If you are approaching blindness, then you ought to see a specialist without delay. Islam teaches us to get treatments when we are sick. We know that the Prophet (peace be upon him) used to consult physicians and use medications and he told us in no uncertain terms: “Servants of Allah, seek treatments when you are sick, for Allah has appointed a cure for every illness except old age.”

 

If Zamzam water had been a cure for all conditions, he would have told us to use it instead of seeking treatments and consulting physicians.

 

Therefore, I would urge you to call your doctor and let him refer you to an eye-specialist immediately before you lose your vision. Otherwise, you will be guilty of a major sin: endangering your vision.

Almighty Allah knows best.
