I've used honey in my eyes every single night when I was younger.
It improved my sight significantly at the time.
Difficult to do as it burns but helps.
Give it a try for two months and see if it helps you.
The eyes are the important part of our body and when it gets weak then there are two ways either you choose your natural treatment or you need medical treatment and if I suggest you that you should consult to any ophthalmologists to get proper eye treatment.
