<p class="MsoNormal" style="margin: 0cm;"><span lang="EN-US"><span style="font-weight: bold;">Check PD - H Parameters.</span><o:p></o:p></span></p><p class="MsoNormal" style="margin: 0cm;"><span lang="EN-US">Before installing the lenses, ensure the optical insert is correctly shaped for the specific Scicon Sports Sunglasses model. The Nylor technology allows for customized shaping of the lens for both single-vision and progressive prescriptions. After installation, check the fitting parameters: pupillary distance (PD), optical center height of the lens (H), and make the necessary adjustments, particularly for progressive lenses.<o:p></o:p></span></p><p class="MsoNormal" style="margin: 0cm;"><span style="font-weight: bold;">Choose Spherical Geometry Lenses.</span></p><p class="MsoNormal" style="margin: 0cm;"><span lang="EN-US">For optimal performance, use prescriptions lenses with spherical geometry. Consider optical designs specifically suited to the frame type for best compatibility and vision quality.<o:p></o:p></span></p><p class="MsoNormal" style="margin: 0cm;"><span style="font-weight: bold;">Check Horizontal Alignment of Optical Center.</span></p><p class="MsoNormal" style="margin: 0cm;"><span lang="EN-US">Before removing the optical insert from the eyewear and mounting the prescription lenses, check the correct horizontal position of the insert demo lenses so that the optical center aligns perfectly with the pupil of the eye.<o:p></o:p></span></p><p class="MsoNormal" style="margin: 0cm;"><span style="font-weight: bold;">Refer to User Existing Prescription.</span></p><p class="MsoNormal" style="margin: 0cm;"><span lang="EN-US">For easier adaptation, base the prescription on the user’s everyday eyewear when installing lenses in the optical insert.<o:p></o:p></span></p><p class="MsoNormal" style="margin: 0cm;"><span style="font-weight: bold;">Consider Vertex Distance.</span></p><p class="MsoNormal" style="margin: 0cm;"><span lang="EN-US">Remember that using an optical insert reduces the vertex distance, which should be taken into consideration when fitting the ophthalmic lenses.</span></p><p class="MsoNormal" style="margin: 0cm;"><span style="font-weight: bold;">Compensate for High Spherical Powers.</span></p><p class="MsoNormal" style="margin: 0cm;"><span lang="EN-US">If the spherical power of the lenses exceeds +/- 3.00 diopters, make adjustments for horizontal prismatic compensation and factor in the reduced vertex distance due to the frame’s high frontal wrap.<o:p></o:p></span></p><p class="MsoNormal" style="margin: 0cm;"><span lang="EN-US">&nbsp;</span><span style="font-weight: bold;">Adjust for Prismatic Deviation.</span></p><p class="MsoNormal" style="margin: 0cm;"><span lang="EN-US">The Optical Insert has a frontal wrap angle that varies by model of Scicon Sports Eyewear and is typically greater than that of standard frames. This can cause horizontal prismatic deviation, which increases with higher lens powers. To correct for this, apply a horizontal decentration of +1.00 mm per eye for negative lenses and -1.00 mm per eye for positive lenses.<o:p></o:p></span></p><p class="MsoNormal" style="margin: 0cm;"><span style="font-weight: bold;">Verify Lens Centering.</span></p><p class="MsoNormal" style="margin: 0cm;"><span lang="EN-US">Before finalizing, check that the lenses are properly centered on the Optical Insert once mounted in the frame.<o:p></o:p></span></p><p class="MsoNormal" style="margin: 0cm;"><span style="font-weight: bold;">Apply Anti-Reflection (AR) Coating.</span></p><p class="MsoNormal" style="margin: 0cm;"><span lang="EN-US">Applying an anti-reflection (AR) coating to prescription lenses significantly improves visual comfort by minimizing glare and reflections. This enhancement leads to improved clarity, allowing for a more comfortable viewing experience. Additionally, AR coatings contribute to the durability of the lenses, making them more resistant to scratches and wear.<o:p></o:p></span></p><p class="MsoNormal" style="margin: 0cm;"><span style="font-weight: bold;">Warnings and Disclaimer.</span></p><p class="MsoNormal" style="margin: 0cm;"><span lang="EN-US">These guidelines are provided for informational purposes only for qualified opticians, aimed at facilitating the installation of prescription lenses into optical inserts for Scicon Sports eyewear. Scicon Sports assumes no responsibility for any adaptation issues faced by the customer due to centering errors, inadequate lens geometry, visual tolerance issues, lens selection, or technical decisions made by the optician during the fitting process.</span></p>

<p>Fitting prescription lenses into sports eyewear is possible, but it depends on the model and the available technology. The limitation is not objective, but rather technical or commercial, often due to a lack of experience in the field of sports optics. Not all opticians are specialized in this area, which is why it’s essential to consult someone with the right expertise to help you find the best visual solution for your sporting activities.<br></p>
