Stronger prescriptions result in thicker lenses, especially in wrap motorcycle glasses. Thicker lenses are difficult to fit into wrap frames and also tend to cause the patient to experience the ‘fish bowl effect’ where images may look slightly bent towards the edges. Please read Motorcycle Glasses for Strong Prescriptions which covers the different frame options and lens technologies available for patients with prescriptions above +/- 3.00. We highly recommend patients with a SPH power above +/- 3.5 to give us a call at (877) BIKER-21 for recommendations.
