Can blue light hurt your eyes?

These changes observed in experimental conditions resemble those due to macular degeneration, which can lead to permanent vision loss. The very best sunglasses should offer full UV protection, however they should also fit your style.

• We live and work in the digital age and spend hours upon hours every week staring into our screens.
• It happens whenever a structure in the back of your eye, the macula, becomes damaged as you obtain older.
• This Harvard article is interesting because I have heard different.
• All of this exposure is particularly dangerous for children.
• Some cones are more sensitive to red, some to green, and some to blue.

Additional research is required to determine if there’s any merit to the claim of IOL blue light protection. An easy way to greatly help limit contact with digital blue light is through the use of a particular screen filter to the front of the device. Screen filters are inexpensive and absorb a lot of the blue light emitted from digital devices, decreasing exposure.

in 2015. That said, there are an increasing level of studies that are suggesting links between blue light exposure and long-term eye damage. Now we regularly spend long periods of time in front of and near screens. As a result, the consequences of blue light are becoming an important health concern. Blue light has more energy per photon than other colors in the visible spectrum such as orange or red. The higher vitality means it has more chance of causing damage to cells, specially the more sensitive cells in our eyes. Some recent, laboratory studies show that there is a chance that blue light affects light-sensitive cells in your retina .
In line with the American Academy of Opthalmology , there is no credible scientific evidence that the light from digital screens is harmful. Therefore, the AAO does not recommend people use blue light glasses.

• This blue light is unlikely to pose a physical hazard
• It signals your brain to wake up when it should be winding down.
• There has been some buzz round the notion that one IOLs are capable of filtering out blue light, however the jury is split.
• The screens of modern electronic devices depend on LED technology.
• This is due to the deterioration of the center of your retina, that is essential for focusing.

Blue light is a visible light spectrum with the shortest wavelength and highest energy. Exposure to blue light affects the sleep-and-wake cycle, or circadian rhythm, by altering the formation of melatonin in the mind. To address indoor blue light exposure, many companies market blue-blocking glasses that filter blue light. One fear is that overexposure to blue light may lead to retinal damage, as occurs in the development of age-related macular degeneration , an eye disease that can blur your central vision.
Causing eye strain and dry eyes, says Rahul Khurana, MD, a spokesperson for the American Academy of Ophthalmology. The good news is eye strain does not cause lasting damage and is easily preventable. By blocking blue light at night, you can prevent the disruption in the natural sleep-wake cycle due to artificial lighting and electronics.

July Is Dry Eye Awareness Month

However, we also need blue light to survive, so enjoying periods in the sun is essential to really get your daily dose. When using your cellular phone, tablet, computer or other digital device, wear computer glasses that have a particular blue light filter coating.

Children should be FORCED to wear eyewear that filters blue light, as there is a possible link to increased rates of myopia, from the over accommodation induced by blue light. In extremely condensed terms, blue light is really a form of high energy light on the visible light spectrum. While the most common source of blue light is provided from the sun, indoor technology such as for example computers, flat screen tvs, and handheld devices emit it aswell. Early research shows that excess blue light exposure can increase the threat of eye diseases, such as for example retinal damage and macular degeneration. Your retina and the center of your retina help you see clearly.

An in vivo study on animals showed damage to the retina and macula due to blue light. So, in humans, blue light could cause permanent vision problems. However, some experts think that more research is needed, especially on humans, to confirm these findings.
But, you have a tendency to look at blue light through gadgets much closer and for longer lengths of time. Blue light filters are screen filters designed for most computers, tablets and phones.
