Customer Reviews, including Product Star Ratings, help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.

Any peripatetic or domiciliary optical professional would find these useful in their bag of measuring and testing tools.
They're made from strong but flexible plastic and are very easy to use either singly or together.
At £4.99 for two (as at 6 July 2025) these are a cheap but effective and essential tool for any optical professional. Definitely worth considering.
