High index lenses are used with particularly strong prescriptions, and are made of a material with a higher refractive index (pl 1.67) than standard index lenses - essentially, they can accommodate a stronger prescription in a lighter, thinner lens. If you suffer from the 'coke-bottle' effect from thicker lenses, you might want to give high index lenses a try. We recommend high index lenses for prescriptions stronger than +/-4.00 sphere, or for prescriptions that have both a significant sphere value and astigmatic correction (or cylinder value).
You will be able to select the package that best suits your needs in the checkout process after you enter your prescription.
The strongest prescription we can fill is -10.00 sphere, +6.00 sphere, or +/-4.00 cylinder. If you have a stronger prescription than these limits, you are welcome to purchase our frames without lenses and have your prescription filled locally by your optometrist. To do so, find your your favorite style and simply select "add to cart".
Our lenses are made from polycarbonate, one of the most shatter-resistant materials on earth. We also offer and high-index (thinner) for high prescription. You will be able to select the lens package that best suits your needs in the checkout process after you enter your prescription.
Classic Specs also offers Photochromic lenses that transition from clear to dark when exposed to UV light.
Every single pair of our eyeglass lenses are then finished with anti-reflective and scratch-resistant coatings, which are included in the purchase price of the glasses.
We offer free-form HD progressive lenses, which are made with the latest precision computerized surfacing equipment for the greatest clarity and most accurate prescription. We use an algorithm to calculate the segment height, in order to ensure you have the perfect prescription at every point in your lenses.
We do not offer bi-focal lenses at this time. Please email service@classicspecs.com to join the contact list for this product.
Prism prescriptions are for sensitive eyes and help to reduce muscular strain. They're best filled in person. For prescriptions containing prisms, we recommend you purchase our frames without lenses (starting at just $80) and then bring them to your optometrist to have your prescription filled locally.
