I have myopia - in fact it's turned into presbyopia the past couple of years.
Last December I had my eyes fitted for "gentle molding" contact lenses that I wear at night as I sleep and take them out in the morning. Now I can see 20/20 without any corrective lenses all day.
My eye sight was a -4.25 and a -3.75 and they were corrected to 20/20 within one week!
I've been wearing contacts/glasses since I was 9 - and I'm 43. I'm pretty excited about this, because my eyes were just getting worse and I'm amazed at the clarity I now see with.
