Choose your frame and click Select Lenses. Follow the guided steps to choose your prescription type, enter or upload your prescription, select the lens category, index, tint when available, and coating. Review all details carefully before adding the glasses to your cart.

Please use a current eyeglass prescription. For Single Vision lenses, enter SPH and, when listed, CYL and AXIS for both OD (right eye) and OS (left eye), along with your PD. You can enter the values manually or upload a JPG, PNG, GIF, or TIFF image up to 2 MB. Contact us if your prescription includes values not available in the selector.

No. Contact lens and eyeglass prescriptions are measured differently and are not interchangeable. Please use a valid eyeglass prescription from your optometrist.

PD, or pupillary distance, is the distance between the centers of your pupils, measured in millimeters. Choose Single PD if your prescription shows one total number. Choose Dual PD if it lists separate right and left values. If your PD is missing, ask your optometrist rather than guessing.

JamJam Lens currently offers Single Vision, Reading, and Non Prescription lenses. Compatible options may include Clear, Blue Light Blocking, Photochromic, Sunglass, and Gradient Sunglass lenses. The selector automatically displays the options available for your chosen prescription type.

Available lens indices may include 1.61, 1.67, 1.74, and 1.74 Plus. A higher index can generally produce a thinner and lighter lens for stronger prescriptions, but the highest index is not always necessary. Coating choices may include Standard, Blue Light Blocking, and Super Hydrophobic Coating, depending on the selected lens.

Yes. Select Non Prescription during lens selection. You can still choose from compatible clear, blue light blocking, photochromic, or sunglass options without entering prescription or PD values.

Compare the product measurements with a pair of glasses that already fits you comfortably. Pay attention to frame width, lens width, lens height, bridge width, and temple length. The three numbers printed inside many frames usually represent lens width, bridge width, and temple length in millimeters.
