Okay, that's a whole lot better than a tumor. Good luck.

Been to eye MD, they say there's no tumour in the eye, just keratoconus causing white reflex. Glasses for weakened vision and return appointment in 4 months.
Yes, that can be a serious symptom that can be due to a cataract or even a tumor within the eye. See an Eye MD as soon as possible.
