We just had kiddo's 4 year old check-up, and her vision test came up as 20-40. The pediatrician encouraged us to have her checked by an optometrist, and we can't get in with anyone until September. From what little reading I did online, it seems like this is likely not a big deal at this age and she's definitely not showing any issues in daily function, but hubby and I both have crappy vision that started in childhood, so we're wondering if this is cause for concern. Any experiences folks have around this?
