Can I use EyeQue Refractive Measurements to order contacts?

EyeQue Refractive Measurements (ERM) is our trademark for the calculated measurements to correct your vision with eyeglasses based on the refraction error measurements and tests taken with the device. You cannot use the ERM for ordering contacts because an unexpired, signed prescription by a licensed optometrist or ophthalmologist is required, which we do not provide. Furthermore, contact lens prescriptions are more complicated to derive because they’re calculated differently from glasses due to the fact that they are in contact with your eyes, whereas the lenses for glasses are typically about 12 mm away from your eyes. While some people may have the same powers for their glasses and contacts, most people do not. In addition, contact lenses need to be properly fitted to the curvature of your eyes, so prescriptions contain additional parameters such as Base Curve and Diameter. Therefore, a professional evaluation is needed to determine the best contact lens prescription for your eyes, based on many factors, and to ensure proper fit and physical interaction with your eyes. Improperly fitted contact lenses may cause permanent damage and scarring to the surface of the eye, which could lead to vision impairment. The EyeQue Personal Vision Tracker and VisionCheck are only calibrated for eyeglasses.
