DayMax (yellow lense) Oscar Glasses - Crystal

As long as you’re working with screens or in artificial lighting, daytime blue light glasses will protect your eyes and health. If you’re out in the sun or not being exposed to any artificial light, however, there’s no need to wear blue light glasses. The sun’s light is beneficial in regulating our body’s natural systems, such as the sleep-wake cycle, body temperature and digestive system. Wearing blue light glasses out in the sun will hinder these natural processes.

Blue light glasses are created to protect our eyes from the damaging wavelengths of artificial light (380nm-550nm) which lies in the range of blue and green light. They are created to protect our eyes from screens and LED lights that release excessive amounts of this wavelength.  Sunlight is beneficial for the body, to regulate our natural cycles. So there’s no benefit to wearing blue light glasses when outside.

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.

The 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!
