The optometrists and optical stylists at Metro Eye employ the latest trends in optical technology and artistry to examine eye orbs and deck them out in spectacular specs. More than 1,000 designer frames ($250—$1,000) from brands including Lindberg and ic! Berlin are fitted with customized prescription lenses (starting at $79), as are sunglasses ($189–$499) from shady style icons such as Kaenon Polarized and Serengeti Eyeware. In-house optometrists Dr. Amy Jankowski and Dr. Kaelyn Zaporski tend to sight-sockets during comprehensive eye exams ($130) that begin with a discussion of the patient’s medical history and include tests for vision-threatening diseases such as glaucoma, cataracts, and disco fever. Wavefront technology replicates daytime, dusk, and evening light, allowing the doctor to study each client’s vision under different conditions and personalize a prescription. The friendly docs provide a detailed description of their findings to help to guide patients toward the best course of optic action and back to their cars.
