Why is blue light harmful?

The blue light we are filtering out is visible light that comes from the screen of your smartphone. It reaches directly into your eye and can damage your retina over the long term. Similarly, it can interfere with the production of the sleep hormone, Melatonin, which means if you use your screen during the evening, you might find it harder to get to sleep, or to sleep well.  

Will this work?

Yes, it will. We’ve designed, developed and tested this product rigorously and we are confident that it will filter harmful blue light without affecting your display at all. The fully tempered glass screen protector is one that we’ve been selling for a while, so we know it offers great protection too. 

Why are you adding the filter?

We believe in developing ways to help people enjoy technology and keep an eye on their health at the same time. Part of our commitment to originality is to do things differently. Research shows that prolonged screen use has the potential to cause damage if the blue light is not filtered. Like wearing your seatbelt, we think it’s better to be safe than take the risk. 

Frequently Asked Questions

How many times can I apply the OptiGuard Glass to my smartphone?

Only once, unfortunately. Re-applying the glass screen protector could attract dust under the surface, resulting in bubbles forming. To make sure you apply it correctly, check out our installation video and follow the instructions inside the box.

What happens if I crack my OptiGuard Glass?

Don’t worry about this. QDOS will replace your OptiGuard Glass screen protector under the lifetime warranty we offer when you purchase this product. Visit our Lifetime Warranty page and follow the instructions to get your replacement!

Why do I have to clean my device screen before I apply the OptiGuard Glass?

This is to make sure that there is no dirt, dust or grime on the screen. If there is, it will cause air bubbles to form underneath the protector, which will affect visibility.

I cleaned my screen before application and there’s still a bubble. What do I do?

If you’ve cleaned your screen before application and a small bubble still appears, don’t worry. You can remove these by applying gentle pressure from the bubble to the edge of the screen. If the bubble is still there, it should disappear after 24-48 hours. If you have any problems, don’t hesitate to contact our customer services at

How long will my OptiGuard Glass last?

The OptiGuard™ Glass Curve has been tempered for 4+ hours, giving it a top of the scales hardness rating of 9H! This being said, if it suffers a really nasty fall, it may break. However, we’ve given it a Lifetime Warranty, so should it break, visit our Lifetime Warranty page and follow the instructions to receive your free replacement! (See our terms and conditions)
