Whether you’re trying contacts for the first time or need a new prescription, you must have a contact lens fitting. The Canadian Association of Optometrists advises that there are risks involved in buying your contacts online - -which is true when buying from a disreputable vendor and not doing your homework. However, with an eye exam, an in-person contact lens fitting and up-to-date prescription, you are fully ready to shop for the best deal from a reputable retailer online.
When scheduling your appointment, make it clear that you need a contact lens prescription. That way, your eye doctor can allocate enough time to perform all the necessary tests. Have your regular eye exam and your contact lens exam with the same doctor since it’ll save you trouble.
The first part of a contact lens exam is a standard eye exam. Your eye doctor will determine your prescription and refractive error using various lenses and letter boards. Next, he or she will perform cover tests. These tests analyze how well your eyes work together.
Now, your optometrist will move on to the contact lens fitting. These are the measurements that he or she will take.
