Science notes
The technical layer underneath the articles: structural computation and literature surveys on retinal bioenergetics and visual aging. Dry by design, and they assert no human outcome.

Named evidence
Claims that carry weight are tied to a specific trial, review, or professional body, listed at the end of every article. No “studies show” without saying which.
Education, not advice
Nothing here diagnoses, treats, or replaces an eye-care professional. Where the right answer is “book an exam”, we say so plainly.
Willing to say no
When the evidence does not support a popular product or habit, we write that, including when it would be easier not to.
