Let me start by saying this: the Ocushield Anti Blue Light Screen Protector DOES deliver on its promises. After weeks of squinting at my MacBook Pro, I noticed an immediate difference in eye strain. The blue light reduction is legit—no more midnight Netflix sessions leaving me wired.

BUT (and it's a big but)... installation is a nightmare. The 'edge-only' adhesive design creates permanent bubble cities. I followed the tutorial, used the included microfiber cloth, and still ended up with what looks like a screen full of jellyfish. For £40+, I expected seamless application.

The privacy filter works surprisingly well—my nosy coworker can no longer 'accidentally' read my Slack messages from across the desk. Colors remain vibrant without that awful orange tint cheaper filters have.

Pro tip: If you have a completely flat-screen laptop (looking at you, Surface Pro users), skip this. The thickness of the adhesive strips creates unavoidable glare and bubbles that'll make you want to rip it off.

Final verdict? Great concept with flawed execution. Works miracles for eye fatigue if you can tolerate the bubbles, but there are better adhesive solutions out there for glass-screened devices.
