There are five seven handwritten zeros on that script. 4 of them have horizontal strokes to the left of the zero, with that stroke connected to the zero. Two of those are minus signs, two are the crossbars from the tops of a “5”.

The fifth zero is in the left axis field, which does not have a horizontal stroke connected to the zero. If the doctor wrote all their zeros with that weird tail to the top left, why does that one zero lack that tail?

Edit: There are also two zeros in the dates, neither of which have that weird line.

The answer is that they wrote all five seven zeros the same way, and four of them have deliberate horizontal strokes before them. Where those strokes aren’t from the fives, they can only be from minus signs.

I have never seen a cylinder correction of the opposite sign of the spherical correction: if one is negative, they are both negative.

Furthermore, I have never seen a positive spherical or cylindrical correction lacking a plus sign. If they intended a positive correction, they would have included an explicit “+” instead of nothing.

The axis Cylinder numbers are -0.25, and -0.50.

When you can’t see out of the glasses you ordered from Zenni, this is why.
