The last time I got new glasses (from Costco), I specifically requested lenses that would minimise chromatic aberration. But they didn't have anything better than the high index lenses I already had. I have very bad eyes (rx of -8.25 and -8.00), which makes my lenses quite thick.
Are there other lens materials that do a better job of minimising chromatic aberration? I've tried researching this, but wasn't able to find anything.
