure to blue light before bedtime also can disrupt sleep patterns as it affects when our bodies create melatonin. Interruption of the circadian system plays a role in the development of type 2 diabetes, cardiovascular disease, cancer, sleep disorders, and cognitive dysfunctions.
If research proves that blue light damages the retina and macula, the eye conditions that develop as a result are generally irreversible. Treatments can only delay vision impairments or improve vision to only some extent and stop these eye conditions from worsening.
This high energy blue light passes through the cornea and lens to the retina causing diseases such as dry eye, cataract, age-related macular degeneration, even stimulating the brain, inhibiting melatonin secretion, and enhancing adrenocortical hormone production, which will destroy the hormonal balance and directly ...
The amount of damage depends on wavelength and exposure time. Animal studies show even short exposure (a few minutes to several hours) may be harmful. A filter that cuts 94% of blue light has been shown to lessen damage. There's evidence blue light could lead to permanent vision changes.
A recent study suggested that blue light-blocking glasses do not improve symptoms of digital eye strain. The American Academy of Ophthalmology does not recommend blue light-blocking glasses because of the lack of scientific evidence that blue light is damaging to the eyes.
It usually takes about two to six weeks to fully heal after PDT, depending on the area of your body that's being treated.
When you stare at a screen for hours at a time, whether it is a computer, TV, phone or tablet, you are exposed to blue light from the device. Alarmist headlines claim blue light from too much screen time is blinding us. But there is no scientific evidence that blue light from digital devices causes damage to your eye.
Blue light blocking lenses should be worn anytime you are using a screen or device that emits blue light. Keep your eyes healthy and reduce digital eye strain with a great pair of blue light blocking lenses.
You can easily reduce blue light by activating Night Shift on your iPhone. This is an integrated iPhone blue light filter app and is also available for the iPad and Mac. The Night Shift feature in iOS allows you to filter out some of the blue light emitted by your iPhone display.
Most Android devices should have built-in blue light filters that can be enabled or disabled from the Settings screen. However, the feature's availability and options depend on your specific device and version of Android.
Research suggests your eyes respond to yellow light more than blue light. It turns out that smartphone features like Night Light and Night Shift — which tint the screen to reduce blue light and help users fall asleep — don't actually help users fall asleep. In fact, tinting your screen may actually be worse.
Using Night Mode on Your Device
With reduced white colors and minimal contrast, the Night Shift can, in turn, reduce the blue light emission. Most phones' night mode will automatically adjust when the battery is low or it detects a low-light environment.
Dark mode doesn't directly reduce eye strain, but it can offer some relief. For example, in a dim setting, a bright screen has your eyes working harder. On the contrary, a dark screen in a brightly lit room will have the same effect. -Easier to read.
Wearing blue light glasses may sound like a good solution, but a recent study determined there was little evidence to support the use of blue-blocking filters in the prevention of digital eye strain.
And this is where privacy screen protectors come in handy. They can reduce the amount of blue light emitted by your device, which decreases the effects of the blue light. You will still get exposed to it, but the effects will be reduced.
Is it bad to sleep with your phone beside you? Yes, usually speaking, it's not a good idea to sleep with your phone nearby. Sleep quality may suffer if you keep your phone close to your head while trying to slumber because it emits electromagnetic radiation.
Experts say adults should limit screen time outside of work to less than two hours per day. Any time beyond that which you would typically spend on screens should instead be spent participating in physical activity.
ROSENFIELD: Both of the studies actually found that the blue-blocking filters have no effect, no significant effect on digital eye strain. This didn't really come as a major surprise to us because there really is no mechanism whereby the blue light should be causing digital eye strain.
Clear Lenses
Many blue light glasses now offer a clear lens which looks as though you are wearing regular glasses. The only difference is they may have a purple, blue or green reflection when someone looks at your blue light glasses. These blue blockers are often called computer glasses.
