Looking at the photo of the place, and reading that the glasses are paid for by Medicaid, this looks like a really bad choice as far as optical stores. It looks like a "welfare mill". "Transitions" is not a coating applied at a store, but a brand-name for a lens that changes colors. Other companies also make similar lenses, and like someone said, it is like "Kleenex" used generically and improperly. So I googled "eclipse" in the context of color-changing lenses, and there is no such company. Going by the column it is listed in on the receipt, and also going by the narrative that they went in the back of the store to make them darker, I believe this is simply the store's name for their coating - which does not adapt to light, but is a fixed color. That is a lot of money to be charged for a color coating, and the word "scam" is probably appropriate. Contacting Essilor would be a huge waste of time. A chargeback on the credit card would be one option. Complaining to Medicaid would be another option - probably the best choice.
the OP was. Medicare only is concerned when they are defrauded.
