Using the search box for keywords isn't always the best way to find your perfect readers. We encourage you to browse the categories. The categories can be found on the top of the page on a desktop, or using the hamburger menu of a mobile device. The reason why is search engines (including internal search engines as the one on DebSpecs.com) aren't great with numbers which hinders a power search. Also, by default it will give too many results on generic terms. For example, "blue filter blocker lenses" may also bring up frames that are the color blue. We can hone customer search terms to get redirected the the proper page, but we may not have discovered YOUR search term to fix it yet. It's best to get an idea of the #1 most important physical property for you. Is it the lens type? For example, "sunglasses" that are bifocal? Or the shape? Like say, aviator? Try to choose that category. ONCE in the category, you can further hone it by power, and gender. The more specific the category, the easier your search will be. For example, starting with "women's glasses" category may not be the best idea, because you STILL have to sort through about 50% of over 600 styles. It may be easier to start with a smaller category, like "sunglasses", then filter out the "womens". This video to learn the best way to quickly find your pair.
