I have an astigmatism in my left eye and was too lazy to wear glasses so I tried to improve my vision naturally, to my suprise it is possible. There are many excersices for improving your eyesight... one of those is actually practising with snellen eye charts (the standard ones used by most opticians). I am hosting one so anyone that wishes to practise using an interactive one. It also provides random characters, so no you cant cheat or memorise them http://scription.co.nr/test.html Stand 6 metres away from the screen and practise... The eye muscles will become stronger with practise, hence your focus will improve. good luck.
