- 09:3709:37, 21 June 2020 diff hist −498 Bates Method I think it's sufficient to just say that we believe a stimulus is necessary. No need for quite so much detail. (I promise it wasn't just a knee-jerk desire to remove mention of hyperopic defocus !)
- 09:2409:24, 21 June 2020 diff hist +7 m Optics related math →Visual acuity equation: need to multipy rather than divide by 60 to convert degrees to arcminutes. I think it was just misinterpreting the original on the blog page.
