There isn't a stereoscopics requirement for the JAA Class 1 at CAA HQ Gatwick as sterescopics is only useful for up to 20 metres or so. Past that it has been said that even those people with perfect stereoscopics vision use past experience to judge stopping distance. This is why peoiple with non-perfect stereoscopics vision can drive quite normally.
Straight from the CAA website:

Under the heading "Eye Function" on the last page:
You must have normal fields of vision.
You must not suffer from double vision.
Any degree of heterophoria (eye muscle imbalance) in excess of:
8 exo, 10 eso or 2 hyperphoria - measured at 6m
and
12 exo, 6 eso, 1 hyperphoria - measured at 33cm
will require further evaluation by an eye specialist at Gatwick.
There must be no acute of chronic disease in either eye or surrounding structures.
I couldn't type the prism symbol after each of the figures.
So it seems Tom had an evaluation done by the specialist as he was out of the initial limits and he was passed fit to fly...
