Im not really sure what 32/20 vision is, but they probably said 20/30. Which is still really good vision, It is just one line away from 20/20 vision, which is prefect vision. And you should have a dilated eye exam at least once a year, some times every two years, just depends on what your doctor says.Because unfortunately lots of eye diseases go completly undetected until you start to loose vision, and you dont get your vision back!!! So i would totally recommend for you to get an eye exam!! And dont forget to bring your sunglasses!!!!
