Abstract
MacInnis is to be commended for bringing this new technology to the attention of the ophthalmic community.1MacInnis B. Metalens ophthalmic devices: the new world of optics is flat.Canadian Journal of Ophthalmology. 2018; 53: 91-93Abstract Full Text Full Text PDF PubMed Scopus (2) Google Scholar As with the laser, this engineering development began in the microwave domain and has evolved to include the visible spectrum. I have found 2 public domain sites that can help one understand the principles involved. Both are from the leading lab of Federico Capasso at Harvard. The first is a video clip showing a multicoloured plane wavefront passing through the meta layer and coalescing into a concentrated focus.2Pease R. Flat lens promises possible revolution in optics. Available at: www.bbc.com/news/science-environment-36438686. Accessed April 18, 2018.Google Scholar The second is a well-illustrated scholarly lecture by Capasso in which he delves into the phase manipulation of the wavefronts by the nanostructure of the metalens layer.3Capasso lab advance suggests industry role for flat photonics. Available at: http://optics.org/news/6/2/27. Accessed April 18, 2018Google Scholar Capasso makes the point that refractive index is not relevant to this discussion, but rather the Huygens-Fresnel principle. This new lens design could well rival refractive surgery and ocular coherence tomography in its impact on ophthalmology. The author has no proprietary or commercial interest in any materials discussed in this article.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
