We all can just have our eyes once only, so we all should protect them well. When we have eye problems, we need to buy prescription eyeglasses to correct our vision. Then where to buy our prescription eyeglasses? My suggestion is that go to an eye care center with good reputation, for you can get a good eye examination there. With the correct prescription, then you can get yourself a pair of suitable prescription eyeglasses.

A dangerous prescription eyeglasses might be to just turn inward and become so involved with your internal processes that you forget to ask the customer.
The only thing you can do is to improve your value proposition is to move in a direction that takes value away. Instead of adding value of eyeglasses, you end up adding something that isn't perceived as such by the customer.
