A contact lens is a medical device; hence, only an optometrist can measure your need for vision correction as well as determining which size and type of contact lens is best for you. In addition, the changes in your vision and eye health can only be detected by specialized equipment used by, and procedures performed by, eye doctors. Therefore, a prescription is a prerequisite to finding the perfect lens for you.

It is worthy of note that when contact lenses are not properly prescribed, your vision won’t be accurately corrected.
