Posting my eyeglasses prescription here has got me out of a jam more than once since I started doing it, so I’ll continue the tradition: here’s the updated prescription for progressive bifocals I received this morning from Charlottetown Vision Care:

Moving back in time, here’s the 2016 prescription:

And the prescription from 2014, one I never had filled:

I’ve now enough data points that making a table is useful to see the evolution of my prescription:
Right Eye (OD)
My right eye, at least from the inside looking out, is the most challenged one: if I toggle back and forth between my eyes, whether wearing my existing prescription or without eyeglasses, the right eye is demonstrably weaker than the left.
The only change this time from the last prescription is in the “Add” column. This is described here as:
The Add, short for Reading Addition, is the additional correction required for reading, this can be used to make either reading glasses, bifocal glasses or Varifocal glasses. This figure is an indication of how much extra power is required ‘on top’ of the distance prescription for near or intermediate glasses.
On this prescription the “Add” went from +1.50 to +2.00:
| Year | Sphere | Cyl | Axis | Add | Prism |
|---|---|---|---|---|---|
| 2018 | +4.50 | -1.75 | 092 | +2.00 | 1.00 D |
| 2016 | +4.50 | -1.75 | 092 | +1.50 | 1.00 D |
| 2014 | +4.50 | -1.75 | 093 | +1.50 | |
| 2012 | +4.25 | -1.50 | 090 | +1.00 | 1.00 D |
| 2008 | +4.00 | -1.00 | 090 |
Left Eye (OS)
The stronger eye, which presumably why its “Sphere” measure (“the strength of lens required to correct your focus “) is less than the right. Again, the only change here is the “Add” from +1.50 to +2.00:
| Year | Sphere | Cyl | Axis | Add | Prism |
|---|---|---|---|---|---|
| 2018 | +3.25 | -1.00 | 062 | +2.00 | 1.00 U |
| 2016 | +3.25 | -1.00 | 062 | +1.50 | 1.00U |
| 2014 | +3.00 | -1.00 | 063 | +1.50 | |
| 2012 | +3.00 | -1.00 | 070 | +1.00 | 1.00 U |
| 2008 | +3.00 | -0.75 | 065 |
My optometrist assures me that there’s lots of room in the corrective spectrum to continue correcting my vision for years to come.
