Though you should be careful about hygiene and put them out every night. A friend of mine fell asleep on the bus and didn't bother to put them out, she got an infection and was in the hospital for more then a month and later had to stay at home for quite some time too. I don't even remember exactly what they did, it's was some kind of operation where they had to cut some of the front eye off and then sew a transplant back. She got a few shots of medicine directly into her eye every day (with a needle). Half a year later the eee..

needed to be removed... arf my knowledge of English vocabulary is unsufficiant, how do you call the thread that holds a wound together? Checked in a dictionary and a thesaurus and I'm still not sure what word to use.
Lenses are great, luckily and a bit surprisingly I don't need them.

My mom needed glasses for reading early, my grandma has the sight on one eye inverted (what is on the right is seen on the left and vice versa - I can't really imagine how you see in her case because one eye is normal and the other inverted, but she says she never noticed until one or two years ago when she was at a doctor) and my father was more or less blind when he was born, had some operation after that but still has more than 7 dioptres.. with the good eye, that is. I'm so happy I can see well.
