We’ve all had those nights where we’re working on a laptop or scrolling through our phone before glancing at the time to find it’s actually a lot later than we thought. Most nights, you’d be fast asleep or at least dead tired at midnight or 1 or 3 a.m. But after staring at a screen, you’re somehow just as awake as during the heart of your day.

That’s probably not a coincidence. Circadian rhythms drive your internal body urges to wake up each morning and start getting tired each night. That process is spearheaded by the hormone melatonin, which your body creates during the night. But researchers believe blue light like the kind emitted from laptop, tablet and smartphone screens confuse that process, acting as a melatonin suppressor that throws off your body’s internal mechanisms and can potentially mess with sleep patterns.

The Ocushield Anti-Blue Light Screen Protector was created to cut down on those blue light emissions, their detrimental effect on your sleep as well as the impacts of blue light exposure, including headaches, eye irritation, fatigue and more.

The Ocushield is a super-strong tempered glass screen that can block up to 90 percent of all harmful blue light from your retinas. The screen is removable and coated with a scratch-resistant oleophobic layer that assures its durability and better protects your device from the rigors of daily life.

Created by a team of optometrists, eye care experts and sleep therapists, the Ocushield is officially recognized as a MHRA Class 1 Medical Device, the world’s first and only medical rating for blue light screen protection. Read the rest
