Images being stuck on retina for longer than usual

Everyone has gotten that weird negative effect that you see when you close your eyes after having stared at or somewhere near a bright light. However as I understand, the after image should disappear quickly, what could cause an image to be stuck for what feels like longer than usual? Say a random house light for about 2 minutes or so. Is this normal?

Hi I have had 2 pvd in both eyes and I am diabetic..had a eye check apart from floaters all seemed ok…but just recently when I look through one closed eye I see a lilac little cloud but can’t see it through both eyes vision ok…I am short sighted as well… hate it and it worries me.:roll_eyes:

ive been experiencing this too, along with significantly increased floaters. i had a head injury about 8 months ago. been checked by 2 ophthalmologists recently and they both said i have no signs of PVD or retinitis. also having horrible anxiety about it. let me know if you find anything out. youre not alone
