Aloevera and weak sightedness:

I read this article in a magazine. A girl has written her biography that she had severe pain in stomach and has very weak eye sightedness. 

When she got a severe pain she was told by someone to use aloevera. She started to use it nothing happened to her stomachache but when the doctors tested her eyes they surprise to see that she has normal eyesight now. Doctor asked her what you were using. She said i used aloevera for my stomachache. This was a story of adovacate girl. I read it few years back so i remember it. Once i felt sparkling around my eyes i wrote a letter to an old pious man he replied me to consult a good eye specialist. I also had headache so i used the same prescription that i ate 2inch piece of alovera in the morning and evening with empty stomach for few days and i get cured from my eye problems and headache.

Recite surah Kahf on Surma: put the surma in your eyes before going to bed with in few days your weak eyesight will be cured. Now a day due to too much TV, mobile, glasses, lenses, reading on bed, reading with improper pstures, sleeplessness, useless thoughts and tension make your eyesight weak and these are the reasons for sleeplessness too. Therefore, try to avoid all these.
