SHINU Launches Day-Night Blue Light Protection Combo
SHINU Launches Day-Night Blue Light Protection Combo
We are excited to introduce our brand-new day-night blue light protection combo.
Many people rely on a single blue light filter for all hours of the day, but this approach has a clear limitation: no single filter works equally well for daytime and nighttime use.
Here is the science behind this design. The 460–480 nm blue light band plays a key role in regulating our circadian rhythm. During the day, this wavelength helps keep us alert, supports focus and maintains our natural body clock. It is beneficial for us when exposed under natural daylight or screens.
After sunset, however, this exact 460–480 nm blue light becomes disruptive. It strongly suppresses melatonin production, making it harder to fall asleep and reducing sleep quality. Wavelengths from 480–570 nm also carry weaker circadian effects; our sensitivity drops gradually as the wavelength gets longer.
For people living with photophobia, the 480–520 nm range is a common trigger for eye discomfort. Special filters are needed to ease this light sensitivity while staying usable in daytime.
That is why we built this day-night series. Our daytime filters preserve the helpful blue light signal your body needs, while cutting excess harsh light and unwanted screen glare. They keep your vision natural and balanced for work, study and screen time.
Our nighttime filters block the sleep-disrupting blue light bands. They help your body produce melatonin normally, so you can wind down better after dark. We offer different nighttime grades to match different levels of sleep support you need.
There is no universal filter. What protects your sleep at night will take away the beneficial light your body needs in the day. What works comfortably for daytime screen use cannot fully shield you from rhythm-breaking blue light after sunset.
Our SHINU day-night combo lets you pick the right filter for the right moment. Choose the combination that matches your lifestyle: regular screen use, mild or moderate light sensitivity, and your sleep goals.
