As a mere bifocal (well vari-focal) wearer can I suggest a different approach. Stop wearing tri-focals or any other variable focus specs for reading a computer screen. Tell them to get a [very cheap] pair of single focus reading glasses made to suit the distance their screen is away. I did this years ago and wouldn't try to do it any other way now. The bliss of being able to read the whole screen comfortably without moving if I want to.
