QUESTION:
How come prescription glasses lenses become scratched after they have been used for only a few months?
This is one of the most common problems: why, although customers purchase lenses with anti-scratch coating, lenses become inevitably scratched?
ANSWER:
The answer to this question is really simple: the information the ophthalmologist gives to his patient is INCORRECT. This “misinformation” comes from the necessity of attributing a technical feature to an exclusively commercial need. When the optician proposes the “anti-scratch coating”, the patient thinks that those lenses WILL NOT GET SCRATCHED and that they do not need to be handle with care. This is false! It is true that a surface whit this kind of treatment is more resistant to scratches, but it is true as well that once it get scratched, the flaw is much more visible, so the product does not come up with the customer’s -wrong- expectations.
