This video was about how and why some people need glasses.
Nearly half of all Australians need glasses or contacts. It could be because of the shape of their eyes or how much light the see too little can course you to have to where glasses or I could just be genetics. 4 out of 5 kids leaving high school need glasses. I now understand how people can come to where glasses. I also understand why people need to where glasses. Which is more common long sighted or sort sighted?
