I’m a relative newcomer, still trying to figure out my first set of steps. It’s tricky with such prescription complexity! (high astigmatism, medium myopia) So I’ve been trying stuff out … slowly.
Here’s my question for the day: How do I know if I’ve made too big a CYL correction for my normalized glasses? And what would indicate that I might need CYL correction in my diffs?
Here are some things I’m noticing:
I can see very clearly out of the sides of my glasses (when I’m looking somewhat sideways there is no blur) but looking at something straight on creates a lot of blur.
The directional blur horizon for my normalized glasses starts pretty close, within ten feet.
Sometimes when I look at bright things at night (the moon, stoplights), I see very clear double vision! I haven’t been able to fully clear that yet.
The directional blur overall is slight but quite noticeable-- I can still see road signs pretty well and would feel quite comfortable driving, but things can feel a little distorted.
I’ve been measuring my astigmatism and haven’t noticed particular changes yet… but I’m not sure how long that might take to be measurable in that way.
I think I’ve been able to practice active focus with this – sometimes I blink and something gets clearer for a second – or gets clear double vision (if that makes sense). And sometimes I will stare at something for a while with no change.
For my diffs, I can see and clear blur… but it’s unclear to me at such close distances whether it is directional or just distance that is causing the blur.
So, again: How do I figure out if I’ve made too big a jump on my CYL correction?
Thanks so much.
