As an optometrist, I couldn’t help but notice EyeJust — between its catchy name, eye-themed logo, and claim to protect your eyes from harmful blue light, I was intrigued. The company has been featured in various magazines and all over social media.
We live in a Digital Age, where the average American spends approximately nine hours a day in front of a screen. Research has shown that overexposure to blue light is linked to digital eye strain (aka computer vision syndrome). This is an eye condition that includes symptoms of blurry vision, eye strain, fatigue, and headaches. With our increasing reliance on digital devices, it is important to protect our eyes from harmful blue light.
However, with so many different blue light blocking products on the market, what does EyeJust actually do? Below is a complete review of what you need to know about EyeJust blue light blocking screen protectors, including the pros and cons of this tech-friendly accessory.
What is EyeJust?
EyeJust is a screen protector for digital devices (iPhone and iPad). It’s designed “to combat the negative effects of blue light emitted from digital devices in order to prevent eye damage, sleep disruption, and premature aging of the skin.”
What is blue light? Why is it a concern?
Blue light is part of the electromagnetic spectrum that is visible to the human eye. As it is the highest energy wavelength visible, it is sometimes referred to as HEV light (High-Energy Visible light).
HEV light can pass through the cornea and lens of your eye. As a result, it can reach the retina and damage the photoreceptor cells (rods and cones).
Research has shown that blue light can disrupt natural sleep cycles by suppressing melatonin production — a hormone that influences circadian rhythms. It has also been linked to premature aging and pigmentation of the skin.
Common sources of blue light include digital devices (mobile phones, tablets, and computers), artificial indoor lighting, and the sun. While the highest concentration of blue light comes from the sun, nowadays, the average American spends more time indoors. Our increased reliability and use of digital devices has drastically increased the amount of blue light reaching our eyes on a daily basis.
There are a number of ways you can protect yourself from blue light, including but not limited to: blue light filters in eyeglass lenses, Apple Night Shift mode, and reducing screen time. Depending on what you do for a living, limiting your screen time may not be an option. Fortunately, this is where EyeJust comes in! The product cuts the amount of blue light you are exposed to at the source.
EyeJust’s patent-pending technology blocks blue light without changing the look or color of the screen, as tested by the Gavin Herbert Eye Institute at UC Irvine. It also protects your devices with crystal-clear, scratch-proof, optical-grade tempered glass.
Due to its anti-microbial and oil-resistant design, EyeJust products are germ-free and smudge-proof.
How much blue light does EyeJust block?
EyeJust screen protectors block 50 percent of blue light (HEV), specifically between 440nm and 460nm on the visible light spectrum.
By targeting this range, EyeJust protects your eyes and skin from blue light without changing the color of your phone screen.
How is EyeJust different than Night Shift on iPhone?
Apple Night Shift is an option on your iPhone that “automatically adjusts the colors of your display to the warmer end of the spectrum,” theoretically reducing the amount of blue light your iPhone is emitting. By default, it is activated between sunset and sunrise to reduce the sleep disturbance caused by late-night browsing on your phone. In the morning, however, the display returns to its regular color temperature settings. This means your eyes are not being protected from blue light during the daytime when most of us are on our phones anyways.
EyeJust screen protectors help during the hours Night Shift isn’t activated. Also, when combined with Night Shift, the product is thought to help block an even higher percentage of blue light.
How much does EyeJust cost?
- Eligible devices: iPhone 6/6s/7/8, 6+/7+/8+, X/XS, XR, XS MAX
- Eligible devices: iPad Mini, iPad 9.7″
Is EyeJust right for you?
- Protects your eyes and skin from harmful blue light.
- Unlike Night Shift mode or some blue light blocking glasses, EyeJust does not have a yellow tint or change your color perception.
- It is made from anti-microbial, smudge-proof, tempered glass.
- It comes with a 2-year guarantee and replacement warranty.
- It doesn’t protect you from all sources of blue light (e.g. computer, artificial lighting, and the sun).
- It doesn’t cover the full range of blue light (380nm to 500nm), only a targeted range (440nm to 460nm).
- Only available for select Apple products (iPhone and iPad).
Overall, I would recommend this screen protector to anyone who spends a lot of time on digital devices and wants to try out a blue light blocking product before spending money on a pair of blue light blocking glasses. As someone who uses a tempered glass screen protector anyways, it’s reassuring to know that by upgrading to an EyeJust screen protector, I’ll still be protecting my phone — and my eyes from blue light — without sacrificing the color or clarity of my display. It’s an easy switch, with added eye health benefits.
However, this screen protector isn’t a one-size-fits-all solution for digital eye strain simply because it doesn’t offer protection from all sources of blue light, only from smartphones and tablets. Another drawback is the company’s limited product availability. To fit the needs of a larger population of tech-users, it would be practical to offer screen protectors for non-Apple smartphones and tablets, as well as computers and laptops.
Ultimately, I think the best way to protect your eyes from blue light is by limiting your screen time and by investing in a high-quality pair of eyeglass lenses that offer blue light protection (such as Crizal Prevencia or Transitions Lenses). That way, you are correcting your vision while also protecting your eyes from all known sources of blue light, during the day or night, both indoors and out.
