Nothing can be concluded from the anecdotal reports of individuals. If there’s a real effect here it can only be seen in a statistical study of many subjects (and it seems there’s some doubt about the study’s replicability). So I don’t think anyone could tell you definitively whether your eyes manifested this effect, and it would be a mistake to treat the hypothesis as confirmed or undermined by any one person’s report.
