Hi, I'm hoping someone can point me in a direction for a product that I can use on my work-provided iMac. I have a sight problem and the reflective screen gives me awful headaches, currently I'm using an anti glare filter with a privacy feature built in but the screen is so big that the viewing angle through the filter means I can't see the whole screen without moving my head from one side of the desk to the other. Everything I've found so far has the privacy stuff built in. There's no upper limit on cost, my employer will be paying but they're unlikely to spring for a new computer with separate screens so please don't suggest a Mac Pro. Also, I'd rather avoid the thin adhesive film, I have enough difficulty applying those to a phone, let alone a 27 inch screen. Something that is removable would be better.
