Why are Fresnel prisms almost impossible to buy online?
Oh, this looks great, thank you! Hopefully the secretary can ask the ophthalmologist and he made a note of it - he said they were super expensive, but that’s really reasonable...

Haag-Streit are a optical equipment company, so would expect their fresnel prisms to do the job properly and hopefully without damaging coating. You’ll need to know strength of prism and base direction, and which eye. Until then keep patching. However eye dept should help out.

Thanks - St Thomas’s seem to be very good for eyes, with an eye casualty as well as a normal dept. First doctor couldn’t check properly because I’m too short sighted, so the most senior consultant saw me straight away rather than sending me home w/ an appointment.
