Drifting eye?

[Millificent]

I’m hoping the attached photo will show clearly enough. My DD had a very lazy eye as a youngster, years of patching seemed to do the job, plus corrective glasses. I was sitting with her earlier and I swear the same eye was wandering - approximately 15 years later! I managed to get a photo but of course it wasn’t showing as clearly as it was a few minutes earlier, but I think I can still see something.

Can anyone see what I mean?

I would have thought it was very common for someone with a lazy eye tendency to have it drift. All four of my relatives who've had a squint do have it return sometimes, usually when tired or when they take their glasses off. Three of them had surgical correction and one just had patching and glasses.

If this is new, I would guess your dd's glasses prescription may be wrong?
