As per Nick. You do sometimes have to tilt your head a bit, but not a lot, when working on a screen but good positioning offsets that. I have shallow lenses, something like 22mm, so not much tilt required to change zones, which helps a lot. Cost varies a lot of course, but I think my last two pairs - one spare, one on - were £500 in total from Specsavers. That’s for short sight, slight astigmatism, medium quality plastic lenses, no tint or filter other than anti-glare. I’ve worn them for 10+ years, ever since I found multifocal contacts were no good for me. I work 60-70% of my time on screens what with email, pdf docs etc. etc.
