My father has been seeing floaters in his right eye for the past 5 days. It is like a thin hair he says that keeps moving and he sees it occasionally when he is walking during day time outside. He has no problems when watching TV. He is a bit disturbed about it although it does not disturb his vision. I have been giving him eye drops and his diet is healthy. He drinks tea and eats fruits. Gets good sleep as well. He is used to watching his phone in high brightness since past few weeks, but he has reduced this duration in the past few days. Kindly give us an opinion on whether this is a serious problem and what precautions we should take. Thanks.
