Approaches to Reduce or Eliminate the Risks of Sight Tests in Alberta
Bibliographic record
Abstract
This research report is motivated by two independent case reports featuring individuals living in Alberta, Canada who experienced permanent vision loss as a result of inadequate standards of practice surrounding sight tests. Sight tests are usually performed by opticians and are conducted independently of a comprehensive eye exam. A description of the two case reports in addition to a discussion of the potential dangers of sight tests provide evidence of the public health risks associated with sight tests. To investigate potential approaches to reduce or eliminate the risks of sight tests in Alberta, we conducted a jurisdictional review examining the laws and standards of practice governing sight tests in Canada, the United States, New Zealand, and the United Kingdom. Based on the jurisdictional review, the outright prohibition of sight tests in Alberta may be the best approach to protect the public interest and reduce cases of avoidable vision loss. As seen in other Canadian provinces, alternative approaches to reduce the risk of sight tests may involve 1) developing and enforcing restrictions around the performance of sight tests or 2) developing clearly defined scenarios in which opticians can collaborate with authorized prescribers to deliver safe sight tests.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
