1. Use an Anti-Glare Screen Protector Mid-range and high-end smartphones already come equipped with anti-glare screen stickers. If your phone does not have this feature, you should stick it there. Screen defenders minimize glare and reduce the amount of blue light transmitted by the screen, reducing eye strain.

Otherwise, whenever you use your new phone, you should use the Bluelight Filter framework that came with it. Bluelight Filter for Eye Care is a third-party application that you can download and use from the App Store if your phone does not have such a framework.
