Hi Billy,
It is probably nothing to worry about but it is worth getting your eyes checked by a good optician if you have not had a check/retinal photography recently. Sometimes tightening up control suddenly can trigger changes but this is not that common. Another thought is that you may be experiencing “silent” migraines brought on by the hypo. These cause visual disturbances, sometimes with nausea, but no headache. If your BGs have run high for a while it is worth testing when you feel hypo to check that you really are as your body’s mechanisms can confuse themselves.
I hope to read that you have had your eyes checked within a day or two. If there is a sudden, severe and permanent change get to A&E as it could be a serious bleed or detached retina!
Regards,
Stephen
