What is the difference relating a seclusion filter and anti-glare screen filter for a laptop? I want to reduce gl?

Frame-less peak filter:
provide only anti-glare coating alone

Frame-less privacy filter:
only the person directly within facade of the monitor can see on- screen facts
This device protects from scratches , fingerprints, or more serious prejudice
Filters attach and detach easily, and can remain in place when the Notebook is closed
Anti-glare surface with increased contrast

So go for Frame-less privacy filter!
