And yes, using one eye muscle can lead to fatigue of other muscles. That is why straining your eyes can lead to ptosis.
I was fortunate to reach a brilliant ophthalmologist who realized that I need three sets of eye-glasses so that I will need to do as little accommodation as possible.
I have one mutlifocal which is good for most distances, as long as I don't have to focus for long. I have one for reading, which is adjusted to the distance I use when I read and I have one for long distance (such as when seeing a movie).
This trick led to significant improvement in my visual abilities.

I have a similar setup with my glasses. My prescription is being changed at the moment so I can't see well in general, but two are ready to be picked up now. I have a multifocal with a small prism which helps for watching movies, and a little computer or reading work; a computer lens, which helps at about 30 inches; and a reading lens, which helps at about 16 inches. It gets pretty expensive, as insurance will only cover one pair, but I've found it works pretty well.
My optometrist won't make the reading lenses until he gets the computer ones right, so for the next couple months I'll probably be scanning anything I need to read and doing it off the screen. He gave me the option of doing the reading lenses first, but I figured this made the most sense.
