Are there eye exercises to cure nearsightedness?

I was diagnosed with nearsightedness which means I can barely see distant objects. But I have no money for glasses let alone surgery.and my job provides us no health insurance. I have been searchin for natural ways and saw about some eye exercises but it doesnt go into detail about how to perform them. Does anyone know about this. How are they done and how long does it take for myopia to dissapear. I would get me some glasses but I barely have money for rent and to eat. I am lookin for cheap options .
