I used to suffer a lot when working on laptops/tablets. After having installed the Ocushield screen protector on my MacBook and iPad, those problems almost disappeared. Earlier, I couldn't even sit for an hour in front of my laptop/tablet, and now I can work continuously for hours without any problems. I will always be grateful to Ocushield for this. I have one request: I use Samsung phones, but there are no good anti-blue light screen protectors for Samsung phones, not even for the most expensive ones. Will it be possible for Ocushield to manufacture anti-blue light screen protectors for the Samsung Galaxy S21 Ultra 5G which was recently launched and is one of the most expensive phones in the Samsung line-up? I would really really appreciate that. Thank you.
