Blue Light Filter Glasses

By staring at screens all day, we're also exposed to blue light waves, which are said to cause a myriad of issues. There is conflicting evidence about how blue light exposure affects your eyes, but doctors and researches are in agreement that it does affect your circadian rhythm. More on that below.

Before the advent of artificial light, the sun regulated our sleep schedules. But today, we're exposed to light all day and into the night. While exposure to any light waves after dark delays our bodies' production of melatonin, blue light waves can be especially problematic because they keep us alert.

Talking to CNET, Dr. Raj Maturi, a clinical spokesperson for the American Academy of Ophthalmology, explained, "During the day, you get 10 times as much blue light from the sun as you do from your computer screen. Our bodies have evolved to deal with this light."

However, research compiled by the AOA indicates that prolonged exposure to blue light (such as sitting in front of a computer all day) might cause damage to your retina -- the innermost layer of your eye that sends signals to your brain to process what you are seeing.

Blue light blocking glasses have filters in their lenses that block or absorb blue light, and in some cases UV light, from getting through. That means if you use these glasses when looking at a screen, especially after dark, they can help reduce exposure to blue light waves that can keep you awake.

As for me, I'm writing this article wearing a pair of blue light blocking glasses that I've used off and on for the last few months. While I'm not 100% certain that they are helping my eyes, I do notice my eyes feel less tired at the end of the day.

Our blue light filtering glasses are designed to protect your eyes from UV and preserve visual comfort by filtering blue-violet light*. Blue-violet light might accelerate the aging of the retina. It is one of the risk factors for age-related macular degeneration (AMD), among others like genetic and environmental factors such as smoking and diet. Our various optical solutions filter blue-violet light* while allowing blue turquoise light, which is essential to your health, to pass through.

In the early days, the lenses of blue light glasses were yellow, and the frames were notoriously uncool. But these days, they are super stylish and designed with seemingly clear lenses that filter out blue light at the higher end of the spectrum. So, while the lenses 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 right for your face shape. Then add blue light filtering lenses to your frame of choice.

Our blue light filtering glasses are effective at reducing your blue light exposure between 415 nm and 455 nm. This exposure comes from long hours spent in front of electronic devices like laptops, smart phones, and televisions.

Once the sun sets, even minimal exposure to blue light will cause suppression of melatonin, increase in stress levels, and circadian rhythm disruption. We have designed our SunDown and NightFall ranges of blue light lenses specifically for night-time use to lower stress hormones and improve sleep quality.

The SunDown range are designed and verified to block 100% of blue light. Using these glasses in the evening will increase melatonin levels and sleep quality. These are best worn 2-3 hours before bed for optimal results. The amber lens is an ideal option for people who are wanting a high quality premium 100% blue blocking lens, but prefer a lighter amber tint over the red lens to allow more colour perception in the evening hours.

The NightFall range is the most powerful and premium lens available. These block 100% of blue light along with 100% of green light up to 550nm. Why green light? Well, green light is right next to blue on the visible light spectrum, and the melatonin disruption zone extends right into the green light spectrum. These glasses provide the most optimal blue (and green) light protection available to maximise sleep quality. The red lens is the best option for people struggling with poor sleep or insomnia, or are looking to maximise sleep quality as much as possible.

BlockBlueLight's night-time sleep glasses have been specifically designed to block ALL the blue and green light wavelengths which are emitted from electronic devices and any artificial light sources. This includes smartphones, laptops, computer screens, LED and Plasma TVs, tablets, fluorescent lighting in offices and stores, and conventional LED lighting in homes.

When worn after the sun goes down, our night-time glasses block out ALL blue and green light, allowing your body to naturally wind down and prepare for sleep. This ensures you will fall asleep fast, stay sleep longer, and guarantees quality restful sleep.

BlockBlueLight's night-time sleep glasses give you the best of both worlds: you can still use phones, devices, tablets and watch your favourite TV shows, yet your sleep and health don't need to suffer. By effectively blocking blue and green light from a variety of sources you allow maximum melatonin production to occur, helping you to get the best night's sleep, and wake up full of energy.

NightFall Red Lenses - These block all light wavelengths of blue and green light up to 550nm. These are the exact wavelengths shown to most affect our internal clock, lower melatonin levels alter our sleep/wake cycle.

The NightFall Red Lenses not only block 100% of blue light but also all green light up to 550nm. Why block green light as well? Research and academic studies clearly show the green light emitted by modern electronic devices and light bulbs is also contributing to suppressing melatonin levels at night.

SunDown Amber Lens - The SunDown Amber lenses are an ideal option for people who are wanting a high quality premium blue blocking lens verified to block 100% of blue light, but prefer a lighter amber tint over our nightfall red lens.

All of BlockBlueLight's night-time glasses have been extensively researched, scientifically designed and manufactured specifically using the best technology to ensure ALL of the wavelengths of harmful blue and green light are both being removed. Our glasses block blue and green light in line with peer reviewed academic literature.

A lot of the orange or red-tinted blue light glasses being sold are just simply that, red and orange-tinted glasses. Often suppliers have not properly designed the lens to ensure it is actually blocking the correct wavelengths of blue light, with no research or testing in these products' development. If this is the case, you aren't likely to notice any significant changes or benefits from these types of lenses.

There are also many other brands of blue light glasses are being sold that have clear lenses yet are still claiming to block various sources of blue light. Typically, these lenses are really only filtering out very small amounts of blue light. Common clear lens blue light glasses will only really be capable of filtering around 10% - 20% of blue light - slightly beneficial for eye strain but they will not have any benefits in preserving melatonin and improving quality of sleep.

We have our lenses tested by a laboratory grade spectrometer to ensure we are producing the very best lenses which effectively block all blue light. You can see our lens testing reports here. We are confident that you won't find better quality blue light blocking glasses on the market.

Many glasses that claim to be blue light blocking glasses on the market are just cheap glasses with an insufficient blue light reflective coating applied to them. These cheap glasses only filter anywhere from 5-15% of blue light. No science has gone into creation of blue light lens to ensure its blocking blue light in line with peer reviewed academic literature for sufficient protection.

BlockBlueLight's Blue Light Glasses are evidence based, science backed, and align with the academic research on blue light. We use a special pigment embedded into the lens which absorbs the blue light as it passes through (instead of just a basic reflective coating), this ensures our blue light lenses block 100% of all the blue and green light up to 550nm which is the exact wavelengths of light shown in the research to lower our melatonin levels and impact our sleep.

BlockBlueLight Glasses are also made with top quality acetate frames with spring hinges and top of the line optical grade CR-39 lenses . We are confident that you won't find better quality blue light blocking glasses on the market.

Our daytime glasses allow the healthy wavelengths of blue light through to allow you to feel awake and alert, and filter down the harmful wavelengths that cause eye damage, headaches, and eye strain.

The key here is to target the exact wavelengths of blue light that lighting and screens emit the most, this is 455nm. Our glasses have been designed to filter the 455nm range of blue light by 50% with our ScreenTime clear lens, and 100% with our DayMax yellow lens, whereas most daytime blue light glasses will only filter blue light up to 430nm, and filter none at all at 455nm making them very ineffective!

These glasses should stay on from the point of sunset up until going to bed. This allows your brain to recognise that its night-time and to start to wind down for sleep, this cannot happen in the presence of any blue or green light.

Yes, we have our complete glasses range available in prescription glasses and readers glasses. We can make any custom prescription including progressive/varifocal lenses. On each glasses product page, there is a selector to choose prescription glasses, you then choose if you want single vision or progressive/multifocal lenses and whether you would like standard lenses or thin and light lenses. There is then a place for you to upload your script as well. Then checkout and place your order. From here our optics lab will take care of the rest getting you custom prescription glasses made for you. 2351a5e196
