But interesting info, CAA can deliver a Class 1 ( with a little trick on the regulation) for people over -5.00 with a deviation with restriction to airplanes registered in UK only, at your first renewal the limit becomes - 8.00 and then your deviation is removed and with no restriction enabling you flying all european airplanes.
Pity they can't do that for astigmatism: 2.0 diopter limit initial, 5.0 diopters for renewal.
