Blue Light Blocking Glasses

Digital screens, fluorescent lights, LEDs, and even TVs emit a type of light – blue light – that we know can be harmful. A small part of the visible spectrum of light, blue light is disruptive to sleep cycles, contributes to eyestrain, and is potentially damaging to the retina. Digital protection glasses block blue light, protecting against macular degeneration and the many other issues associated with exposure to blue light.

In the visible spectrum of light, blue light is included in the high energy visible (HEV) light range, which is known to be damaging to our eyes. Blue light makes your eyes work harder, which is why people who spend long hours in front of screens often complain of eyestrain and headaches. In addition to overworking the eyes, blue light can cause premature macular degeneration. Protecting your eyes from blue light may help to ease your eyestrain and preserve your vision.

Reducing blue light exposure has been clinically proven to increase nighttime melatonin levels, which can lead to higher-quality sleep. While there are few clinical studies on the long term effects of blue light on the retina, countless reports from wearers of blue light blocking glasses report reduced eye strain, less headaches, and improved sleep.

Because blue light blocking glasses only filter out blue light, they are fine to be worn all day long. Some people have expressed concerns about how blocking natural blue light could reduce melatonin production and contribute to sleep problems, but this is simply not an issue. Blue light blocking glasses still let in some blue light, more than enough to stimulate melatonin production. Many wearers of digital protection glasses love the way they look and never want to take them off– and it’s perfectly safe not to.

Yes and no. There is a misconception that all blue light glasses help with night driving. This idea stems from the fact that the old style of blue-light glasses (with visibly yellow lenses) contributed to clearer night vision. The newer style of blue light glasses feature much clearer, less yellow lenses and do little to help with night driving. To help with night driving, you’ll be better off wearing glasses with an anti-glare coating.

No, blue light blocking glasses can not damage your eyes, even when worn all day long. Blue light glasses are designed to work by filtering out a very narrow part of the visible spectrum of light– blue light that causes eye strain and may contribute to macular degeneration. Blue light glasses protect your eyes and can’t cause them any harm.

Some individuals are very sensitive to blue light from screens. These light-sensitive types who work on a screen all day may come to consider regular headaches an occupational hazard. However, wearing blue- light glasses can help to ease the symptoms of eye strain, including headaches. Many wearers of blue-light glasses report relief from headaches immediately when they begin wearing their glasses. Digital protection glasses can reduce both the severity and frequency of headaches caused by blue light.

You should wear blue light glasses whenever you are working at a computer, on a tablet, or reading on a phone. TV addicts who spend long hours watching films and shows also benefit from wearing blue light glasses. Fluorescent lights and LEDs emit blue light as well, and if you spend many hours in such lighting, wearing blue light glasses may help protect your eyes. In fact, even though the best time to wear blue light glasses is in the evening– to improve sleep cycles– wearing them throughout the day is completely fine.

In the early days of blue light glasses, the lenses were a distinct yellow, and the frames were notoriously uncool. However, these days, blue light glasses are super-stylish and designed to only filter out blue light at the higher end of the spectrum. The lenses are not noticeably yellow at all. So, while they are imperceptibly yellow (and have to be in order to work), no one will ever know, unless you tell them.

Generally speaking, you should look for the same things you look for in any pair of glasses. Start by choosing frames that are the right size for your face shape. Then, find a pair of blue light blocking glasses that match your personal style. If you need reading glasses, consider a pair of glasses with SightRelax lenses. If you wear prescription glasses, you can just add a blue light blocking feature to your prescription at checkout.

There are a few ways you should be able to tell if blue light glasses are working. At the end of a long day of heavy screen use, you can note whether your eyes feel less dry, are less bloodshot and feel less strained. If you suffer from frequent headaches, if they decrease in frequency and severity, you’ll know that your blue light blocking glasses are working. Your sleep cycles should improve with wearing blue light glasses–it should be easier to fall asleep and stay asleep.

Blue light blocking glasses with clear lenses can block between 5% and 40% of the harmful blue light spectrum. Anything above that requires visibly yellow lenses. The good news is that you don’t need to block more than that to experience a notable improvement in sleep and reduction of eyestrain.

As a part of the visible spectrum of light, blue light is present in many different settings. Fluorescent lights, LED lighting, and yes, even the TV screen, emit blue light. Even the sun emits blue light. Blue light is primarily harmful when it is emitted close to the eyes as it is with digital device use. Blue light exposure at night is disruptive to natural sleep cycles. Wearing blue light glasses while watching TV can help to reduce exposure.

Only if you need a prescription normally. If you don’t need prescription glasses to begin with, you don’t need a prescription for computer glasses. Blue light blocking glasses, also known as computer glasses, come in nonprescription and prescription lenses. Our SightRelax glasses offer a section of the lens designed for reading – giving you the best of both worlds.

If you spend a lot of time in front of screens – computer screens, tablets, or even just reading on your phone – you may have noticed some negative effects. If you have trouble falling or staying asleep, frequent headaches, or experience eye strain after a long day staring at screens, you may need computer glasses.

At first glance, you can’t tell that your glasses are blue light blocking. They have such a minimal yellow tint that it isn’t perceptible. You may be able to detect a very slight warmth when comparing a white section of a digital screen with the glasses on compared to when they are off. When light is reflected off of blue-light glasses, it may have a slightly rosy tint visible to others. The only way to be sure that your glasses are blue light blocking is to order them specifically.

While the clinical research about blue light and skin damage is ongoing, we know that digital blue light exposure causes more pigment damage, redness, and swelling than blue light from the sun’s rays. Blue light may stimulate free radical production in the skin, accelerating the formation of wrinkles and other skin problems. While all of this is bad news for those who spend long hours at a computer each day, it’s yet another reason to wear blue light blocking glasses. The delicate skin around the eyes is one of the first areas to show signs of skin damage, and protecting the eye area from blue light can help to slow this process down.

While digital technology and LED lighting have not been around long enough for us to know definitively what their long-term effects are on aging, what we do know is not good news. Some studies have shown that blue light accelerates the aging process of cells beyond the eyes and skin. Part of this is due to interruptions in circadian rhythms, which can affect brain wave activity, hormone production, and cell regeneration. The key takeaway is that reducing the number of hours you are exposed to blue light is a good idea. Wearing digital protection glasses is a good first step, but using settings that reduce blue light exposure in the evening is also a wise measure to take.

Eye doctors often recommend computer glasses to patients whose intermediate distance vision is becoming less clear, or if screen usage results in eye strain and headaches When eye strain and headaches become common a sore neck and sore shoulders can become a problem from leaning forward to focus on the screen. While there is limited clinical evidence for computer glasses resolving some of these issues, scores of glasses wearers report improvement with computer glasses.
