Why does my vision get fuzzy when i stand up and start walking?
Thursday, January 18th, 2007How can I keep my vision from getting worse?
Wednesday, January 17th, 2007What’s the difference between measuring nearsighted vision using negative numbers and the ratio out of 20?
Saturday, January 13th, 2007cc asked:
Is there a certain proportion that say, 20/100 vision translates to in terms of the strength that’s used to order contacts? I always hear people complaining that they have “really bad vision,” which then usually follows with them saying some measurement out of 20, like 20/80. What would my vision translate into if I’m -7.50 and -6.50 with contacts? Thanks.
