Not all eyewear sold on Opticsale.com comes with the option for prescription lenses. The availability of prescription lenses typically depends on the specific brand and model of the eyewear. Many popular frames do offer the possibility of adding prescription lenses, but it is essential to check the product details on the specific eyewear page for this information. Generally, customers can find a distinct section indicating whether prescription options are available. Additionally, some eyewear may be sold as non-prescription or as prescribed solely for sunglasses. For those interested in prescription lenses, the user should ensure they have their current prescription ready to select the correct options. For accurate information regarding a specific frame or model, customers are encouraged to look through the individual product pages on the website for the most reliable and up-to-date information.
