It has come to our attention that we need to make our customers aware of the "Types of Lenses" that are available in the Optical Industry! People (Including some Professionals) like to use different names and sometimes incorrect names for lenses, whether this is to confuse you or is a misunderstanding we are not sure? For either reason, we want to give you a lesson on the correct terminology and purpose behind each "Type of Lenses!" So you can make a confident decision about what you are doing when placing an order with us! Please Stay tuned as we will be doing the same again next week! - If you have any questions, please feel free to contact us either via phone or email! Thank you!
