They come with a removable brow bar for a personalized look. The Fototec lens darkens as sunlight intensifies. Adjustable arm and nose pieces ensure a perfect fit for your face shape. Hydrophilic rubber pads stay in place when you sweat. The scratch - resistant, shatterproof polycarbonate lens provides 100% UVA/UVB protection and glare reduction. The optically decentered lens minimizes distortion. The frame is made of light and durable Grilamid TR - 90, with a vented shield frame. It includes fully adjustable hydrophilic nose and ear pads, suitable for medium - XL faces and weighing only 35G. A zippered hardshell case and microfiber cleaning bag are also included.

Using your Tifosi Aethon Cycling Glasses is easy. First, adjust the arm and nose pieces to fit your face shape for maximum comfort. Put them on just like regular glasses. When you're out cycling on a bright day, the Fototec lens will gradually darken to protect your eyes from glare. Remember, the hydrophilic rubber pads work best when they get wet, so they'll stay in place when you sweat. To take care of your glasses, use the microfiber cleaning bag to gently wipe the lens and frame. Avoid using rough materials that could scratch the lens. When not in use, store them in the zippered hardshell case to protect them from damage. If you want a different look, you can remove the brow bar. These glasses are designed for cycling, so don't use them in situations they're not meant for. Also, keep them away from extreme heat or cold to maintain their performance.
