If you are a sunglasses retailer, you may already know that some of your customers have preferences for either plastic or metal frames, perhaps simply a choice of style and versatility – but some people actually have allergic reactions to glasses frames, more specifically, certain types of metal such as nickel. Some people are allergic to substances in plastic frames too, though. It would be good to have a wide stock of sunglasses of both plastic and metal frames so that a customer can choose either.
In addition to the actual composition of frames, additional substances in special lens coatings, or the silicone in the nose pads, or dyes and waxes applied to the frames may be an issue for allergen-sensitive persons. The most obvious way to tell an allergic reaction to sunglasses is when the reaction appears on the skin in the areas where the glasses typically rest on the face. The best way for these people to know what specifically triggers an allergic reaction on their skin, though, is to get some sort of allergy test. Then they can inquire about the contents used to manufacture their glasses and avoid those that have the substance they are allergic to.
