Apologies if this has been asked before, but are the upsells on prescription lenses worth it? There's just a plastic lens, then there's anti glare coatings and anti scratch coatings. My dad thinks that they just use one kind of plastic that already happens to be scratch and glare resistant, and get some people to drop an extra couple hundred bucks on it when they can. So is this true? Are some plastics better than others? Check my blog for more info but.... 1. All lenses are different materials. Most are variations of plastic, polycarbonate and mixtures of both. 2. Some materials are harder than others but they do not come with an anti-scratch material/coating. It is usually cured in different manners to make it more scratch resistant. 3. Anti reflection coating is DEFINITELY added onto it. It doesn't come with it all. Although there are lenses that come with the coating from the factory (which are the best because of the process they use) 4. Do places rip you off by making you pay more "options"? Of course!!! I have a post in my blog around large chains vs smaller shops. Check it out. The larger chains are all rip offs IMO. Go to the small guy, he will do so much more to keep you as a customer including using better quality frames and lenses. Larger chains are just trying to trick customers into promotions and stuff IMO. Im not going to tell you where and how to shop, but look around and do some research. Educated customers make sound decisions.
