Change in computer rx but not distance?

Hello, I am currently have 2 pairs of glasses one is for distance -4OD & -5 OS and a computer pair -2 OD & -2.5 OS.  I just went and saw my Opthalmologist because I felt my vision was a bit worse than before, he checked it and said there was no needed change in my distance Rx, but I explained that with my computer pair, I see more clearly out of the right eye if I tilt the glasses forward to an angle, so he said that means i need a weaker lens, so he bumped up my computer Rx to -2.5OD and -3OS, does this sound right, also how does it happen that my computer Rx would change, but my distance RX would be the same?  Thanks for your help!

The distance RX is the basic RX.  Computer/shopping/reading glasses are made by simpling "adding" magnifying or plus lens to them.

Eyes are not mirrow images of one another. One may see better than the other or hae more focusing power. (just like people often hear better out of one ear).

When you tilt glasses you change the power (like focusing binoculars).

If you can work in them I would not be concerned about minor differnce you only note with one eye covered.
