RetinaGuard iPhone X XR XS Tempered Glass Blue Light Filter Review & Installation Guide

There are many blue light filter screen protectors for Apple products on the market, but which company makes the best overall product? At SleepXP we know from experience what makes a product superior:

  • Quality materials
  • Proven blue light filtering
  • Good quality control
  • SGS & Intertek Certified
  • Optimal balance between blue light blockage & color precision

RetinaGuard meets all those qualities and has the experience to prove it. In fact, the author of this article has preferred RetinaGuard blue light filters over all other brands, as seen by recent Amazon purchase history:

RetinaGuard has been around since 2013 and has focused on making blue light filters for mobile devices, monitors, and computers. If you have an iPhone, iPad, iMac, or Macbook, they have you covered.

Unlike other brands, RetinaGuard's blue light filters aren't a small segment of a larger product line but their entire focus. Industry certifications like SGS & Intertek show they are serious about blocking blue light and they have the scientific results to back it up.

Let's dive into the installation below.

RetinaGuard iPhone X Blue Light Filter Overview

The iPhone X is Apple's first premium mobile product and it deserves a premium blue light filter. If you're not careful with your device the iPhone X/XR/XS also comes with premium repair costs - a cracked screen alone costs $279 to repair.

Protect both your phone and your eyes with a tempered glass blue light filter from RetinaGuard.

With all the blue light filter choices out there, how do you pick a brand that works? RetinaGuard is certified by both SGS & Intertek to block 90% of blue light in the 380nm to 420nm range.

Package Contents

The package itself is vibrant and almost silky to the touch. It proudly displays everything you need to know - 9H rated coating, 0.4mm thin, 90% blue light blockage.

Included in the package are:

  • Alcohol prep pad
  • Dust free sticker
  • Microfiber cleaning cloth
  • Tempered Glass Screen Protector


Installation

A blue light screen protector is easy to install but don't rush through it. Considering you'll be looking at your mobile phone frequently, take your time with the installation.

Before you get started find a flat surface and clear out some space. A dining room, desk, or coffee table will do just fine.

Installation Step #1 - Clean & Dry

First, before getting started, be sure to wash and dry your hands to remove excess oils.

Second, use the provided alcohol prep pad to clean any crud off the device and wipe it dry with the microfiber cloth.

Installation Step #2 - Remove Dust

Anything on the surface of your phone will get trapped under the screen protector, so it's important to remove any speck of dust you see on the screen's surface.

Between the microfiber cloth and the dust free sticker, you'll have a spotless surface before placing the filter on the device.

Installation Step #3 - Place Protector

Now for the most important part.

Peel the bottom layer of the screen protector, careful not to touch the sticky part. Then, slowly line up the filter on top of the phone and stick it onto the phone.

Personally, I like to peel back the protective plastic about half way, line up the filter at the top and press down, then remove the remainder of the plastic.

Try not to remove the filter once it's placed.

Installation Step #4 - Use Wiping Cloth

Sometimes little bubbles appear after installing the screen protector - that's normal.

Use the same wiping cloth to smooth out the top of the phone. It may take an additional 24-48 hours for the filter to fully settle onto the screen.

If preferred you can release the air bubbles by pushing them to the sides of the phone.

Finished Product

You're finished! Your phone, eyes, and future sleep all thank you for installing a blue light filter on your mobile device.

Your screen protector should last you the lifetime of your phone. If you happen to drop your phone, the screen protector is designed to absorb the impact first and will shatter, saving the screen underneath.

Overall the colors of the display aren't distorted and I can't actually tell I'm using a physical blue light filter.

One thing I noticed about the RetinaGuard blue light filters is they tend to "glow" a blue/purple hue when under natural sunlight. This wasn't noticed under artificial lighting. You'll often see blue light filters and lens give off the same hue when reflecting light and it's completely normal.

Hardness and Water Test

Now that the blue light screen protector is installed, how does it perform? It's rated for 9H on the Pencil Hardness Test (not the Mohs scale) meaning it'll protect your screen from any scratches.

Throw your phone in your pocket with some keys? No problem.

Additionally, it protects your device from water damage as water droplets just roll off the screen.
