Is there a big difference between negative 2.50 and negative 3.0 in eyesight prescription?

My contact lenses are presribed -2.5 for both eyes.
But my optomitrist said my right eye is a little bit worse than my left eye, so at one point, he gave me a stronger lens for just my right eye (I didn't check whether it was -3.0 or something else).
But now he prescribed my right eye back to -2.5, saying I should be fine in -2.5

going from -2.5 to -3.0, I couldn't tell much whether there was a change or not.
but is there supposed to be a significant difference between -2.50 and -3.0?
