For any prolonged activity:

1) Like others who have responded, I do the above and recommend the same: "single focus reading glasses made to suit the distance the screen is away". Maintaining that distance is important. I have a bad habit of rolling my office chair out of focal distance when just reading from the computer screen. It is important to maintain the correct focal distance the glasses are set to.
2) For close work like reading a book, solder circuit boards, or using a laptop on a desk (book reading distance), I use another pair of glasses set to the focal distance from me to where I hold a book.
3) To watch TV, I use a different pair of glasses set to the focal distance from me to the TV Screen. 

This means I now use three pair of single focus glasses, all set to a different magnification and most importantly a different focal distance.

I do not require glasses for any other activity, my distance vision remains quite good.  I can peel vegetables for dinner without the need for glasses as it is not a prolonged activity.

I did try multi focus glasses at one time, but it made walking difficult as glasses set to the focal distance for reading or for computer screens made the the path all blurred. 

If I required glasses for reading the car's speedometer, then I would definitely be using a bifocal pair of glasses. So far I can easily read the instrument panel, and since most of the time we spend focusing on the traffic about us, a quick glance now and then to confirm the car's speed is under or at the current speed limit, I am able to drive for many hours. 

While I expect this is far more information than the OP required, my hope it might help the OP or others. It took me too long to find a good optometrist who was able to explain and help me with appropriate glasses set to the required focal distance.
