I recently purchased glasses online for the first time, from EyeBuyDirect. I got a pair specifically for computer use, with a weaker prescription, smaller pupil distance, and lower index of refraction to cut down on chromatic aberration. For $45 I'm fairly satisfied, even though I haven't quite got the frames adjusted for a perfect fit yet. The chromatic aberration is still noticeable when I look for it, but definite…
How did you adjust the correction to get focus at say 3 ft / 1 m for computer use? Why a smaller PD?? I thought it was fixed by your skull anatomy?
Almost ungooglable, but I get the concept
