Frankly, mine should too, but I took and pbutted my test at a time just before I had an eye test and got glbuttes; for the almost two decades since I've used glbuttes out of need.
The eyetest for drivers as it stands is grossly, criminally inadequate.
Merely being able to read a numberplate only demonstrates that vision in the centre of one eye is just about adequate to see a deliberately high-contrast target in full daylight; a driver is then permitted to drive in all weather conditions until they hit 70.
What needs to be done, ideally, is a quick machine-based eye exam (such as is common in hospital opthalmic centres) and a brief field of view test. Neither test takes all that long, and both, when combined with a quite eye examination combine to tell you a lot about the person.
Like, for instance, if they have a reasonable field of view, and if their sensitivity to differing light levels is good enough.
I am convinced that a fair number of road accidents are not caused by inattention but by defective eyesight, something which the extremely primitive testing of today will not pick up on.
