Working on a laptop actually helps as it makes me look down while maintaining proper posture which is where the up close magnification lives. The big desktop monitor finds me learning my head back at times or working at the top. And I need the room brighter for the added depth of field from a constricted pupil.
The real problem you are going to bump into is when you have to read something off your phone or paper while doing something on screen. You need bifocals that are half mid/laptop- or further/monitor-reading and half close-reading. Try to find them! Anyone?
Turns out in the UK, they are illegal to buy without a specific prescription. Reading glasses + reading glasses = illegal! Because you might not go to an optometrist as often and might have glaucoma. Couldn't find them in the US but couldn't find whether that's because they are also illegal. Couldn't find any on Ali Express.
They're not super expensive, or super-cheap, but seem to work well enough. And I haven't had any issues with breaking them or anything.
EDIT: The brand is "Foster Grant".
-edit: I have a prescription, it makes the viewing better if you get exactly what you need, go back and get it redone if you are unhappy. The online retailers have generous exchange policies. (eg 39dollarglasses)
I'll ALWAYS have my dedicated computer glasses, the difference is incredible.
