Oh trips! Do they know what is wrong with him (or might Dr Google actually be helpful here).
Ophthalmology didn't go as well as hoped. They'd not actually booked the twins in for an eye test, just a check. So we've still got to wait until the end of April to get new scripts/glasses 
Joshua's eyes are pretty good. They're happy with him as both his eyes are wonky, which means vision is equal and he wears his glasses happily.
Jennifer on the other hand, is much more of a worry. She only has one wandering eye, but they said her vision probably has got much worse since her first eye test - was noted she refused to cooperate for the second one. Her refusal to wear glasses obviously won't help, and she demonstrated it beautifully for me with a full on screaming, flailing tantrum when I tried to get her glasses on her. Have been told not to force it and maybe the prescription is too strong for her, as in she needs it but it's a big jump to get used to. So they've recommended she tries half the strength prescription when they test their eyes with a gradual increase to what it should be. So the sudden change isn't so upsetting.
They also had a student in with us and considering he was a final year student, I was slightly concerned. But mostly amused watching him follow Jen around to try and get her glasses on her. They are also going to try patching her to force her to use her bad eye. I'm guessing they'll be the sticky ones as there's no way she'll keep the soft one on over her glasses like Emily has.
On the plus side, they noted Jennifer's clumsiness and constant falling over. And it could well be down to her vision rather than anything else.
