Red Clip-on Blue Blocking Glasses

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.

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.
