What Is a Blue Light Blocking Screen Protector? How Optic+ Filters Blue Light and UV

A blue light blocking screen protector filters some of the blue light coming off a display. ScreenShield calls Optic+ Blue Light Blocking its most innovative range, and it filters light in the blue light range as well as UV light.

It’s available for well over 30,000 devices, from laptops like the Lenovo ThinkPad E16 to e-readers like the Boox Go Colour 7 Gen II. If a model isn’t listed, ScreenShield can custom-make one.

What Is a Blue Light Blocking Screen Protector?

The key part of Optic+ Blue Light Blocking is an optical adjustment layer. This layer filters out light that falls into certain wavelengths, which is how it cuts down the blue light coming from the screen.

According to ScreenShield, the protector significantly reduces the amount of blue light emitted by digital devices and is designed to help protect your eyes from prolonged exposure to it. ScreenShield also notes that the protectors are not a substitute for professional eye care and that individual experiences may vary.

How Does It Block UV?

The same optical adjustment layer blocks ultraviolet light, the type that causes sun damage and fading to items left outside. In ScreenShield’s testing, it blocked an average of 99.8% of UV light.

That figure is mostly about the device. UV radiation from the sun can damage a screen, and the UV blocking helps guard against it.

How Is Blue Light Blocking Different from Nano Glass?

Blue Light Blocking is about filtering light, and Nano Glass is about strength and clarity. Here’s how the two compare.

Glare is a different problem again, and that’s what Optic+ Anti-Glare is for. If you’re mainly after toughness, Nano Glass is the stronger pick, and What Is Nano Glass? covers how it’s put together.

Why Choose Blue Light Blocking?

ScreenShield makes every Optic+ protector itself, so buying from ScreenShield means buying from the manufacturer. Each one is cut for a single device model, and orders go out from Melbourne, where the team works.

Does It Protect Your Screen?

Scratches are covered. The protector was engineered with durability in mind, and its scratch resistance is there to keep the device in pristine condition. The UV blocking also means a screen that spends time in the sun is better protected against UV damage.

Will It Change How the Screen Looks?

Mostly, no. The protector is designed to keep the screen’s clarity and colour accuracy, so the display stays vibrant.

In some light, though, it can pick up a slight yellow tint. ScreenShield says that varies with the environment and fades under normal lighting conditions.

You’ll find it listed for laptops, monitors, tablets, e-readers and phones. A few examples:
