Our FitOn® Sleek takes everything you love about our best-selling fit over polarized sunglasses and smooths them down into a sleeker, ultra-low-profile fit.

In the past, those who wore prescription glasses had to choose to go without sunglasses, pay a small fortune to have their prescription put into a pair of sunglass lenses or deal with cheaply made clunky coverup-style fit overs. Now, FitOn® Sleek polarized sunglasses from Eagle Eyes give you a much better choice.

FitOns® Sleek are high-performance, ultra-low-profile premium polarized sunglasses designed to fit comfortably and closely over your prescription eyewear. With FitOn® Sleek, you don't have to choose between style, clarity and performance. You can have it all.

Every pair of FitOn® Sleek sunglasses comes with Eagle Eyes' exclusive clarity-enhancing polarized lens technology: TriLenium®. Developed from original NASA optic technology, TriLenium® blocks out scattered blue light and 99.9% of harmful UV light rays, while enhancing colors and helping you see more clearly.

Take comfort, clarity and style to the next level with FitOn® Sleek.
