I have the same with my iPhone. Perhaps it's the distance that bothers us.

Since I was diagnosed with MG in May 2012, I have had a couple of eye "refractions," getting glasses prescriptions for computer glasses, reading glasses, distance glasses and combination glasses.
Then I order very cheap glasses online (zennioptical) and change them as my eyes change. The refractions cost me about $40 each-- just have my doctor do the lens testing, not the rest of the eye exam (have that yearly). My insurance covered part of this cost.
For $10 or if I am fussy, $25 I get a new pair of glasses. I find that as my eyes deteriorate during the day, switching glasses is quite helpful. I work out some of the special glasses prescriptions with my eye doctor so we can try things--including a double vision lens correction early on (didn't really work as my eyes were to variable).
I also set my computer to have much larger text and fool around with the contrast/background etc. There are "accessibility' type settings to help make things more readable.
Now with prednisone putting most of my eye problems into remission, I am mostly OK again, but I do try to look up every 10 minutes and look out at a distance for a minute or so -- out the window. By the way, I have been very happy with the zennioptical route for cheap -- but decent eyeglasses--$6 and up and a few weeks ago two for the price of 1 deal. I adjust them myself for my nose and fit--something that having worn glasses for 55 years and bent the heck out of most of them many times, I have learned to be quite easy to do when you have cheap glasses you don't worry about breaking!

I had that problem too, But I found out its just one eye being the problem, then causing the other eye to get tired and fuzzy and doudle vision, so I bought some glasses then took the lenses out and put scotch tape down the center of effected eye and my eye thing is gone , i even drive at night with them, and no double vision.

Last year when I was diagnosis my right eye would close involuntarily. I was put on 30 mg Mestinon and it stopped closing within a week. A month later the left eye would close involuntarily and kept doing it with a 60 and then 90 of Mestinon.

I was started on prednisone and went up to 30 MG. As I tapered down the left eye open and both were good for a year.

I was down to 17 1/2 mg and had a major upset at work. Co worker called me a bad name and it really upset me. Currently I am at 25 mg and will go up to 30mg tomorrow with my Doctor's blessing.

Scared to say I don't have double vision for fear of getting it.

Rest helps.

Sami thank you for this posting. My eye issues have been similar lately. Last week I wore my contact lenses for the first time this year and spent the day changing out my readers as my focus changed!

Russ, Thank You for sharing your "buyers guide". I know I'm due for an eye exam but have been reluctant due to the cost.

Sami, I'm sorry you were subject to the ignorance of a co-worker. As I type, I have seen two of you and it's a lovely sight indeed!
Larissa ;)

Larissam, you are so kind. Hope your eyes get better real quick.

My eyes have recently started giving me problems again. That is sometimes my red flag that I may see exaccerbation with other symptoms.
Thanks to all for the post and information.

It does make me wonder how long MG has been in my life. For years I've had problems with focusing. I've spent plenty of money on glasses that didn't help because my ability to focus changed from day to day, hour to hour, eye to eye. Interesting stuff.
