Product Information

elevating our body temperature and heart rate. During the day, blue light can improve performance and attention, tuning our circadian rhythms and setting us up for a better night’s sleep after the sun sets.

Blue light filters reduce the amount of HEV blue light emitted from these devices from reaching your eyes without affecting the visibility of the display. Some are made with thin tempered glass that also protects your device's screen from scratches. Learn to dim: Dim the brightness of your electronic screens, or use the “night mode” feature found on some devices. Some studies suggest a link between exposure to light at night, such as working the night shift, to diabetes, heart disease, and obesity. That's not proof that nighttime light exposure causes these conditions; nor is it clear why it could be bad for us. If you have cataracts and are about to have cataract surgery, ask your surgeon what type of intraocular lens (IOL) will be used in your procedure. Some IOLs may be better than others at restoring some level of blue light protection for your retina after surgery. You can damage a retina if you point strong blue light at it for long enough, which is why we don’t look directly at the Sun or LED torches. Why is blue light used by some doctors?So far there’s no evidence that blue light from devices is a culprit. Computer users tend to blink five times less than usual, which could result in dry eyes. And focusing on anything for long periods without a break is a recipe for tired eyes. Beaulé, C.; Robinson, B.; Lamont, E. W.; Amir, S. (2003). "Melanopsin in the circadian timing system". Journal of Molecular Neuroscience. 21 (1): 73–89. doi: 10.1385/JMN:21:1:73. PMID 14500998. S2CID 18390790. Each color in the visible light spectrum has a different wavelength and energy level. Blue light has shorter wavelengths and higher energy than other colors. Some research shows a link between eye damage and short-wave blue light with wavelengths between 415 and 455 nanometers. Most of the light from the LEDs used in smartphones, TVs, and tablets has wavelengths between 400 and 490 nanometers. Declan Lawn and Adam Patterson say: “Every writer wants to explore their own place, and their own society as authentically and as honestly as they can. We feel enormously grateful to BBC drama for letting us do that with Blue Lights. And to do it with a cast boasting so much new and established talent makes it even more exciting.” AMA adopts guidance to reduce harm from high intensity street lights".

The FDA doesn’t view blue light glasses as medical devices, either, and it may be too early to claim certain benefits or harm prevention conclusively. Adjust the contrast on your screen or the lighting in the room. More contrast will reduce eye strain. A study by the US National Institutes of Health writes that "More than one-third of wearers found that a clear lens with a blue-filtering coating (BT lens, which all limit blue light up to 20%) provided better anti-glare performance and improved their vision for computer and mobile digital screens."In moderation, however, UV rays have beneficial effects — such as helping the body manufacture adequate amounts of vitamin D. Visible light and blue light Blue light from sunlight is very important in regulating circadian rhythm — our natural wakefulness and sleep cycle. Exposure to blue light from the sun during daytime hours helps maintain a healthy circadian rhythm. Blue light filters and protective eyewear All three are new police officers in their probation period with the PSNI, the odds are at least one of them isn’t going to last. The pressure is immense, but if they succumb to it, they won’t survive. Often the rookie officers don’t know the extent of the peril they are in, or who they can trust. What’s it like to have to hide your job from neighbours, friends and even family? How do you distinguish between who needs your help and who wants you dead simply because of the uniform you wear? Directed by Gilles Bannier (Trigger Point, Tin Star, Spiral) and inspired by extensive research and interviews, Blue Lights is an authentic, gripping and darkly funny drama about ordinary people doing an extraordinary job in a society that could spiral out of control at any moment. Use a different lamp: If you enjoy reading in bed, try a lamp that emits red or orange light rather than blue.

The most effective way to reduce exposure to blue light in the evening is to simply turn off the sources. This means dimming or reducing LED and fluorescent lighting in your home and turning off electronic devices after it gets dark outside.A 2015 review has shown that blue light kills acne-causing bacteria and lowers inflammation in acne breakouts. One important note: If you’re going to try at-home blue light devices, make sure you choose one approved by the Food and Drug Administration (FDA). Help clear some skin conditions It's worth noting that OLED screens – like those used in LG's OLED TVs like the LG CX, or even the Samsung Galaxy S10 smartphone – generally use less blue light than traditional LED lighting technologies too (via FlatPanelsHD).

Try an app: If you need to use devices before bed, try out one of several smartphone and computer applications that can help reduce blue light emission.This is great for keeping you active in the late hours for a big project deadline, or if you’re trying to stay awake, but it’s not as great when you’re trying to sleep. Harvard Health cites numerous medical studies making a strong case for melatonin suppression by blue light – and specifically recommends people “avoid looking at bright screens beginning two to three hours before bed.”
