It doesn't fit Dell Latitude 14 7420 or 7430.I measured the screen protector. It is 10.25" x 7.1"Also the camera hole is on the right side - might be, it is for Galaxy Tab 11" screen - it fits well on my 10"

I have macular degeneration and spend a lot of time on my computer. this cover was very easy to install and I can not even tell it is there. My eyes do not hurt as they did quite often. Wish I had bought this sooner!

I suffer from dry eyes and this screen helps a lot. My eyes don't get as tired or light sensitive anymore.

Thank you, I have much less eye strain now and I love the little sticker slide to cover up the computer camera when it is not in use. It was about a 1/4 inch smaller than my screen, but it still works. I used it for a Dell Lattitude 3450.
