Oh sure, I don’t think I would have gotten surgery without multiple opinions!
But while there are no guarantees it sounded plausible and a few Google searches found other people saying it had helped, the downside is a quite high but not utterly ruinous expense on the thing I look at more than anything else, and even a pretty expensive retail computer monitor would only have to extend my useful eyesight by a comparatively modest period of time to pay for itself.
And while it very well may be placebo, it certainly feels less physically stressful on my eyes and facial muscles, so I don’t regret it even though I’ll have to cut the budget somewhere else.
