My commentary on selected papers.
Commentary on Paper 2, Page 292 data, and calculated statistics for these four groups:
N = 48, Eyes = 96
Mean = + 2.21, Sigma = 1.31
N = 90, Eyes = 180
Mean = + 1.19, Sigma = 1.55
Older Children (Light School)
N = 97, Eyes = 194
Mean = – 0.93, Sigma = 1.97
Younger Children (Heavy School), 12 years.
N = 109, Eyes = 218
Mean = – 1.40, Sigma = 1.70
These values show that all normal eyes are dynamic. They control their refractive state, to the average value of accommodation of each eye.
(2) See Paper #5. I suggest you click on, “Graphics”, on this site. It shows how our normal eyes change their refractive state, from “positive” to “negative” as a natural process.
Adult Children, Age 21 – 25 (After 12 years of close work in school)
N = 41, Eyes 82
Mean: – 2.07, Sigma: 2.23
Parents, Age 46 – 50 (Minimum school, at that time.)
N = 20, Eyes 40
Mean: + 1.79, Sigma: 0.97
Commentary: Close work, created “negative state” in 85 % of these children.
Almost no close work, and virtually none of the parents had, “negative status”, i.e., no myopia.
This is the “deeper essential truth – for very clear distant vision, your refractive state must measure positive. The children, after doing the required close work for 12 years, had “negative state” that was very serious – problem. But this is still the normal eye controlling its refractive STATE to its average value of accommodation.
(3) This is the first truly accurate picture of the normal eye controlling its refractive STATE, to a clear cut “delta”, in its average value of accommodation. A similar experiment, with young monkeys – using contact lenses, proved that the normal eye would change its refractive STATE, in both direction. A -3.0 diopter caused a change of -2.3 diopters in about six months. A +3.0 diopter caused a change of +2.3 diopters in about six months. See, “Smith III” for details. This is a dynamic system – not a frozen box camera. (See “Smith III).

The Young Primate eye. Response of the normal eye to a confined environment. The accommodation system was changed, negative. The normal eye’s refractive STATE followed the accommodation system – as you would expect.
