How can improper lens fitting affect a customer?

Improper lens fitting can significantly impact a customer's experience by causing discomfort and visual issues. When lenses are not fitted correctly, they may lead to misalignments that strain the eyes, resulting in headaches, blurred vision, or difficulty focusing. Additionally, an incorrect fit may create pressure points on the face, leading to discomfort that discourages the customer from wearing their glasses regularly. Such issues can undermine the purpose of the lenses, which is to provide clear and comfortable vision. Therefore, ensuring that lenses are fitted properly is crucial in delivering a positive experience and effective vision correction for the customer.
