I have to laugh at my hubby. His arms are simply not long enough... however I'm the one with multi focal lenses... he's too stubborn.
I find it difficult to focus in dull lighting. And also have an issue where I can't switch between close up and distance. Close up is fine, but when I look up at the TV to read that or at a signpost, I can't actually focus on it initially. It takes a few moments to minutes for my eyes to actually adjust. The cause is strain on the ligaments controlling focusing. The solution is to make it easier to focus on close up objects (so less strain), so I have to use reading glasses despite not actually needing them for close up work... I'm certain the logic is backwards but it does help. However until I can actually press the character I'm after and not the one to it's side, my 'spelling' and the guesswork of the keyboard swiping and predictive text isn't going to get any better.... once I have my new glasses (hopefully by the weekend), I'll have to reset the dictionary and predictive text features on my phone (yeah, small keyboard doesn't help either) and tablet and teach it all over again! Curiously, I've just tested this by the way, I can focus without my glasses no further away than 12-15cm from my nose. (With my glasses I need a minimum distance of 20-25cm.) Hardly evidence of me needing reading glasses, lol.
I currently reset my dictionary about once a week. That and finding myself holding my head at an angle yet again was how I knew something was amiss again.
At least at present I have an excuse for my word blindness! Dyslexia and tiredness will be the problem next!
