Blue light, like other visible light hues, is all around you. Blue light is emitted by the sun. Fluorescent and incandescent light bulbs are also affected. Because to the growing use of light-emitting diode (LED) technology, humans are being exposed to more blue light than ever before.
Blue light from digital devices like smartphones, tablets, computers, and televisions is linked to eye health problems such as computer vision syndrome (CVS), eyestrain, and dry eyes.
Wearing glasses that block blue light can help reduce the symptoms associated with CVS, such as blurred vision and eye strain. They can also prevent macular degeneration and cataracts, two common causes of blindness.
Prevents Macular Degeneration
Blue light is a higher energy component of the visible spectrum that can penetrate your eye and damage the retina, causing age-related macular degeneration (AMD) to develop. This condition affects the macula, a small region in the back of your eye responsible for central vision.
While exposure to ultraviolet rays from the sun is considered the most harmful, electronic devices emit a significant amount of blue light, too. It can lead to several severe eye conditions, including cataracts and macular degeneration.
There is evidence that too much blue light may increase your risk of developing AMD, although it’s still unclear how safe and practical exposure is. Research has also shown that too much blue light before bedtime can interfere with our bodies sleep cycle, disrupting melatonin production and affecting our circadian rhythm.
Fortunately, there are several options for protecting your eyes from the detrimental effects of blue light generated by digital devices. One way is to use a pair of blue light glasses designed to filter out the high-energy blue light emitted by electronic devices and screen lighting.
Blue light glasses benefits include the relief from digital eyestrain symptoms and improved sleep by blocking blue light from the sun, screens, and mobile phones.
Reduces Eye Strain
Various screens emit blue light, including computers, phones, and televisions. If not avoided, it can cause various eye symptoms, such as fatigue, blurred vision, and headaches.
The best way to reduce digital eye strain is to practice good screen habits like looking away from the screen every 20 minutes, adjusting the lighting in your workspace, and using artificial tears if your eyes feel dry.
Several options are available if you decide to invest in a pair of blue light glasses.
While there is little evidence that blue light glasses can help reduce digital eye strain, they may be helpful for people who have insomnia caused by late-night screens. Several studies have found that blue light disrupts our sleep cycles by influencing our natural circadian rhythm.
Blue light glasses, available at drugstores and online, block some of the rays of light emitted by smartphones, tablets, and computers. They may also protect your eyes from the damage caused by overexposure to blue light, which can contribute to cataracts and age-related macular degeneration.
Blue light has been shown to increase the rate of eye damage caused by oxidative stress, a risk factor for developing cataracts and macular degeneration. However, studies have not yet demonstrated that blocking blue light can prevent these eye conditions.
The good news is that most people’s exposure to blue light comes from natural sources, like the sun. Even so, knowing how much time spent on digital devices can lead to eye damage is essential.
If you are worried about the effects of blue light on your eyes, talk to an eye care professional before making any decisions. They can suggest protective measures to reduce exposure to blue light, including filters for your screen and computer glasses with yellow-tinted lenses that block blue light.
Prevents Dry Eyes
Dry eyes are a common condition caused by many things, including allergies or meibomian gland dysfunction. However, the underlying cause of dry eyes can often be treated with a few simple measures.
A humidifier is one of the most effective measures to prevent dry eyes. Not only will it hydrate your skin and hair, but it will also lubricate the eye and ease irritation.
Another way to avoid dry eyes is to avoid gazing at a screen for lengthy periods. Using screens before bedtime is also not recommended, as it can disrupt the body’s natural circadian rhythm and interfere with melatonin production. This hormone helps you fall asleep.
Digital devices like smartphones, computers, and tablets emit high-energy blue light. It is a type of light with a very short wavelength (between 415 and 455 nanometers) that can cause damage to the retina.
While some blue light can benefit your brain, too much exposure can adversely affect your eyes. It can cause dry eyes and other visual problems, such as macular degeneration or cataracts.
If you have dry eyes, consider investing in a pair of blue light glasses. These glasses can help reduce the symptoms of dry eyes by filtering out some of the damaging blue light emitted by your devices. First, however, you should visit your doctor about the underlying reason for your dry eyes.
