Contact lens selection and placement can be a very precise practice. Contact lenses are most often associated with a solution to provide glasses-free refractive correction but for many people, they can be medically necessary. With that in mind, there are many different types and powers of contact lenses designed to be specialty fit for each person’s unique eyes. It’s important that the doctor fitting you for contact lenses is an expert in the field. They must understand more than your refractive error; they need to understand the anatomy and condition of your unique eyes.
