Blue Light Blocking Glasses
Everyone is familiar with the feeling of being over exposed to blue light. For office workers, it can feel like tired or irritated eyes, the digital eye strain brought on by hours focusing on a screen under harsh artificial lighting. For those who like to unwind at the end of the day by gaming or watching a few episodes of their favourite show, it can feel like the strange restlessness that doesn’t let you get to sleep.read more
You can combat these problems by reducing your cumulative blue light exposure with the use of BlockBlueLight glasses. Our range features products designed to filter and moderate blue light exposure during the day with our daytime computer blue light filter glasses , and eliminate the risks of blue light exposure in the evenings and night-time with our premium 100% blue and green light blocking glasses.

Filters 50% Blue Light
Minimal Colour Distortion
Reduce Digital Eye Strain
Less Headaches & Eye Fatigue
The ScreenTime Computer Glasses range are specifically designed to permit the good light responsible for alertness, mood, brain activity, and optimal health, whilst filtering the harmful artificial blue light that leads to digital eye strain, headaches, and macular degeneration. Our unique filtering technology reduces blue light by 50% across the entire blue light spectrum,read more
but more specifically, it targets blue light at the 455nm range and filters it by 50%; this is an important feature to look for when selecting a pair of computer glasses, as the strongest wavelength of light emitted from digital devices and LED lighting is exactly at 455nm.
When it comes to blue light glasses for computer use that are on the market, if no details are provided about the exact wavelengths being filtered, it’s more than likely the computer glasses will not provide adequate blue light protection for daytime use. The ScreenTime glasses are perfect for people who require a clear lens with no colour alternation or distortion or are in often in social and office environments during the day.
DayMax Light Sensitivity Glasses (Yellow Lens)
Great For Boosting Mood
Reduce Headaches & Migraines
Assist With Light Sensitivity
Maximum Daytime Protection
The DayMax Glasses range provide the next level up on the screentime computer glasses and give maximum protection against blue light during the daytime. These can often be described as light sensitivity glasses, gaming glasses, or mood bosting glasses. The light yellow DayMax lenses use propriety filtering technology to specifically target and to block 100% of blue light in the lower range of the spectrum at 400 – 455nm;read more
this is the most energetic and damaging light emitted from screens and modern lighting. The DayMax lens will still allow all the beneficial blue light through still which is in the higher part of the blue light spectrum from 455 - 500nm, this is the blue light that is essential during the day for optimal hormone production, energy, positive mood, and motivation. The DayMax is ideal for people who are light sensitive, on screens all day, regularly suffer from migraines and eye strain, or are prone to anxiety, depression, or low mood. These symptoms indicate the need greater protection against artificial blue light than our ScreenTime computer glasses can provide.
SunDown Blue Blocking Glasses (Amber Lens)
Lower Stress & Anxiety
Lighter Amber Lens
Blocks 100% Of Blue Light
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.
NightFall Blue Blocking Glasses (Red Lens)
Most Optimal Night-time Glasses
Aligns With Academic Studies
Maximise Sleep Quality
Blocks Blue & Green Light
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.
ScreenTime Clear Lens - These filter 50% of blue light across all of the blue light spectrum (400nm-500nm), this will help eliminate digital eye strain, sore and tired eyes, headaches/migraines, and blurred vision from both screen time and bright LED or fluorescent lighting.
More specifically they filter 50% of blue light right at 455 nanometers which is the most energetic, damaging light emitted from screens, LEDs, and other modern artificial lighting. By filtering 50% of blue light at 455nm makes our ScreenTime Computer Glasses the most effective clear lens computer glasses available
DayMax Yellow Lens - These filter 70% of blue light across all of the blue light spectrum (400nm-500nm), these provide maximum daytime protection and are prefect for people who are light sensitive or are on screens most of the day or under harsh artificial lighting all day.
More specifically they block 100% of blue light in the lower range of the spectrum at 400 – 455nm; this is the most energetic and damaging light emitted from screens and modern lighting. More importantly they still allow all the beneficial blue light through which is in the higher part of the blue light spectrum from 455 - 500nm, this light is essential for maintaining high energy, positive mood, and motivation.
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.
The lighter amber tint allows for greater colour perception in the evening hours for a more pleasant viewing experience. These are a great option to use in the early evening while cooking dinner, watching TV, or out socialising.
Clear or yellow lenses are not sufficient for night use! - Any blue light lens that is clear or yellow will not be sufficient for night-time use. These types of lenses do not block enough of the blue light wavelengths to have positive impact on sleep and circadian rhythms. Even just a small amount of blue after dark will signal to the brain that it’s still daytime which in turn will suppress our sleep hormone melatonin from being released. This is why it’s extremely important to use a set of blue light glasses that have been verified to remove 100% of all the blue wavelengths or they will not be very effective at all.
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.
This harmful blue and green light has been extensively researched, and has been proven to inhibit our body's ability to naturally produce melatonin, the brain's 'sleep hormone'.
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.
Our ScreenTime Computer Glasses filter 50% light ranging from 400 to 500 nanometers. What sets ours glasses apart from all the other computer glasses is our ClearBlue lens technology; this filters 50% of blue light at 455 nanometers, this is where the most energetic, damaging light emitted from screens, LED’s, and other modern artificial lighting; Most companies supplying clear blue blocking glasses are only blocking 5% - 15% of blue light and are not blocking any at the 455nm range where it matters the most!
We have specially designed our clear lenses in a unique way that the most harmful wave lengths of blue light are blocked which causes eye strain, headaches, migraines, and macular degeneration, and at the same time still providing crystal clear vision without any color distortion
We also have our DayMax Glasses range which provide even greater daytime protection. These have a light-yellow tint and block 100% of the harmful blue light emitted from screens and lighting, while still allowing the beneficial natural blue light through we need for energy and mood.
Our daytime blue light computer glasses are very different to the add on blue light filter offered by optometrists to put on your prescription lenses. Our ScreenTime clear lens glasses filter blue light by 50% across the whole blue light spectrum and specifically target blue light at 455nm, and for greater protection or DayMax yellow lens completely blocks 100% of the damaging 455nm blue light spike, this is the peak wavelength of blue light emitted from screens and lighting, there is not many blue light glasses for daytime use on the market that do that.
Most computers glasses and coatings applied to prescription lenses filter blue light up to 430nm and none at 455nm so they are pretty useless! The problem with the filter on the prescription lenses if you ask the optometrist the specs of the filter they wouldn’t have a clue, they just call its a generic “blue light filter” with no details at all! I can guarantee you these won't be filtering any blue light past 430nm, as to filter past 430nm you need a pigment embedded in the lens to absorb the blue light, the coating they apply just reflects blue light and that type of coating cant reflect blue light past 430nm.
Not all blue light glasses are created equal so do your research before buying some to ensure they provide adequate protection.
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.
Alternatively we have created our fit-over range of daytime blue light computer glasses which have been specifically designed for this reason. This allows you to put our lightweight fit-over glasses over the top of your glasses to provide you with the best blue light protection. You can continue to wear your existing reading or prescription glasses, and our fit-over glasses will nicely fit over them and provide maximum protection against blue light.
Daytime glasses will not be effective for use at night-time and will not provide any benefits for sleep. To be effective and help with sleep, night-time blue blocking glasses MUST block 100% of blue light, or even better would be 100% of blue and green light up to 550nm. This is because any amount of blue light at night is a signal to the brain that its daytime and the sun is up. Daytime glasses don’t block all blue light, they are only designed to filter it down to more natural daytime levels.
If you’re wanting to allow yourself to truly wind down and relax in the evening and then get deep and restful sleep, a pair of night-time blue blocking glasses is essential
We do not recommend using the night-time glasses during the day as this will create a circadian mismatch and will actually cause issues with sleep later in the evening. Using night-time glasses during the day with be very harmful and will actually be detrimental to your health. Let me give you a bit more detail as to why:
Our night-time glasses block 100% of blue light, and when your brain receives no blue light signals it assumes its night-time so it will start to prepare you for sleep even if it’s the middle of the day. So having these glasses on during the daytime will leave you feeling tired, unmotivated, sleepy, and your brain will be very confused as to what’s going on!
Overtime a lack of blue light during the day will lead to depression, anxiety, and low mood, so you want to make sure you’re not blocking it all out during the day!
We need healthy amounts of blue light during the day as its responsible for making us feel awake, motivated and alert. The issue we have is we get far too much blue light during the day as modern lighting, screens, and devices, as they emit very unnatural levels of blue light, so we need to bring it back into balance and that’s were our daytime glasses help.
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!
So be sure to look for the exact specifications of blue light filtering when getting daytime glasses.
Then at night-time we need to make sure we block ALL blue light, as any amount getting through is enough of a signal to the brain that it’s still daytime, so our sleep hormone melatonin will be suppressed and you will have lower sleep quality, trouble falling asleep, or staying asleep, or all of these issues. So ensuring the glasses you use are blocking 100% of blue light is key for night-time!
