Help my vision

Hi! I am Timeeca October. I am currently in my final year of my undergraduate degree. I have been struggling to improve my vision since I was in primary school. I have made appointments to numerous public hospitals applying for glasses. In my attempt I was unsuccessful. They are always fully booked or not taking appointments. This has made it difficult for me to study as my eyes hurt and cause headaches. I am a full time student on a bursary which makes it difficult for me to work at the same time. I come from a household in which nobody works and try to send my family money from my living allowance. This makes it difficult for me to pay for my glasses. I am therefore in need of your help to improve my situation. Any little bit would help.
