Sources use different levels of certainty
The older Cats Protection staring article uses broad language about bonds and slow blinking. International Cat Care's handling guide says slow blinking may have more than one function, including communication when vulnerable. This site does not turn the stronger general wording into an individual love claim.
An observed blink is still a useful description
You can say that you saw the eyes close and open without deciding why. This page supplies no timing threshold and no requirement to count returns. It is not a reproduction of a study and it does not measure trust from a home exchange.
A blink is not touch permission
International Cat Care explicitly notes that slow blinking is not necessarily an invitation to stroke. The animal still needs choice about contact. A friendly interpretation does not override movement away, tension or other signs that interaction should stop.
Do not wait for the preferred response
A lack of a returned blink is not evidence of rejection or a weak bond. Do not stare harder, move nearer or repeat until the cat responds. This is a guide to the limits of an interpretation, not a task the cat has to complete.
