Late developing astigmatism
Anyone like to comment as to why after years of 6/6 0r 6/5 in both eyes no previously commented on astigmatism and still no requirement for near vision correction at 50, one eye should wander off over a year or so to +0.5 Sphere -2.25 Cyl Axis 170 (Near) ? Giving between 6/9 and 6/12 in that eye.
