How much blue light does your anti blue light screen protector block?

Created by a professional and qualified Optical Medical Device R&D team, our medical-grade screen protectors can effectively filter at least 90% UV radiation in the spectral range of 200nm-380nm and at least 55% of harmful blue light in the spectral range of 380-480nm.


What's the difference between medical-grade blue light screen protector and the normal one?

Medical-grade blue light screen protectors are specifically designed to meet higher standards of durability, clarity, and eye protection compared to the normal one, blocking up to 55% of harmful blue light, while the normal one can only block around 30%.


How does your screen protector filter harmful blue light?

PerfectSight applies rare earth elements on the screen protector with 16 new upgraded processes and 8 professional-level protection to form a rare earth eye protection coating, which can effectively absorb the blue light and radiation emitted by the screen, creating a medical-grade protection layer.


Do privacy screen protectors work?

Yes, privacy screen protectors can effectively prevent others from viewing the content on your screen. If privacy is a concern for you, a privacy screen protector can be a useful accessory to consider.


What is the difference between high-definition phone screen protector and anti-glare phone screen protector?

The main difference is the display characteristics. High-definition (HD) screen protectors focus on clarity and maintain pristine screen quality, while anti-glare protectors reduce reflections and minimize glare, making the screen more readable in bright light conditions.


How to put on a screen protector?

Use alcohol wipes and a microfiber or lint-free cloth to clean the device screen thoroughly, align the screen protector with the device, and then slowly apply it from one end to the other, smoothing out any bubbles or imperfections as you go. Press down on the edges to ensure a secure fit. Please check our installation guide videos here.


How to get air bubbles out of a screen protector?

Gently lift the edge of the screen protector with a flat edge and use a credit card or your fingers to smooth out any air bubbles towards the edge. Push the air bubbles towards the nearest edge of the screen.
