bit of a long shot, but are there any opticians or ophthalmologists on here who would be willing to help me figure something out? i'm not after medical advice, just someone who knows about prescriptions who can maybe tell me why what's happening with my glasses/vision is happening from a description of a visual field issue.

(we've spent all day trying to work it out and we now know definitively (?) what it is, but we don't know why, and i'm not sure the optician will either, especially given that i'm having to explain in a language that's not my own. meanwhile though, i can't much see to work.)

thank you so much.

(please boost, if you don't mind)
