Then she is old enough for an eye exam from an optician. They generally use drops which dilate the pupils and watch for response at this age. I started taking my kids to the optician at around 3 years as both my hubby and I are very short sighted. I wouldn't necessarily take her whilst she is still bruised, but once she is healed up then it won't hurt to take her and medicare will cover the cost if you go somewhere like Specsavers.
